Java判断是否为闰年的方法示例

import java.util.Scanner; public class LeapYear {   public static void main(String[] arg){     Scanner scan = new Scanner(System.in);     System.out.println("请输入一个年份:");     long year= scan.nextLong();     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!");     }   } }
