5 实例：判断闰年

闰年（Leap Year）判断规则：能被4整除但不能被100整除，或者能被400整除

package com.wys.java;

import java.util.Scanner;

public class leapYearDemo {
    public static void main(String[] args) {
        System.out.println("请输入年份：");
        Scanner sc = new Scanner(System.in);
        int year = sc.nextInt();

        //闰年判断规则：能被4整除但不能被100整除，或者能被400整除
        if( (year%4==0)&&(year%100 != 0) || (year%400==0) ){
            System.out.println(year+"是闰年");
        }else{
            System.out.println(year+"不是闰年");
        }
    }
}
