GCJ是一款用于Java编程语言的便携式、优化型、提前编译器，能够将Java源代码编译为Java字节码或直接编译为本地机器码。它还支持从Java字节码到本地机器码的转换。GCJ编译的应用程序会与运行时库libgcj链接，提供核心类库、垃圾回收机制及字节码解释器等功能。libgcj支持动态加载和解释类文件，从而实现混合编译/解释的应用程序。

The GNU Compiler for the Java^TM Programming Language

GCJ is a portable, optimizing, ahead-of-time compiler for the Java Programming Language. It can compile Java source code to Java bytecode (class files) or directly to native machine code, and Java bytecode to native machine code.

Compiled applications are linked with the GCJ runtime, libgcj, which provides the core class libraries, a garbage collector, and a bytecode interpreter. libgcj can dynamically load and interpret class files, resulting in mixed compiled/interpreted applications. It has been merged with GNU Classpath and supports most of the 1.4 libraries plus some 1.5 additions.

GCJ can also be configured as a cross-compiler, suitable for embedded systems programming. Recent versions of the GNU Debugger support GCJ (short tutorial).
