Question

Write a Java program that first reads a positive integer from the user - let's call it howMany. Then the program reads howMany pairs of integers - let's call them n1 and n2. For each pair, the program determines if the first component in the pair is a multiple of the second component, in other words, if n1 is a multiple of n2. For example, if numberOfPair is 5, your program will read 5 pairs of integers, and for each pair (n1, n2) it will decide if n1 is a multiple of n2.

Answer 1

import java.util.Scanner;

public class CheckPairMultiple {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter how many pairs: ");
        int howMany = in.nextInt();
        for (int i = 0; i < howMany; i++) {
            System.out.print("Enter two numbers: ");
            int n1 = in.nextInt(), n2 = in.nextInt();
            if (n1 % n2 == 0) {
                System.out.println(n1 + " is a multiple of " + n2);
            } else {
                System.out.println(n1 + " is not a multiple of " + n2);
            }
        }
    }
}
