下麵是說明isLeapYear()方法的示例：

範例1：

// Java program to demonstrate 
// isLeapYear() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing HijrahDate Object 
        HijrahDate hidate = HijrahDate.now(); 
  
        // getting HijrahChronology used in HijrahDate 
        HijrahChronology crono = hidate.getChronology(); 
  
        // getting id of this Chronology 
        // by using isLeapYear() method 
        boolean flag = crono.isLeapYear(1444); 
  
        // display the result 
        if (flag) 
            System.out.println("this is leap year"); 
        else
            System.out.println("this is non leap year"); 
    } 
}

輸出：

this is non leap year

範例2：

// Java program to demonstrate 
// isLeapYear() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing  HijrahDate Object 
        HijrahDate hidate = HijrahDate.now(); 
  
        // getting HijrahChronology used in HijrahDate 
        HijrahChronology crono = hidate.getChronology(); 
  
        // getting id of this Chronology 
        // by using isLeapYear() method 
        boolean flag = crono.isLeapYear(1200); 
  
        // display the result 
        if (flag) 
            System.out.println("this is leap year"); 
        else
            System.out.println("this is non leap year"); 
    } 
}

輸出：

this is non leap year
