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!"); 
    } 
  } 
}
