The statement System.out.println(Hi, I want to execute); will never execute. In less than 5 minutes you can start counting (and solving!) This is because whenever an exception occurs, Javas runtime environment checks the call stack backwards to identify methods that can catch the exception. Normal flow of program can be maintained.
