Java中的MinuoChronology zonedDateTime(TemporalAccessor)方法

Java.time.chrono.MinguoChronology 类的zonedDateTime()方法用于根据民国日历系统从另一个 TemporalAccessor 对象获取分区日期和时间。

句法：

public ZonedDateTime zonedDateTime(
          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：该方法根据民国日历系统从另一个 TemporalAccessor 对象返回分区日期和时间。

下面是说明zonedDateTime()方法的示例：

示例 1：

// 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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting MinguoChronology
            // used in MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // creating and initializing
            // TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime
                      .parse(
                          "2018-10-25T23:12:31."
                          + "123+02:00[Europe/Paris]");
  
            // getting MinguoDate and time for the
            // given TemporalAccessor object
            // by using zonedDateTime() method
            ChronoZonedDateTime date
                = crono.zonedDateTime(zonedate);
  
            // display the result
            System.out.println(
                "MinguoDate 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：

MinguoDate and time is:
 Minguo ROC 107-10-25T23:12:31.123+02:00[Europe/Paris]

示例 2：

// 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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting MinguoChronology
            // used in MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // creating and initializing
            // TemporalAccessor object
            LocalDateTime localdate
                = LocalDateTime.parse(
                    "2018-12-30T19:34:50.63");
  
            // getting MinguoDate and time for the
            // given TemporalAccessor object
            // by using zonedDateTime() method
            ChronoZonedDateTime date
                = crono.zonedDateTime(localdate);
  
            // display the result
            System.out.println(
                "MinguoDate 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
