Write a Java program to accept a number and check the number is even or not

import java.util.*;
 public class Exercise49 {
     public static void main(String[] args){
	 Scanner in = new Scanner(System.in);
	 System.out.print("Input a number: ");
     int n = in.nextInt(); 
            if (n % 2 == 0) {
                System.out.println(1); 
               }
			else {
                System.out.println(0); 
              }
     }
}

Sample Output:

Input a number: 20
