为什么我运行错了呢
package day02;import java.util.Scanner;
public class Demo2 {
public static void main(String[] args) {
System.out.println("请输入一个年份（例如：2013）：");
Scanner scanner = new Scanner(System.in);
int year = scanner.nextInt();
if (year<0||year>2099){
System.out.println("请输入正确的年份：");
System.exit(0);
}
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");
}
}
