带有示例的Java中的 HijrahDate isLeapYear() 方法

Java.time.chrono.HijrahDate类的isLeapYear()方法用于区分闰年和非闰年。如果此 HijrahDate 表示的年份是闰年,则此方法将返回 true,否则返回 false。

句法:

public boolean isLeapYear()

参数:此方法不接受任何参数作为参数。

返回值:此方法返回布尔值,即如果预测年是闰年则为真,否则为假。

下面是说明isLeapYear()方法的示例:

示例 1:

Java
// 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");
    }
}


Java
// 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");
    }
}


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

示例 2:

Java

// 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");
    }
}
输出:
HijrahDate: Hijrah-umalqura AH 1441-06-25
Leap year
