GCJ: An optimiser for Java. Unravelling the acronym takes a little doing. GCJ stands for GCC Java. In unix, the command line name for the C compiler is 'cc'. GCC is the GNU cc. GNU itself stands recursively for: GNU Not Unix. gcj is the Java front end to the GNU Compiler Collection (gcc). It can read .java and .class files. It can generate object code or .class code. gcj comes with its own runtime, which on some platforms includes a (slow) bytecode interpreter. The class libraries are still incomplete. gcj will appear in the upcoming gcc 3.0 release. Snapshots and the like are available for the curious.
