import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class EvenNumber{

    public static void main(String args[]) throws IOException {

    Sys tem.out.println("Enter the number");
       int num= 0;
         BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
         String data = br.readLine();

           num = Integer.parseInt(data);
               if((num %2)==0){
                   System.out.println("Number is Even");

               } else{

                   System.out.println("Number is Odd");

                   }
               }
             }

Description: num is variable which hold the inputted number. BufferReader is used for inputting number. Even numbers are those numbers, which are divisible by 2, and odd numbers are not divisible by 2. if((num %2)==0) is checking the condition of num divisibility. If divisible then it will print even number else odd number.
