Java Program to Check Whether a Number is Even or Odd

In this program, you will learn to check whether a number is Even or Odd in Java. To understand this program you should have basic knowledge of if…else statements and ternary operators in java.

Here, we use a java.lang.Scanner object to read a number from the user’s keyboard. The entered number is then stored in a variable number. Now, to check whether the number is even or odd, we find its remainder using % operator and check if it is divisible by 2 or not.

Example-1. Check whether a number is even or odd using the if…else statement

package com.javacodepoint.basics;

import java.util.Scanner;

public class CheckOddEven {

	public static void main(String[] args) {

		// Create scanner object to read user input
		Scanner sc = new Scanner(System.in);

		System.out.println("Enter an integer number: ");
		int number = sc.nextInt();

		// Check whether Odd or Even
		// if number is divisible by 2 completely, then it is Even otherwise Odd
		if (number % 2 == 0) {
			System.out.println("Given number " + number + " is an Even number.");
		} else {
			System.out.println("Given number " + number + " is an Odd number.");
		}

	}

}

OUTPUT-1:

Enter an integer number:
7
Given number 7 is an Odd number.

OUTPUT-2:

Enter an integer number:
4
Given number 4 is an Even number.

Example-2. Check whether a number is even or odd using the ternary operator

package com.javacodepoint.basics;

import java.util.Scanner;

public class CheckOddEven2 {

	public static void main(String[] args) {

		// Create scanner object to read user input
		Scanner sc = new Scanner(System.in);

		System.out.println("Enter an integer number: ");
		int number = sc.nextInt();

		// Check Odd or Even using ternary operator
		String result = (number % 2 == 0) ? "Even number." : "Odd number.";

		// Print the result
		System.out.println("Given number " + number + " is an " + result);
	}

}

OUTPUT-1:

Enter an integer number:
5
Given number 5 is an Odd number.

OUTPUT-2:

Enter an integer number:
20
Given number 20 is an Even number.
