Re: [Drjava-users] Dr Java on OS X file IO questions

[Mathias R. <mgr...@ri...>]

Hi Joseph,

Thank you for using DrJava. Several of us are developing DrJava on
Macs. Mac OS is a bit different, but DrJava works just as well.

1. When you insert a flash drive, it gets mounted in the /Volumes
directory. For example, my MacBook's name is "manifold". When I go to
the File -> Open dialog and click on the drop-down menu at the top
that lets me select from a stack of directories, "manifold" is
displayed at the very bottom (above that, is often "Users", the user
name, and then perhaps "Documents").

When I select "manifold", I get to the root directory of my computer.
There, I select Volumes, and that's where my flash drive shows up.

2. Yes, you can put data files for file I/O anywhere you have read
and/or write access. My desktop, for example, is at
/Users/mgricken/Desktop. You can use absolute paths like that,
starting with a forward slash, or use paths relative to the working
directory.

3. You can create packages. Java specifies that the directory
structure must mirror the package structure. If you put a package
statement like

package foo.bar;

at the top of a file, then that file should be saved in a foo/bar
directory inside the directory that corresponds to the default
package. DrJava will try to work even with files that do not do this
correctly, but the results may not be perfect. It is best to follow
the Java specification.

By the way, this behavior is no different than it was on Windows.

4. The "Project Root" of a project should be the directory that
corresponds to the default package. For example, if I have the files
for the package com.domain.xx.yy.zz in the
/Users/mgricken/Desktop/myProject/src/com/domain/xx/yy/zz directory,
then the project root should be /Users/mgricken/Desktop/myProject/ .

5. There really aren't that many differences between Java or DrJava on
the Mac and Java or DrJava elsewhere. The user interface is a bit
different, paths to files are different, but largely, DrJava and Java
in general are cross-platform. Any DrJava or Java text should do.

I hope this helps. If you have further questions, please let us know.
I have created a support request on SourceForge to help us keep track
of the issue:

[Drjava-users] Dr Java on OS X file IO questions

[Joseph A. <drt...@gm...>]

I've recently switched from Windows to Mac.  I'm using Dr. Java  20100816 on a Mac OSX 10.6 Snow Leopard.

 I'm encountering some problems relating to the file structure on the Mac, which doesn't seem to have drive letters.
(the texts and examples I have are for windows systems).

1. I can't seem to use my flash drive, either for source or for data files, from inside Dr. Java;  
the only disk I can see in the selector box on the open window is the "Macintosh HD"

2. Can I put data files for File IO in a directory other than the "Working" directory? How?

3. Can I create packages in Dr. Java?
When I include a package statement, I keep getting errors saying the package name does not match the directory name.

4. What is the relationship between the Dr.Java Project and the Java Package?
Specifically, how do I set the project properties to fit in with my com.domain.xx.yy.zz   package directory?

5. Are there any books or documentation specifically addressing Dr Java (or just Java in general) on the Mac?

Thanks for your help,

Joseph Austin

[Drjava-users] DrJava Stable Release 20100816-r5366

[Mathias R. <mgr...@ri...>]

Dear DrJava Users:

We have made a new stable version available: drjava-stable-20100816-r5366

You can download it from the DrJava website at http://drjava.org/
or from SourceForge.net by following this link:

http://sourceforge.net/projects/drjava/files/1.%20DrJava%20Stable%20Releases/drjava-stable-20100816-r5366/


You receive this email because you have subscribed to a DrJava mailing list.

Available for download at http://drjava.org  .

DrJava is a lightweight programming environment for Java designed to
foster test-driven software development. It includes an intelligent
program editor, an interactions pane for evaluating program text, a
source level debugger, and a unit testing tool.

In addition to bug fixes, this stable release includes a number of new
features introduced after the last beta release:

These features include improved keyboard shortcuts, improved undo/redo
functionality outside the Definitions Pane, as well as better menus
for detached windows on the Mac.

