Java输入一个正整数，输出是奇数还是偶数

import java.util.Scanner;

public class Jioushu {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        if(a%2==0){
            System.out.println("偶数");
        }else {
            System.out.println("奇数");
        }

    }
}
