Java EBNF?

1149

+2 Q:

Does anyone know of an accurate source for an (E)BNF for the Java language? Preferably, it would be from an authorative source, e.g. Sun.

Thanks.

+2 A:

First google result :)
Though I can't speak for how up-to-date it might be.

That's for Java 1.2, so it doesn't have generics, assertions, enhanced for-loops, etc.

J Cooper: Wow, you're better at googling than me! I tried, but couldn't find anything.

'java grammar specification' did the trick. Have fun!

True, but at the time I didn't have enough points to comment things.

I'm not sure what you want the spec for, but you may be interested to know that:

the parser in Javac is hand written. No parser generated tools.
there exists a number of repositories for popular parser generators grammars. Here is JavaCC and ANTLR.