Note: Java 1.4 compatibility has been dropped. To use DrJava, you will
need Java 5 or newer.


New features since the last beta release:

 - Keyboard shortcuts for Project menu items.

 - Menus for detached windows on Mac OS.

 - Undo/Redo for Input Box and detached Interactions Pane.

 - Keyboard shortcuts available in detached windows.

 - Displaying compiz warning only for Java older than 1.6.0_20.

 - Changing the default look-and-feel for non-Windows, non-Mac
   machines (=Linux) to the system default. This will probably
   be GTK instead of Metal, which is much prettier.



Bug fixes since last beta release:

 - Properly disabled 'Run Project's Main Class' if main class not set.

 - Bugfix for a problem relating to menu item availability, which
   caused the project menu to be disabled when it should be enabled.

 - IllegalAccessException with Smart Run on non-Public class.

 - Fixed NullPointerException when removing Find All matches

 - Fixed a bug that caused a NullPointerException when a Find All
   encountered a missing file

 - Fixed bug StringIndexOutOfBoundsException on non-Western systems
   that use characters longer than a byte.

 - Fixed bug that caused Undo/Redo menu items to not be enabled
   properly

 - Fixed bug that caused pressing Ctrl-Z (Undo) to make the System.in
   box disappear

 - Fixed bug that caused { or } to be inserted on Linux when using
   "Go to Opening/Closing Brace" shortcuts.

 - Fixed a bug that enabled Undo for the Interactions Pane on Macs
   even when there was nothing to undo.

 - Fixed problem that prevented configuration of key bindings for
   actions with the same names, e.g. "New" (File) and "New" (Project).

 - Fixed bug that caused changes to Key Bindings to not be canceled
   properly


New features since the last stable release:

 - The Eclipse Java Compiler is now integrated into DrJava. DrJava
   therefore does not require the JDK anymore to compile
   programs. Note that the JDK is still required to use the debugger
   or to create Javadoc.

 - DrJava supports the OpenJDK and JavaMint (multi-stage programming
   in Java; see http://www.javamint.org/ ) compilers.

 - JUnit 4.7 support.

 - ConcJUnit support (for concurrent unit tests; see
   http://www.concutest.org/ ).

 - Access control for private and package private members now enabled
   by default.

 - DynamicJava (Interpreter) error messages are much better,
   especially those involving method and constructor invocation.

 - Added support in DynamicJava for explicit type arguments in local
   function invocations (x = foo(23)).

 - The Breakpoint, Bookmarks, and Find Results tabbed panes now have
   Previous/Next buttons and associated keyboard shortcuts for simpler
   browsing.

 - The Interactions Pane working directory can now be specified even
   when not using projects.

 - If DrJava cannot start, for example because of bad memory settings
   in the Preferences, DrJava will suggest that you let it reset the
   Preferences.

 - The preferred compiler can now be set, and this setting will be
   restored when DrJava starts the next time.

 - Zoom for Print Preview.

 - New Class wizard.

 - Save Copy ability for Definitions documents, Interactions Pane and
   Console Pane contents.

 - The Java Language Level facility has been simplified. There now is
   only one language level called "Functional Java", using the file
   extension .dj. It is comparable to the Intermediate level and
   can still compile .dj0 and .dj1 files. .dj2 files are compiled
   using the Full Java compiler. DrJava will suggest that you rename
   .dj0 and .dj1 files to .dj files, and .dj2 files to .java files.

 - DrJava can generate a custom .jar file of itself that includes
   additional files. There is a Tools/Advanced/Generate Custom
   drjava.jar menu item that takes the current DrJava executable file
   and a number of user-specified files to generate a new jar file.

    * The libraries included in the new jar file will then
      automatically be included in the classpath and be usable without
      adding them to a classpath somewhere.

    * There is no functionality to remove the libraries again from the
      modified jar file.

