<p><b>JavaCC</b> (<b>Java Compiler Compiler</b>) is an <a href="Open-source_software" title="Open-source software">open-source</a> <a href="Parser_generator" class="mw-redirect" title="Parser generator">parser generator</a> and <a href="Lexical_analysis" title="Lexical analysis">lexical analyzer</a> generator written in the <a href="Java_(programming_language)" title="Java (programming language)">Java programming language</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
</p><p>JavaCC is similar to <a href="Yacc" title="Yacc">yacc</a> in that it generates a <a href="Parser" class="mw-redirect" title="Parser">parser</a> from a <a href="Formal_grammar" title="Formal grammar">formal grammar</a> written in <a href="Extended_Backus%E2%80%93Naur_form" title="Extended Backus–Naur form">EBNF</a> notation. Unlike yacc, however, JavaCC generates top-down parsers. JavaCC can resolve choices based on the next <i>k</i> input tokens, and so can handle <a href="LL_parser" title="LL parser">LL(<i>k</i>)</a> grammars automatically; by use of "lookahead specifications", it can also resolve choices requiring unbounded look ahead. JavaCC also generates lexical analyzers in a fashion similar to <a href="Lex_(software)" title="Lex (software)">lex</a>. The tree builder that accompanies it, JJTree, constructs its trees from the bottom up.

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