例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// 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.of(1398, 03, 23);

        System.out.println("HijrahDate: "
                           + hidate.toString());

        // Checking if the date is leap year or not
        // by using isLeapYear() method
        boolean flag = hidate.isLeapYear();

        // Display the result
        if (flag)
            System.out.println("Leap year");
        else
            System.out.println("Not a leap year");
    }
}

Output:

HijrahDate: Hijrah-umalqura AH 1398-03-23
Not a leap year

例 2:

Java 语言(一种计算机语言，尤用于创建网站)

// 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();

        System.out.println("HijrahDate: "
                           + hidate.toString());

        // Checking if the date is leap year or not
        // by using isLeapYear() method
        boolean flag = hidate.isLeapYear();

        // Display the result
        if (flag)
            System.out.println("Leap year");
        else
            System.out.println("Not a leap year");
    }
}

Output:
