public class KboatBuzzCheck
{
    public static void buzzNumCheck(int a, int b) {
        int p =  a * b;
        System.out.println("Product = " + p);
        if (p % 10 == 7 || p % 7 == 0)
            System.out.println("Product is a Buzz Number");
        else
            System.out.println("Product is not a Buzz Number");