    * Generating a custom DrJava jar file disables the check for
      updated versions. Otherwise a user may download an updated
      version that doesnt have required libraries anymore.

 - When DrJava encounters missing files during a "Find All" search,
   it will ask the user whether to continue or abort the search.

 - Improved "New Java Class" dialog with some auto-completion.

 - Better feedback when Java API data is loaded, which may involve
   some delay if it is retrieved from the internet.

 - There is a new option in Preferences/Interactions Pane
   called "Smart Run ('java') Command". If enabled (default),
   the "Run" button and the "java" command in the Interactions
   Pane detects if the class (a) is an ACM Java Task Force
   program (subclass of acm.program.Program) or (b) an applet.
   If (a), then it runs the program's main method, but inserts
   "code=MyClass" as argument 0. If (b), it starts the
   applet viewer. Otherwise, the "java" command behaves just
   as before.

 - Right margin line.

 - Improved Save As file naming.

 - Tools->Advanced->New DrJava Instance feature.

 - Appending .jar to file name when generating custom DrJava.


Bug fixes since the last stable release:

 - Fixed some indentation bugs.

 - Fixed some GUI initialization problems that prevented DrJava from
   starting on some systems.

 - Fixed a bug that prevented DrJava from opening on MacOS 10.5 or
   10.6.

 - Fixed compiler error when closing curly brace missing.

 - Fixed NullPointerException in Jar Project dialog.

 - Fixed a bug that prevented users from editing External Processes.

 - Fixed a bug in un-commenting source code.

 - Fixed a bug in displaying the Auto-Import dialog in the
   Interactions Pane.

 - Improved suggestion to increase interactions JVM heap.

 - Improved responsiveness when selecting a compiler.

 - Fixed a bug that prevented users from generating Javadoc of
   Language Level files.

 - DynamicJava (Interpreter) bug fix allows the declaration of
   interfaces.

 - Miscellaneous small DynamicJava bug fixes make it much more robust
   and correct, including better handling of member lookup, inner
   classes, enums, interfaces, raw types, static imports, switch
   statements, casts, and final variables.

 - Bugfix for comparing 0.0 == -0.0 and NaNs.

 - Bugfix in DynamicJava: Supports annotation declarations

 - Bugfix in DynamicJava: Fixes parser bug for enums

 - Bugfix in DynamicJava: Fixes implicit accessibility of interface
   members

 - Bugfix in DynamicJava: Fixes checking of assignments from character
   literals

 - Bugfix in DynamicJava: Improves checking of casts

 - Bugfix in DynamicJava: getClass() is a special method with type
   Class for all classes

 - Bugfix in DynamicJava: Improves error messages for inner class
   references

 - Bugfix in DynamicJava: Preserves location in wildcards

 - Bugfix in DynamicJava: Catches errors that occur during static
   initialization of a class

 - Bugfix in DynamicJava: Short-circuiting during type checking

 - Bugfix in DynamicJava: += for strings

 - Bugfix in DynamicJava: Array initializer is assigned to a non-array
   type

 - Misc improvements to DynamicJava SoureChecker

 - Bugfix that prevented users from watching local variables in the
   Debugger.

 - Smaller Java Language Level fixes.

 - StringIndexOutOfBoundsException During Next Word

 - Exception when double click on External process tab

 - This commit fixes some glitches in the new functional
   LL, effectively subsuming both the Elementary (.dj0)
   and Intermediate (.dj1) language levels.

 - Bugfix for throw null

 - Fixing a memory leak in DefinitionsPane.

ability to use the built-in Eclipse compiler, the OpenJDK and JavaMint
compilers.

Note: Java 1.4 compatibility has been dropped. To use DrJava, you will
need Java 5 or newer.

New features since the last stable release:

 - The Eclipse Java Compiler is now integrated into DrJava. DrJava
   therefore does not require the JDK anymore to compile
   programs. Note that the JDK is still required to use the debugger
   or to create Javadoc.

