'''JavaCC''' (Java Compiler Compiler) is an [[open source]] [[parser generator]] and [[Lexical_analysis|lexical analyzer]] generator for the [[Java (programming language)|Java programming language]]. JavaCC is similar to [[yacc]] in that it generates a [[parser]] from a [[formal grammar]] written in [[Extended Backus-Naur form|EBNF]] notation, except the output is Java source code. Unlike yacc, however, JavaCC generates top-down parsers, which limits it to the [[LL parser|LL(k)]] class of grammars (in particular, [[left recursion]] cannot be used). JavaCC also generates lexical analyzers in a fashion similar to [[Lex_(software)|lex]]. The tree builder that accompanies it, JJTree, constructs its trees from the bottom up.
