Java Program to find Odd or Even number!

Let’s see an interesting program for school/college students who are learning core Java.

To find whether an entered number is Odd or Even is very simple, all you have to do is divide the number by 2 and if you get the remainder 0 (zero) then it is an Even number or it is an Odd number.

Eg: 10 / 2 = 5, here 5 is the quotient, 0 is the remainder.

In Java there are two operators you can use to find quotient and remainder. (/) slash and (%) modulus, where the / will give the quotient and % will give the remainder value. 

So here is the Java Program to find Odd or Even number!

import java.util.Scanner;

public class OddorEven {

    public static void main(String[] args) {
        
        int num;

        Scanner in = new Scanner(System.in);
        System.out.println("Enter a number:");
        
        //get the input value
        num = in.nextInt();

        //if the value of c is 2 then it is a prime number
        //because a prime number should be exactly divisible by 2 times only (itself and 1)
        if ( num % 2 == 0) {            
            System.out.println(num+" is an Even number!");
        } else {
            System.out.println(num+" is an Odd number!");
        }
        
    }
}

Just read the comments in the above program to understand it.

Example Output of the above program:

Enter a number:
15
15 is an Odd number!
