Class Viewer 6.0.0

Class Viewer is a Java Swing application for viewing public information about Java classes, including methods, constructors, fields, interfaces, and inheritance.

This release preserves the existing application version reported by ClassViewer.java. It is a maintenance release package prepared from the source tree on 2026-08-26.

Requirements

• Java 8 or newer
• A graphical desktop environment

The release was compiled and smoke-tested with OpenJDK 21. The application uses the Java SE reflection, Swing, SAX, and AWT APIs only; no third-party libraries are required.

Run the application

From this directory:

java -jar ClassViewer-6.0.0.jar

To open an initial class, pass its fully qualified name:

java -jar ClassViewer-6.0.0.jar java.lang.String

Keep ClassViewerConfig.xml beside the JAR. It supplies the documentation locations, local browser/editor settings, and known packages. The defaults currently reference Firefox ESR and gedit; change those values for your system.

Contents

• ClassViewer-6.0.0.jar — compiled application
• ClassViewerConfig.xml — runtime configuration
• src/ — complete Java source and configuration source
• COPYING — GNU General Public License, version 2
• COPYING.LESSER — GNU Lesser General Public License, version 2.1, for the reusable utility classes
• SHA256SUMS — checksums for release files

Source build

The source package includes build.sh. From the source root, run:

./build.sh

That script compiles into a temporary build directory and creates the application JAR with com.jstevh.viewer.ClassViewer as its entry point.
