编写程序，判断给定的某个年份是否是闰年。

import java.util.*;
public class Bissextile{
    public static void main(String[]arge){
        System.out.println("please input the nian:");
    int year;
    Scanner scanner = new Scanner(System.in);
    year = scanner.nextInt();
    if(year<0||year>3000){
        System.out.println("the Year is wrong,exit!");
        System.exit(0);
    }
    if((year%4==0)&&(year%100!=0)||(year%400==0))
        System.out.println(year+"is bissextile");
    else
        System.out.println(year+"is not bissextile");
    }    
}
