MinguoChronology zonedDateTime(Instant, ZoneId) Java中的方法

Java.time.chrono.MinguoChronology类的zonedDateTime()方法用于根据民国日历从特定时刻检索特定区域的日期和时间。

句法：

public ZonedDateTime zonedDateTime(
       Instant instant, ZoneId zone)

参数：此方法将以下参数作为参数。

• 瞬间：这是瞬间类型的对象
• zone：这是 zoneId 类型的对象

返回值：该方法根据民国日历从特定时刻返回特定区域的ZonedDateTime 。

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();
  
            // getting MinguoDate and time for the
            // given Instant and ZoneId
            // by using zonedDateTime() method
            ChronoZonedDateTime date
                = crono.zonedDateTime(
                    Instant.now(),
                    ZoneId.systemDefault());
  
            // 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 109-04-20T14:24:49.696Z[Etc/UTC]

        }
    }
}

输出：

MinguoDate and time is: Minguo ROC 59-01-01T06:56:40Z[Etc/UTC]
