Free java compilers software for linux

The Java Brainfuck Compiler is a compiler for the uniquely powerful Brainfuck language, which produces Java bytecode that will run on any Java Virtual Machine (with no intermediate steps such as going by way of Java code).

Java Games project is a collection of simple games that are compiled into Java applets and meant to be played online in a Web browser.

Currently the collection contains four games: XO World (similar to tic-tac-toe, but with lines of 5 on a 10x10 board); 100 Mack (guess the random combination of 4 images out of a set of six); Memory (flip 2 plates at a time to find matching pairs); and Tetris.

Java Tetris project is a simple Tetris game.
Java Tetris is a game written with Eclipse and the VE Plugin. It is a nice starting point if you want to learn Java and Eclipse.
The game can be started as Java applet or Java application.
Enhancements:
- The dependency on jdom was removed.
- The jar is now only 30kb.
- A bug was fixed in the score list.

State Machine Compiler takes a state machine stored in an .sm file and generates the state pattern classes in nine programming languages.
Its features include default transitions, transition arguments, transition guards, push/pop transitions, and Entry/Exit actions. State Machine Compiler requires Java SE 1.4.1 or better.
Enhancements:
- This release cleans up C# and VB.net debug output using System.Diagnostics.Trace.
- It fixes a number of minor bugs.

Java Bomberman project is a multiplayer game for Java.

Instructions

First of all start a bomberman server by typing...

# java BombermanServer [-port 1033 -speed 3 -timeout 300]

You can use the -port option to change the default port number.

You the -speed option to change the player speed at game start (default 3). The option -timeout changes the timeout (default 300).

After the server has started successfully you can start several clients by typing...

# java BombermanClient [-name nickname -port 1034
-host 127.0.0.1 -serverport 1033
-quiet
-music
-theme ice
-x 0 -y 0

Java-GNOME application is a set of Java bindings for the GNOME and GTK libraries that allow GNOME and GTK applications to be written in Java.

The Java-Gnome API has been carefully designed to be easy to use, maintaining a good OO paridigm, yet still wrapping the entire functionality of the underlying libraries.

Java-Gnome can be used with the Eclipse development environment and Glade user interface designer to create applications with ease.

Java-Gnome is part of the official Gnome Bindings Release, commiting us to high quality regular releases.

Java Network Stack provides a Java library for research oriented network programming.

Java Network Stack is a library used by the DIMES project to create new internet measurements. It provides a clean API for packet manipulation, send, receive, filter, and analysis. It is a unification of raw socket capabilities, MAC level networkingm, and IPv6 capabilities.

The Java Exorcist projects aim is to create a small and easy to use tool, that can be used to extend the Java language syntactically. Why would you do that? There are basically two reasons:
First, you just might want to fix your pet-peeve in the language itself. For example, create new keywords like unless, foreach, new operators, or generate setter getters automatically for a bean property.

Secondly, you might tune the language itself for a specific project, so the project code may look more clean and thought out. For example: specific logger keyword, which automatically checks (if statement) whether the logger should be invoked or not, or even ommits the whole logging compile-time, when its disabled! Or create a method modifier transaction to enclose the whole method in a project specific transaction.

How it works on the outside

Exorcist is a compiler of extended Java code. The compiler can be used in command-line mode, or through Ant. Basically, with no extensions configured, Exorcist only compiles the standard java code. To extend the language, you can plug in classes, which extend a single interface of the exorcist framework, and implement a single (and simple) method. Thats it.

How it works inside

Exorcist works like a pre-processor. It translates the extended language into plain Java code, and then compiles it using the standard Java compiler (javac).

To analyze a language, there are two steps involved. The first is a Lexical analysis, the second is the Parsing of the lexical tokens. Lexical tokens are strings, numbers, operators, dots, semicolons, etc. These are also called terminal symbols, because they can not be analyzed further. During parsing, lexical tokens are read, and non-terminal symbols may be produced.

These include things like: expression, method body, declaration, if-statement, etc. The Exorcists tranformation engine works basically with lexical token lists. Each extension first matches itself to the start of the received token list, using terminal and non-terminal symbols freely. If the match is detected, the extension is free to modify the input token list as it pleases, and with it modify the output clean Java source code.
