Java的HijrahChronology zonedDateTime(TemporalAccessor) 方法和示例

Java.time.chrono.HijrahChronology类的zonedDateTime()方法用于根据 Hijrah 日历系统从另一个 TemporalAccessor 对象获取区域日期和时间。

句法：

public ChronoZonedDateTime zonedDateTime(TemporalAccessor temporal)

Parameter ：此方法将任何临时访问器的对象作为参数。
返回值：此方法根据来自另一个 TemporalAccessor 对象的 Hijrah 日历系统返回区域日期和时间。
下面是说明zonedDateTime()方法的示例：

示例 1：

Java

// Java program to demonstrate
// zonedDateTime() 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 and time for the
      // given TemporalAccessor object
      // by using zonedDateTime() method
      ChronoZonedDateTime date
        = crono.zonedDateTime(zonedate);
 
      // display the result
      System.out.println("HijrahDate and time is: "
                         + date);
    } catch (DateTimeException e) {
      System.out.println("passed parameter can"
                         + " not form a date");
      System.out.println("Exception thrown: " + e);
    }
  }
}

输出

HijrahDate and time is: Hijrah-umalqura AH 1440-02-16T23:12:31.123+02:00[Europe/Paris]

示例 2：

Java

// Java program to demonstrate
// zonedDateTime() 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 and time for the
      // given TemporalAccessor object
      // by using zonedDateTime() method
      ChronoZonedDateTime date
        = crono.zonedDateTime(localdate);
 
      // display the result
      System.out.println("HijrahDate and time is: "
                         + date);
    } catch (DateTimeException e) {
      System.out.println("passed parameter can"
                         + " not form a date");
      System.out.println("Exception thrown: " + e);
    }
  }
}

输出：

passed parameter can not form a date

Exception thrown: java.time.DateTimeException: Unable to obtain ChronoZonedDateTime from TemporalAccessor: class java.time.LocalDateTime
