[antlr-interest] Java 1.5 grammar updated

[Diane Nkonyereza]

That's strange. I can't compile such a file, I get error : 'class' or 'interface' expected.

This is the same as the grammar rule in the Java spec at:
http://java.sun.com/docs/books/jls/second_edition/html/syntax.doc.html



I was surprised by this, and being curious, I just successfully
compiled a Java source file containing only a single semicolon. It
seems a bit  pointless to me, but it is valid Java! 



All the best

  Hi all,

  

I have a question on the latest Java grammar. The question is related
to the typeDeclaration rule.

  

- What is the ';' in the typeDeclaration Rule? Can someone please gives
me an example of when the ';' could be an option or is it possible to
just have ';' in java file and compile it successfully?

   

  typeDeclaration
    :   classOrInterfaceDeclaration
    |   ';'
    ;
Regards,

Diane.
