+= Compiling java code using gcj =
+
+Java source code (.java files) can be compiled using the command 'gcj'.
+
+For example:
+{{{
+#!sh
+gcj HelloWorld.java
+}}}
+
+This example will not work, however, as gcj must be told which main method to run when specifying source files, for example:
+
+{{{
+#!sh
+gcj --main=HelloWorld -o HelloWorld HelloWorld.java
+}}}
+
+The parameter "--main=<className>" tells the compiler that the executable should run the main within the !HelloWorld class and the "-o" parameter specifies the output file.
+
+If the code is successfully compiled, the executable will be a file named "!HelloWorld in the current working directory. If no output file is specified, the executable will be the file named "a.out" in the current working directory.
+
+Run the program from the current working directory with the following command:
+
+{{{
+#!sh
+./HelloWorld
+}}}
+
+To compile to java bytecode (.class file), use the -C option:
+
+{{{
+#!sh
+gcj -C HelloWorld.java
+}}}
+
+This command will produce "!HelloWorld.class" which can then be run in the java virtual machine:
+
+{{{
+#!sh
+java HelloWorld
+}}}
+
+Notice that you only specify the class name, not the bytecode file name.
