Java中的 HijrahChronology isLeapYear() 方法示例

Java.time.chrono.HijrahChronology类的isLeapYear()方法用于区分闰年和非闰年。如果是闰年,则返回 true,否则返回 false。

句法:

public boolean isLeapYear(long prolepticYear)

参数:此方法以prolepticYear作为参数,用于检查是否为闰年。

返回值:如果预测年是闰年,则此方法返回布尔值true,否则返回 false。

注意:传统的伊斯兰回历没有闰年。

下面是说明isLeapYear()方法的示例:

示例 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");
    }
}
输出:
this is non leap year

示例 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");
    }
}
输出:
this is non leap year
