What is displayed by out.println(num)? Is num a String of numeric characters or ?
Should your code test for num == null?
What is the error message?

Before calling parseInt() method, you better check whether the value is null, since this method would throws a NPE.

It would be easy for us, if you had pasted the error message here.

I given condition for checking null value. Now my program is running well.
