import java.util.Scanner; public class main { public static void main (String[] args) { Scanner reader = new Scanner(System.in); While (true) { System.out.println("Enter number 1:"); int n1 = reader.nextInt(); System.out.println("Enter number 2:"); int n2 = reader.nextInt(); if (n1 >= 0 && n2 >= 0) { int p = n1 * n2; System.out.println(p); break; } } } } This should do the job. Hope it helps. =)

Use the code I've mentioned above, the while loop will keep looping and asking for both positive input. The loop will only break if both inputs are positive.

hi if you provide 2 negative integers that becomes positive right.
