GCJ - Definition and Overview

The GNU Compiler for Java (GCJ) is a compiler for the Java programming language that comes as a part of the GNU Compiler Collection (GCC). It can compile Java source code to either Java Virtual Machine bytecodes, or directly to machine code for any of a number of CPU architectures. It can also compile class files containing bytecodes or entire Java archives (JARs) containing such class files into machine code. Almost all of the runtime library used by GCJ comes from the GNU Classpath project.