 - DrJava supports the OpenJDK and JavaMint (multi-stage programming
   in Java; see http://www.javamint.org/ ) compilers.

 - JUnit 4.7 support.

 - ConcJUnit support (for concurrent unit tests; see
   http://www.concutest.org/ ).

 - Access control for private and package private members now enabled
   by default.

 - DynamicJava (Interpreter) error messages are much better,
   especially those involving method and constructor invocation.

 - Added support in DynamicJava for explicit type arguments in local
   function invocations (x = foo(23)).

 - The Breakpoint, Bookmarks, and Find Results tabbed panes now have
   Previous/Next buttons and associated keyboard shortcuts for simpler
   browsing.

 - The Interactions Pane working directory can now be specified even
   when not using projects.

 - If DrJava cannot start, for example because of bad memory settings
   in the Preferences, DrJava will suggest that you let it reset the
   Preferences.

 - The preferred compiler can now be set, and this setting will be
   restored when DrJava starts the next time.

 - Zoom for Print Preview.

 - New Class wizard.

 - Save Copy ability for Definitions documents, Interactions Pane and
   Console Pane contents.


Bug fixes since the last stable release:

 - Fixed some indentation bugs.

 - Fixed some GUI initialization problems that prevented DrJava from
   starting on some systems.

 - Fixed a bug that prevented DrJava from opening on MacOS 10.5 or
   10.6.

 - Fixed compiler error when closing curly brace missing.

 - Fixed NullPointerException in Jar Project dialog.

 - Fixed a bug that prevented users from editing External Processes.

 - Fixed a bug in un-commenting source code.

 - Fixed a bug in displaying the Auto-Import dialog in the
   Interactions Pane.

 - Improved suggestion to increase interactions JVM heap.

 - Improved responsiveness when selecting a compiler.

 - Fixed a bug that prevented users from generating Javadoc of
   Language Level files.

 - DynamicJava (Interpreter) bug fix allows the declaration of
   interfaces.

 - Miscellaneous small DynamicJava bug fixes make it much more robust
   and correct, including better handling of member lookup, inner
   classes, enums, interfaces, raw types, static imports, switch
   statements, casts, and final variables.

 - Bugfix for comparing 0.0 == -0.0 and NaNs.

 - Bugfix in DynamicJava: Supports annotation declarations

 - Bugfix in DynamicJava: Fixes parser bug for enums

[Drjava-users] DrJava Stable Release 20090821

[Mathias R. <mgr...@ri...>]

Dear DrJava Users:

We have made a new stable version available: drjava-stable-20090821-r5004

You can download it from SourceForge.net by following this link:

https://sourceforge.net/projects/drjava/files/1.%20DrJava%20Stable%20Releases/drjava-stable-20090821-r5004/


You receive this email because you have subscribed to a DrJava mailing list.

Available for download at http://drjava.org .

DrJava is a lightweight programming environment
for Java designed to foster test-driven software
development. It includes an intelligent program editor,
an interactions pane for evaluating program text, a
source level debugger, and a unit testing tool.

In addition to bug fixes, this beta release includes
a number of new features introduced after the last
stable release:

These features include default imports for the
Interactions Pane, inner classes as main class for
projects, Javadocs and auto-completion
for JUnit, Javadocs and auto-completion for user-defined
libraries ("Additional Javadoc URLs").

An applet viewer is included, and classes that extend
Applet can be run using the "Run Document as Applet"
menu item (under "Tools") or using the "applet MyClass"
command in the Interactions Pane.

The debugger has been improved and now includes
an automatic trace feature to step through the code
at a user-determined interval, array element watches
in the debugger, and the ability to debug language level
files without seeing the Java code that they get
translated to. The debugger also retains the imports
that have been made before the last step was taken
or a breakpoint was hit.

