Jades
Java distributed executor service library
This Java library provides the class DistributedExecutorService which implements java.util.concurrent.ExecutorService. The goal is to distribute tasks across a network of machines (nodes) over SSH. The API is designed to be as user-friendly as possible : 1. Instantiate DistributedExecutorService 2. Add nodes 3. Submit tasks The only requirement is that all machines have SSH and a compatible JRE (>= 6). More precisely, when a node is added, the application's jar is automatically copied (scp) to the node and a new server started (ssh). Handling of access restrictions is left to the user (ie you can type your password every time or use authentication keys). Nodes can be added dynamically. When a node is added, workers are created according to the node's processor count. Eg, a cluster of 4 quadcores will give 16 workers. -

Jafaran
Fast and more random implementations of java.util.Random.
Jafaran (Java Fast Random) provides fast, and for some more random, implementations of java.util.Random, with additional nextXXX() methods, and methods to retrieve and restore state. The names of implementations contain "Conc" (for concurrent) if they are thread-safe and non-blocking, or "Seq" (for sequential) if they are not thread-safe. Also provides an implementation of Ziggurat algorithm (based on J. A. Doornik paper, 2005), used by nextGaussian() methods of the provided implementations. Requires Java 5 or later. Also available on github since 2015/12/13: https://github.com/jeffhain/jafaran Principal classes: - Implementations using Mersenne-Twister algorithm (good pseudo-randomness): MTSyncRNG MTSeqRNG - Implementations using Marsaglia Xor-Shift (fast): MXSIntSeqRNG (32 bits) MXSLongSeqRNG (64 bits) (nextLong() faster, larger period) - Ziggurat: Random-based implementation of Ziggurat algorithm. -

JarOMine
Quickly Search THOUSANDS of Archives!
If you have ever tried to locate files, classes, and resources buried amongst an ever shifting locus of ZIP and / or JAR files, we feel your pain! After spending far too much time searching hundreds of archives for moving targets, I decided to write JarOMine. Originally designed for locating Java classes, JarOMine works equally well with ZIP archives, too. -

Jasper2Docx
JasperReports exporter to Docx document
[EN] An implementation of a JasperReports exporter that produces Word 2007 document (docx format) from a report. The difference between this library and the JasperReports default exporter is the mission to produce the less number of tables in the Word document, that is to obtain a document based on text paragraphs instead of tables, easy to edit. [IT] Implementazione di un convertitore di un report prodotto con JasperReports in un documento in formato Word 2007 (docx). A differenza del convertitore di default di JasperReports, questa libreria cerca di ridurre al mimino la produzione di tabelle per ottenere un documento Word orientato al paragrafo, quindi più facilmente modificabile. -

Java Basics
Large educational repository for learning and reviewing modern Java
Java Basics is a large educational repository for learning and reviewing modern Java, currently presented around Java 25. It combines conceptual notes, code examples, programming exercises, interview questions, and multiple-choice material. Core topics include collections, strings, object-oriented programming, multithreading, and general Java programming. Separate resources cover JDBC, JSP, Servlets, Hibernate, and common design patterns. The repository also contains dedicated Java program collections for hands-on practice and problem solving. Its broad structure makes it useful for beginners, interview preparation, and developers refreshing specific Java concepts. Content is organized as a long-form reference rather than a single application or course project. -

Java Client for Google Maps Services
Java client library for Google Maps API Web Services
This library brings the Google Maps API Web Services to your server-side Java application. Each Google Maps Web Service request requires an API key. API keys are generated in the 'Credentials' page of the 'APIs & Services' tab of Google Cloud console. The Java Client for Google Maps Services is designed for use in both server and Android applications. In either case, it is important to add API key restrictions to improve the security of your API key. Additional security measures, such as hiding your key from version control, should also be put in place to further improve the security of your API key. -
