Check out the JLS for labels, break, and continue

Because a label must be used with a loop and "l2" is set before a variable declaration not a loop.
Make this change to compile:

1.4? Can you type "java -version" and let me know what you get.

I'm using 1.4.2-b28.

Hang on! Do you mean you no longer get a compilation error? Or do you mean when it runs you get the same result?