DrJava can now also associate source, project and
add-on files with DrJava so that they can be opened
by double-clicking on them in the Windows Explorer
or MacOS Finder (.java, .drjava, and .djapp files).

The source browser was improved: Browse forward
and backward like in a web browser!

Since there still is an incompatibility between
Sun's Swing GUI library and the the Compiz window
manager on Linux, we now check for the presence
of Compiz and display a warning.

Notable is the ability to close the System.in stream in
the Interactions Pane and an automatic update feature
that downloads new versions of DrJava automatically.

The most important bug fixes include changes to the
language level converter, compatibility with network paths,
a debugger deadlock, and color preferences.

Note: The default project file extension now is
.drjava, not .xml anymore.

Note: Java 1.4 compatibility has been dropped with this
release. To use DrJava, you will need Java 5 or newer.


New features since the last stable release:
- Interactions pane options: Require variable types,
require semicolon, access control checks for private
and package private members.

- File associations in Windows and Mac OS.
- Improved source browser.
- Display and select from all installed JDKs.
- Reorganized Preferences dialog.
- Compiz warning.
- Interactions Pane parser allows annotations.
- Completed support for nested classes (static and
  non-static) in Interactions Pane.

- The System.in stream can be closed by pressing Ctrl-D
when in the input box.
- Imported classes and packages can persist over
breakpoints and debugger steps. To enable or disable this,
change the setting in the Debugger tab of the Preferences.
- Default imports for the Interactions Pane
- Inner classes as main class for projects
- Javadocs and auto-completion for JUnit (3.8.2).
- Javadocs and auto-completion for user-defined libraries
("Additional Javadoc URLs")
- Automatic tracing in the debugger.
- Array element watches in the debugger.
- Automatic update feature ("Help/Check for New Version")
- Applet viewer
- Multiple key bindings per action
- Improved Jar creation dialog
- Find All/Replace All can be limited to a selected
section of code

Bug fixes since the last stable release:
- Bug fixes for Language Level facility.
- Updated JGoodies Plastic look-and-feel.
- Bug fixes for Interactions Pane: arrays, break
statement, switch, non-void main methods.
- NullPointerException After Closing File with Error
- Mac OS X Java VM selection for 64-bit

- Bug fix for Icelandic keyboard to allow
  braces { } to be entered.
- Miscellaneous Interactions Pane parser bug fixes.
- Bug fixes in type checking in Interactions Pane.
- Implemented qualified super expressions in
  Interactions Pane.
- Fixed name resolution issues involving circular
  dependencies.

- When the "java MyClass" command is used to start a
program in the Interactions Pane, the command is not
translated to "new MyClass().main(...)" anymore, but
retained as "java MyClass".
- If DrJava is unable to restart itself, e.g. if the heap size
is too large for the machine, DrJava asks the user if it
should reset the configuration and try again.
- Javadoc 6 is now linked correctly in the "Open
Javadoc" feature.
- Several bug fixes related to unit testing and the debugger.
- "Open Java API Javadoc for Word Under Cursor..."
has been fixed.
- Better behavior for next/previous word and selection of
word by double-clicking in Definitions Pane.
- Fixed syntax highlighting and interpretation of long literals
and hexadecimal literals
- Fixed problems with modal dialog boxes when the user
switches to another application.
- Fixed a memory leak.
- Several language level fixes.
- Filtered ASCII text when pasting.
- Fixed network paths in projects.
- Colors can now be configured again.
- Documents that have been closed are not re-opened
again if they contained failing unit tests.
- Removed a deadlock when debugging unit tests.
- Debugging language level files does not open the
generated Java code anymore; line numbers in language
level files are correct.
- Closing a file does not remove all breakpoints and
bookmarks anymore.
- Fixed "No Test Cases" in Find/Replace panel
- Empty files are not considered "out of sync" anymore
during JUnit testing

[Drjava-users] DrJava Eclipse Plug-in 20090115

[Dan S. <dl...@ri...>]

An update to the DrJava Eclipse plug-in has been posted.

