Java中的 MinguoChronology localDateTime() 方法与示例

Java.time.chrono.MinguoChronology类的localDateTime()方法用于根据民国日历系统从时间访问器的任何其他对象中检索本地日期和时间。

句法：

public ChronoLocalDateTime 
    localDateTime(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：此方法根据民国日历系统从临时访问器的任何其他对象返回本地日期和时间。

以下是说明localDateTime()方法的示例：

示例 1：

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

输出：

MinguoDate is: Minguo ROC 107-10-25T23:12:31.123

示例 2：

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

输出：

MinguoDate is: Minguo ROC 107-12-30T19:34:50.630
