JavaCC (Java Compiler Compiler) is an open source parser generator for the Java programming language. JavaCC is similar to Yacc in that it generates a parser for a formal grammar provided in EBNF notation, except the output is Java source code. Unlike Yacc, however, JavaCC generates top-down parsers, which limits it to the LL(k) class of grammars (in particular, left recursion cannot be used). The tree builder that accompanies it, JJTree, constructs its trees from the bottom up.

JavaCC is licensed under a BSD license.

History

In 1996, Sun Microsystems released a parser generator called "Jack". The developers responsible for "Jack" created their own company called Metamata and changed the "Jack" name to JavaCC. Metamata eventually became part of WebGain. After WebGain shut down its operations, JavaCC was moved to its current home.