Release Notes:

This update to the DrJava Eclipse plug-in integrates bug fixes,  
performance improvements, and new features added to DrJava over the  
last two years. Significantly, the Interactions interpreter has been  
rewritten to fully support generics, type inference, and other Java 5  
features. The plug-in also improves compatibility with the latest  
versions of Eclipse.

CHANGED INSTALLATION INSTRUCTIONS:

Unzip drjava-eclipse-20090115-r4708.zip to access the plug-in jar  
file: edu.rice.cs.drjava_0.9.9.20090115-r4708.jar. Copy the plug-in  
jar to your Eclipse installation's plug-in directory. Additional  
packaging (README, etc.) may be discarded.

Re: [Drjava-users] DrJava Stable Release Update 20080904

[Dan S. <dl...@ri...>]

A DrJava stable release update has been posted.

Release Notes:

Available for download at http://drjava.org. This is a minor update to  
the recent stable release, fixing a bug in the execution of unit tests.

Notes from the original stable release (20080828):

Most prominently, a bug in JDK 1.6.0_04+ has rendered previous stable  
versions of "drjava.exe" unusable when compiling with affected JDKs (a  
"Cannot read zip file entry" error will occur). This release addresses  
the issue.

Major new features include i) an improved Interactions interpreter  
with full support for generics and ii) integrated support for external- 
process-based tools. Performance of "Find Next" and "Find All" has  
been dramatically improved, as well as the performance of auto- 
indenting.

The project file format has been changed (as of release  
drjava-20080415-1537-r4441). Previous DrJava version will not  
recognize the new project file format.

Users may also notice i) an optional platform-information survey at  
startup, and ii) automatic background checking for new DrJava  
versions. (Both of these can be turned off.)

[Drjava-users] DrJava won't compile. Using IcedTea 7

[Zambini <zam...@gm...>]

Greetings!
This is my first post so bear with me;

I'm using Dr.Java in one of my classes and I can't get it to compile. I've
reinstalled Ubuntu 7.10 numerous times thinking that I had a corrupted
install of JDK and/or Ubuntu. 

I'm using "drjava-stable-20080106-0744" and "icedtea-java7-jdk" on a freshly
installed Ubuntu 7.10 Gutsy Gibbon

I have done "locate tools.jar" as well as found it manually, and told
Dr.Java in the preferences window where it was, and it still says "Compiler:
None" and wont compile. I've used it successfully on a Windows laptop, and
its the same code that successfully ran on said laptop. 

Is there something I'm missing? I have all of the necessary software and I
have it set up correctly (so I think at least).



Here is some additional info about the software I have installed:

me@computer:~$ java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea Client VM (build 1.7.0-b21, mixed mode, sharing)


me@computer:~$ javac -version
javac 1.7.0-internal


me@computer:~$ sudo update-alternatives --config java
There are 2 alternatives which provide `java'.

  Selection    Alternative
-----------------------------------------------
          1    /usr/bin/gij-4.2
*+        2    /usr/lib/jvm/java-7-icedtea/jre/bin/java

me@computer:~$ sudo update-alternatives --config javac
There is only 1 program which provides javac
(/usr/lib/jvm/java-7-icedtea/bin/javac). Nothing to configure.



me@computer:~$ locate tools.jar
/usr/lib/jvm/java-7-icedtea/lib/tools.jar
^ is what I have located in Dr.Java preferences.

[Drjava-users] can't compile using fedora 8 and IcedTea

[Skunk W. <sku...@ve...>]

Hi,

I am using Fedora 8, X86_64, IcedTea (IcedTea is RedHat 
compiled/distributed OpenJDK).

I have used the 32 bit Sun JDK with DrJava on 32 bit Fedora 8 in the 
past without any problems.

However I can't compile on this new machine.

$ java -jar drjava-stable-20080106-0744.jar

...runs and navigates code, etc. but there is no compiler available.

