Java中的 MinguoDate from() 方法及示例

Java.time.chrono.MinguoDate类的from()方法用于根据特定时间对象的民国日历系统获取民国日期。

句法：

public static MinguoDate from(TemporalAccessor temporal)

参数：此方法获取任何时间访问器的对象，在此基础上将形成民国日期。

返回值：该方法根据民国日历系统返回指定时态对象的民国日期。

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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.from(zonedate);
  
            // Display the result
            System.out.println("MinguoDate: "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

MinguoDate: Minguo ROC 107-10-25

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
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.from(localdate);
  
            // Display the result
            System.out.println("MinguoDate: "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

MinguoDate: Minguo ROC 107-12-30
