Check Even or Odd

Write a Java program to accept a number and check whether the number is even or not. Prints 1 if the number is even or 0 if odd.

Pictorial Presentation:

Sample Solution:

Java Code:

import java.util.*;

public class Exercise49 {
    public static void main(String[] args) {
        // Create a scanner for user input
        Scanner in = new Scanner(System.in);
        
        // Prompt the user to input a number
        System.out.print("Input a number: ");
        int n = in.nextInt();
        
        // Check if the number is even and print the result
        if (n % 2 == 0) {
            System.out.println(1); // If the number is even, print 1
        } else {
            System.out.println(0); // If the number is odd, print 0
        }
    }
}

Sample Output:

Input a number: 20