I ran updatedb and locate to find the tools.jar file, which I added to 
the Edit-Preferences->Tools.jar Location :

/usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0.x86_64/lib/tools.jar

And when I unzip the tools.jar file it has classes below javac :

$ ls sun/tools/javac/
BatchEnvironment.class  CompilerMember.class  ErrorMessage.class 
resources          SourceMember.class
BatchParser.class       ErrorConsumer.class   Main.class 
SourceClass.class

Also command line "java" and "javac" work :

$ java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea 64-Bit Server VM (build 1.7.0-b21, mixed mode)

$ javac -version
javac 1.7.0-internal

And the "alternatives" system looks okay :

$ /usr/sbin/alternatives --config java

There are 2 programs which provide 'java'.

   Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.7.0-icedtea.x86_64/bin/java
    2           /usr/lib/jvm/jre-1.5.0-gcj/bin/java

$ /usr/sbin/alternatives --config javac

There is 1 program that provides 'javac'.

   Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/java-1.7.0-icedtea.x86_64/bin/javac

Any idea on what is missing? Or are there some more tests I can run to 
see how and where the javac resource is getting lost?

[Drjava-users] New Beta Release

[Mathias R. <mgr...@ri...>]

Hi everyone:

I just released a new beta version of DrJava. Please take a look at
the new version:

http://sourceforge.net/project/showfiles.php?group_id=44253&package_id=50477&release_id=563171

After the limited discussion we had yesterday, I decided to create a
branch based on revision 4268, the last version before Dan integrated
the new interpreter. Then I merged the last changes I made in revision
4286 into the branch, so the beta has all the bugfixes and features of
the latest version on http://www.cs.rice.edu/~javaplt/drjavarice , but
not the new interpreter.

Please try to stress this new beta version as well as the drjavarice
version with Dan's interpreter. If I don't hear of any major problems,
I will make a new stable release based on the same branch during the
first few days of the new year. In mid-January, we will then make a
new beta release that also includes the interpreter.

I hope you agree with this course of action. I wish you and your
families happy holidays.

--Mathias

Re: [Drjava-users] A begginer question

ok i downloaded the 1.6 (Kit 6 Update 3) and it seems to be fine.
Just one last question.
In school when I run the program, when the drjavav need to print to the use=
r
something (lets say: println("Enter a number") it's open a window (pop-up)
and in the 1.6 it just write it in the interactions (bottom screen), can i
change it to the pop-up thing?.. it's more comfortable..
thx,

The class java.util.Scanner was introduced with JDK 1.5.  If you can =20
install a newer JDK than 1.4.2 on your computer, you should be in =20
business.  You can get one from java.sun.com.

[GuyG <gu...@wa...>]

Hello, I'm really new in the DrJava thing, I'm learning it right now in

I downloaded the drjava from : http://drjava.org version:
drjava-stable-20070828-1759, I got the compiler (JDK 1.4.2_16)
Now, I've done this newbie program:
{code}import java.util.Scanner;
public class Boom7
{
  public static void main(String[] args)
  {
    Scanner in=3Dnew Scanner(System.in);
    int a;
    System.out.println("Enter A Number");
    a=3Din.nextInt();
    if (a%7=3D=3D0)
    {System.out.println("Boom");}
  }
}{code}

but when i try to compile it sais:

{code}3 errors found:
File: D:\=D7=AA=D7=95=D7=9B=D7=A0=D7=95=D7=AA\drjava\Boom7.java  [line: 1]

[Drjava-users] drjava.org domain lost, please use http://drjava.sourceforge.net/

[Mathias R. <mgr...@us...>]

Hi!

Unfortunately, we missed the renewal deadline for the drjava.org
domain, which has now been picked up by a domain squatter. We are
trying to reclaim the domain.

In the meantime, please use the following URL:

http://drjava.sourceforge.net/

We apologize for the inconvenience.
