The Java Compiler Compiler (JavaCC) is a compiler toolkit that allows people to develop compiler front ends quickly. We can use JavaCC as the lexical analyzer (scanner) generator, parser generator, and semantic analyzer generator (generating the abstract syntex tree).

JavaCC is completely written in Java.
It generates recursive descent (top-down) parsers and allows you to specify both lexical and grammar specifications in your input grammar. In terms of syntactic and semantic lookahead, it generates an LL(1) parser with specific portions LL(k) to resolve things like shift-shift conflicts. The input grammar may be in extended BNF notation.
