On what line number?

wherever i start a new method....on that line i get an illegal start of expression error & ';' expected.....m also facing the same problem in many other programs of applets.
Plz help me out. Thnx a ton

You are missing the closing bracket on your main method (should be on line 14). You can't start a new method inside another method, not even the main method.

    }

here is the new formatted code.....now it doesn't show any error....but on running it gives no output.
