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