Java 中的 Japanese 年表 zonedDateTime(临时访问器)方法，示例

原文:https://www . geeksforgeeks . org/Japanese 年表-zoneddatemetemporalacessor-Java 中的方法-带示例/

Java . time . chrono . Japanese 年表类的 zonedDateTime() 方法用于从另一个 TemporalAccessor 对象获取根据日本日历系统的区域日期和时间。

语法:

public ZonedDateTime zonedDateTime(
          TemporalAccessor temporal)

参数:该方法以任意时态取值器的对象为参数。

返回值:该方法从另一个临时处理器对象返回根据日本日历系统的区域时间。

以下是说明区域时间()方法的示例:

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
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();

            // getting JapaneseChronology
            // used in JapaneseDate
            JapaneseChronology crono
                = hidate.getChronology();

            // creating and initializing
            // TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime
                      .parse(
                          "2018-10-25T23:12:31."
                          + "123+02:00[Europe/Paris]");

            // getting JapaneseDate and time for the
            // given TemporalAccessor object
            // by using zonedDateTime() method
            ChronoZonedDateTime<JapaneseDate> date
                = crono.zonedDateTime(zonedate);

            // display the result
            System.out.println(
                "JapaneseDate 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:

JapaneseDate and time is:
 Japanese Heisei 30-10-25T23:12:31.123+02:00[Europe/Paris]

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
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();

            // getting JapaneseChronology
            // used in JapaneseDate
            JapaneseChronology crono
                = hidate.getChronology();

            // creating and initializing
            // TemporalAccessor object
            LocalDateTime localdate
                = LocalDateTime.parse(
                    "2018-12-30T19:34:50.63");

            // getting JapaneseDate and time for the
            // given TemporalAccessor object
            // by using zonedDateTime() method
            ChronoZonedDateTime<JapaneseDate> date
                = crono.zonedDateTime(localdate);

            // display the result
            System.out.println(
                "JapaneseDate 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
