How do I terminate my program when more input is entered than required?

Question

I am required to write a program that adds two numbers. It also requires us to display an error message and terminate the program when more than two numbers are entered by the user. I am a beginner and thus I am having trouble in constructing an IF statement that can terminate the program when more than two integers are entered by the user. For instance in the output:

Please enter two numbers for addition:
2 2 3
Error! System terminating

So how do i make that error message to appear and terminate the program when the user enters more than two integers?

Thanks!

Shouldn't it be System.exit(0)? See link [http://stackoverflow.com/questions/22452930/terminating-java-program](Terminate program) – Vaulstein Apr 22 '15 at 11:57
we need to pass an int, you can pass any value. – Saurabh Jhunjhunwala Apr 22 '15 at 11:57
