Java programming problem, could you please add comments "//" so that I know why you took the steps you did? Thank you!

Write a program that performs long multiplication.

1. Prompt the user for a three digit integer x
2. Prompt the user for a two integer y
3. Compute x multiplied by y using a similar display as follows:

123 13 369 1230 1599 4. Use System.out.printf to format for right alignment. TIP: 123; int a = int b = 13; int c = 369; int d = 1230; System.out.printf("%8d ", a); System.out.printf("%8d ", b); System.out.println(". System.out.printf("%8d ", c); System.out.printf("%8d ", d); ")
