Java Program to Check Whether a Number is an Even or Odd
Hello Shouters !! Today we will make a Java Program to Check Whether a Number is an Even or Odd.
What is an Even Or Odd Number?
The number is said to be even if the number is completely divisible by the number 2 which means after division it gives a remainder of 0. An odd number is a number that leaves remainder 1 after division with 2.
1. First Method- Division Method
In this method, we will divide the number by 2 and check if the remainder is 1 or not. Depending on the value we will check the number.

// Division Method - Java Program to Check a Number is an Odd/Even Number import java.util.*; class EvenOdd{ public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.println("Enter the Number you want to Check"); int number = sc.nextInt(); if (number% 2 == 0) System.out.println("Even Number"); else System.out.println("Odd Number"); } } } |
Output – Enter the Number you want to check 24 Even Number
2. Second Method- Using Bitwise Operator
In this method, we will Bitwise And (&) the number with 1 and we will get one only if the number is odd.
Example- The binary code of 9 is 1001 and the binary code of 1 is 1000 we will get 1000 as the output which makes 1 in decimal number.

Output – Enter the Number you want to check 23 Odd Number
So, it is very important to understand the Java Program to Check Whether a number is odd or even.
