Hi Charu,
I hope you got VA working ok. Just an FYI, when you're studying, it's much safer to write and compile your code by hand.
IDE's optimize
alot of code, correcting syntax errors, etc. You may get a clean compile with VA but not with the JDK. As Sun only tests you on what their compiler can do you're much better off using it directly.
