Java programming resources

This is an overview of the various pages that I offer related to Java programming. The selection of topics (e.g. compilers, but not IDEs) is arbitrary and reflects just my personal interests. By no means is this site supposed to be complete.

Java development tools

• Compilers for the Java programming language
  • bytecode compilers — tools that translate Java source code (.java files) to bytecode (.class files)
  • native compilers — tools that translate either source code or bytecode to native executables (e.g. .exe files under Windows)
• Java virtual machines (JVM), development kits (JDK) and runtime environments (JRE)
  • JDKs and JREs - complete packages to either develop (JDK) or run (JRE) Java applications, applets etc.
  • standalone JVMs - mostly research projects that rely on an external class library implementations
  • embedded systems - environments that run on systems with limited memory and CPU resources, sometimes integrated into the operating system
  • just-in-time (JIT) compilers - mostly integrated in the JVM, they convert bytecode on demand to faster machine code
• Java class file optimization and compression - tools and techniques to reduce the size of Java class files

Java code examples

Small working programs to demonstrate how to do things with the standard runtime library. Each page has detailed explanations of what the program does, step by step, in a beginner-friendly way. Mostly image-related.

Java and images

• Java libraries to read and write image files
  • pixel image file formats - also called raster or bitmap file formats, e.g. JPEG, GIF, BMP, TIFF
  • vector image file formats - e.g. SVG, WMF, DXF
• Java image FAQ - frequently asked questions and answers around Java and images.
• Image code examples - part of the above mentioned code examples section.
• Creating thumbnails with Java—article describing problems and issues around thumbnail creation.

Other Java resources

• Introduction to Java — explains some basics, links to other resources, mentions tools.
• Java libraries to read and write document files:
  • PostScript (PS),
  • Portable Document Format (PDF),
  • DVI (device-independent, standard TeX output format),
  • Excel spreadsheets (XLS),
  • PowerPoint presentation documents (PPT).
  • Word documents (DOC).
• Software written in Java — a small list, by no means complete.

My own Java projects

Links to various software packages which I implemented in Java.

• JIU (Java Imaging Utilities)—library to load, edit, analyze and save pixel images [GPL]
• ImageInfo—Java class to extract width, height and color depth from image files [Public Domain]
• Lucene Wikipedia indexer—index Wikipedia article data with the Lucene text search library.
• ffident—Java file format identification—library to identify file formats, similar to file(1) [LGPL]
• Juta (Java Usenet Traffic Analyzer)—process Usenet postings stored as text files [GPL]
• jpegextractor—program to extract JPEG streams from arbitrary files [LGPL]
