If-else statement, read input from keyboard (by java.util.Scanner) and Find if a number is Even Or Odd example in Java

this example explains three important topics of Java
1. read input from keyboard
2. if-else statement
3. calculate if the number is even or odd

import java.util.Scanner;

public class FindEvenOrOddNumber {

        public static void main(String[] args) {

        // main() function

        Scanner keyboard = new Scanner(System.in);

        // Scanner object to read input from keyboard

        System.out.println("enter an integer");

        int even_odd = keyboard.nextInt();

         if(even_odd%2 == 0) //check if number is odd or even

                                System.out.println(even_odd + " is even number.");

                         else

                                System.out.println(even_odd + " is odd number.");

}

}
