java parser

[mickey0]

Hello,
I have to write a descendant recursive parser in Java. what do you suggest? Any links with java code example, please?

instead of java , I suggest u to use Vb which would make it easier for u.

Goto the ANTLR site; ANTLR is a parser generator;
it generates LL(*) parsers (equivalent to recursive descent); on that site they've
got a couple of grammars available including a Java grammar (if I remember well).

That depends very much on what language the OP knows better. Of course, there are languages, that are designed for parser writing, but VB isn't one of them. (You may be right, if someone knows both equally well, VB might be the better choice, but that's not the point.) Also, in Java the parser will be platform independent, so it can be run on nearly any system.

Yes, I need to use Java but I'd like to see some "simple" implementations before.....I wonder if someone have linked some ".java" class around internet,,,

That ANTLR tool can generate a parser written in Java (one of the main target
languages). Beware though: it isn't "simple".

I used Coco/r but it creates a much complex parser......

Don't expect much simpler from ANTLR; the Java syntax is quite complex and
needs quite a complex parser to recognize it all.
