package day01;

import java.util.Scanner;

public class leap_year {
    public static void main (String[] args) {
        
        System.out.println("亲输入年份，闰年输出true，否则输出false。输入 0 退出。 ");
        Scanner scanner1 = new Scanner(System.in);
        int year = scanner1.nextInt();
        for(;;) {
        if (year == 0) {
            System.out.println("已退出！");
            break;};
        
        boolean isLeapYear = (year % 4 == 0 && year % 100 !=0 )||year % 400 == 0;
        System.out.println(isLeapYear);
        year = scanner1.nextInt();
        }
        scanner1.close();
