Question

Write a Java program to check and print whether a number is multiple of 13 or not​

Answer 1

Answer:

This is the required Java program for the question.

import java.util.*;

public class isMultiple {

   public static void main(String args[])  {

       System.out.print("Enter a number:   ");

       int a=(new Scanner(System.in)).nextInt();

       if(a%13==0)

           System.out.println("Number is multiple of 13.");

       else

           System.out.println("Number is not a multiple of 13.");

   }

}

Explanation:

• A number is said to be a multiple of 13 if it leaves 0 as remainder when divided by 13. So, we have to check if the remainder obtained is 0 or not.
• To calculate remainder, the modulo operator is used. Here, the number is stored in variable 'a'. So, a%13 gives the remainder. To check for equality, the == operator is used. Therefore, the condition becomes - a%13==0. If the condition is true, number is a multiple of 13 else not.

Answer 2

Answer:

Program:-

import java.util.*;

public class Multiple

{

public static void main(String args[ ])

{

Scanner in=new Scanner(System.in);

int n;

System.out.println("Enter the number");

n=in.nextInt();

if(n%13==0)

{

System.out.println("It is a multiple of 13");

}

else

System.out.println("It is not a multiple of 13");

}

}
