Several people have worked on a parser for Java.  I have one based
on PCCTS (Purdue Compiler-Construction Tool Set) that recognizes most
of Java, builds a parse tree and walks the parse tree.  Terence Parr
and some people associated with him have also done work on a
Java parser (also based on PCCTS; they have more experience than
I and have most likely done a better job).  And a yacc grammar 
is available.  (PCCTS, BTW, is a yacc/lex replacement.)
