Write a Java Program to Check Whether a Number is Even or Odd

In Java programming, checking whether a number is even or odd is a fundamental task.

In this tutorial, we’ll show you how to write a simple Java program to determine if a given number is even or odd.

To check if a number is even or odd, we use the modulo operator (%).

The modulo operator gives us the remainder when one number is divided by another.

If the remainder is 0, then the number is even; otherwise, it’s odd.

Here’s the Java program to check whether a number is even or odd:

import java.util.Scanner;

public class EvenOrOdd {
   public static void main(String[] args) {
      Scanner scanner = new Scanner(System.in);
      System.out.print("Enter a number: ");
      int number = scanner.nextInt();
      
      if (number % 2 == 0) {
         System.out.println(number + " is even");
      } else {
         System.out.println(number + " is odd");
      }
      
      scanner.close();
   }
}

Let’s break down the code:

  • We first import the Scanner class to get input from the user.
  • We create a new Scanner object and prompt the user to enter a number.
  • We read the input from the user and store it in the variable number.
  • We use the if statement to check if the number is even or odd.
  • If the number is even, we print a message saying so. Otherwise, we print a message saying the number is odd.
  • We close the scanner to free up resources.

To test the program, compile and run it. When prompted, enter a number and press enter.

The program will then tell you if the number is even or odd.

In conclusion, checking whether a number is even or odd is a simple task in Java programming.

We use the modulo operator to determine if a number is even or odd, and then we print out the result.

The program we wrote above is a basic example of how to do this, but it can be modified to suit more complex requirements.
