java语言：判断是否是闰年

import java.util.Scanner;

public class LeapYear {
    public static void main(String[] args) {
        Scanner input=new Scanner(System.in);
        System.out.println("请输入年份：");
        int year=input.nextInt();
        if((year%400==0)||(year%4==0)&&(year%100!=0)){
            System.out.println(year+"是闰年");
        }
        else{
            System.out.println(year+"不是闰年");
        }
    }
}
