Submitted by Nidhi, on March 10, 2022

Problem statement

In this program, we will read an integer number from the user. Then we will check a given number is EVEN or ODD using bit masking.

Java program to check a given number is EVEN or ODD using bit masking

The source code to check a given number is EVEN or ODD using bit masking is given below. The given program is compiled and executed successfully.

// Java program to check a given number is 
// EVEN or ODD using bit masking

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner SC = new Scanner(System.in);

    int num = 0;

    System.out.printf("Enter Number: ");
    num = SC.nextInt();

    if ((num & 1) == 1)
      System.out.printf("Number is ODD");
    else
      System.out.printf("Number is EVEN");
  }
}

Output

Enter Number: 7
Number is ODD

Explanation

In the above program, we imported the "java.util.Scanner" package to read variable values from the user. And, created a public class Main. It contains a static method main().

The main() method is an entry point for the program. Here, we read an integer number from the user using Scanner class and checked the given number is EVEN or ODD using bit masking and printed appropriate message.
