Hi, I am looking for information about writting a Java Parser in C. All I want the parser to do is get keywords, operators, variables, etc and output this information to a file. It doesn't have to be fancy for anything. I have alot of psuedo code already done for this but it would be nice to have some more help to see how I can implement certain things and if I am doing some things right.
Also, white space and commits are ignored.

You can find just about everything you want to know about Java here, which provides grammars and lexical structure. You could probably just store the keywords, operators, etc. as constants and search/compare each token. Variables would be the tokens that do not match one of the constants. Anything beyond lexical analysis would require you to implement the grammar (which is not that difficult since it is found in Sun's documentation).
