带有示例的Java中的 HijrahChronology date() 方法：Set – 2

Java.time.chrono.HijrahChronology类的date()方法用于根据 Hijrah 日历系统从另一个 TemporalAccessor 对象中获取本地日期。

句法：

public HijrahDate date(TemporalAccessor temporal)

参数：此方法将任何时间访问器的对象作为参数。

返回值：此方法根据回历系统从另一个 TemporalAccessor 对象返回本地日期。

以下是说明date()方法的示例：

示例 1：

// Java program to demonstrate
// date() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing  HijrahDate Object
            HijrahDate hidate = HijrahDate.now();
  
            // getting HijrahChronology used in HijrahDate
            HijrahChronology crono = hidate.getChronology();
  
            // creating and initializing TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime.parse(
                    "2018-10-25T23:12:31."
                    + "123+02:00[Europe/Paris]");
  
            // getting HijrahDate for the
            // given TemporalAccessor object
            // by using date() method
            HijrahDate date = crono.date(zonedate);
  
            // display the result
            System.out.println("HijrahDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

HijrahDate is: Hijrah-umalqura AH 1440-02-16

示例 2：

// Java program to demonstrate
// date() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing  HijrahDate Object
            HijrahDate hidate = HijrahDate.now();
  
            // getting HijrahChronology used in HijrahDate
            HijrahChronology crono = hidate.getChronology();
  
            // creating and initializing TemporalAccessor object
            LocalDateTime localdate
                = LocalDateTime
                      .parse("2018-12-30T19:34:50.63");
  
            // getting HijrahDate for the
            // given TemporalAccessor object
            // by using date() method
            HijrahDate date = crono.date(localdate);
  
            // display the result
            System.out.println("HijrahDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

HijrahDate is: Hijrah-umalqura AH 1440-04-23
