带有示例的Java中的 HijrahDate from() 方法

Java.time.chrono.HijrahDate类的from()方法用于根据特定时间对象的回历系统获取回历日期。

句法：

public static HijrahDate from(
      TemporalAccessor temporal)

参数：此方法采用任何时间访问器的对象，在此基础上将形成 Hijrah 日期。

返回值：该方法根据回历系统返回指定时间对象的回历日期。

以下是说明from()方法的示例：

示例 1：

Java

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

输出：

HijrahDate: Hijrah-umalqura AH 1440-02-16

示例 2：

Java

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

输出：

HijrahDate: Hijrah-umalqura AH 1440-04-23
