Revising Basic Java Concepts — Question 63
Back to all questionsQuestion 40
Write a program that inputs a number and tests if the given number is a multiple of both 3 and 5.
import java.util.Scanner;
public class KboatMultipleCheck
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter number: ");
int num = in.nextInt();
if (num % 3 == 0 && num % 5 == 0)
System.out.println("Multiple of 3 and 5");
else
System.out.println("Not a multiple of 3 and 5");
}
}Output
