    Here the Simplest way :-

    import java.io.; import java.util.;

    public class Solution {

    public static void main(String[] args) {
    int a,b;
    Scanner sc=new Scanner(System.in);
    a=sc.nextInt();
    b=sc.nextInt();
    if(a>0 && b>0)
    {
        System.out.println(a*b);
    }
    else
        System.out.println("java.lang.Exception: Breadth and height must be positive");
}

    }
