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");
}
}
