Question

JAVA Programming

1. Write a program to input a number and check that number is divisible by 7 or

not.​

Answer 1

Answer:

The given program is written in Java.

import java.util.*;

public class IsDivisible    {

   public static void main(String args[])  {

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

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

       if(n%7==0)

           System.out.println("Number is divisible by 7.");

       else

           System.out.println("Number is not divisible by 7.");

   }

}

Explanation:

• To find the remainder obtained when a number is divided by another number, the modulus (%) operator is used.
• So, to get the remainder obtained when a number, say n is divided by 7, we can write - n%7
• If number is completely divisible by 7, then n%7 must be equal to zero.
• So, take the number as input, check if n%7==0. If true, number is divisible by 7 else not.

Answer 2

Answer:

Program:-

import java.io.*;

public class Divisibility

{

public static void main(String args[ ]) throws IOException

{

InputStreamReader read=new InputStreamReader(System.in);

BufferedReader in=new BufferedReader(System.in);

int n,num=0;

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

n=Integer.parseInt(in.readLine());

num=n;

if(n%7==0)

{

System.out.println(num + " is divisible by 7");

}

else

System.out.println(num + " is not divisible by 7");

}

}
