带有示例的Java中的 HijrahChronology localDateTime() 方法：Set – 2

Java.time.chrono.HijrahChronology类的localDateTime()方法用于根据 Hijrah 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 Hijrah 日历系统从时间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

// 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
            // HijrahDate Object
            HijrahDate hidate
                = HijrahDate.now();
 
            // getting HijrahChronology
            // used in HijrahDate
            HijrahChronology crono
                = hidate.getChronology();
 
            // creating and initializing
            // TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime.parse(
                    "2018-10-25T23:12:31."
                    + "123+02:00[Europe/Paris]");
 
            // getting HijrahDate for the
            // given TemporalAccessor object
            // by using localDateTime() method
            ChronoLocalDateTime date
                = crono.localDateTime(zonedate);
 
            // display the result
            System.out.println("HijrahDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

HijrahDate is: Hijrah-umalqura AH 1440-02-16T23:12:31.123

示例 2：

Java

// 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
            // HijrahDate Object
            HijrahDate hidate = HijrahDate.now();
 
            // getting HijrahChronology
            // used in HijrahDate
            HijrahChronology crono
                = hidate.getChronology();
 
            // creating and initializing
            // TemporalAccessor object
            LocalDateTime localdate
                = LocalDateTime
                      .parse("2018-12-30T19:34:50.63");
 
            // getting HijrahDate for the
            // given TemporalAccessor object
            // by using localDateTime() method
            ChronoLocalDateTime date
                = crono.localDateTime(localdate);
 
            // display the result
            System.out.println("HijrahDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

输出：

HijrahDate is: Hijrah-umalqura AH 1440-04-23T19:34:50.630
