Java的HijrahDate atTime() 方法和示例

Java.time.chrono.HijrahDate类的atTime()方法用于将此 HijrahDate 时间与本地时间相加，以生成等效的日期和时间。

句法：

public final ChronoLocalDateTime atTime(LocalTime localTime)

Parameter ：此方法将LocalTime 类型的对象作为参数。
返回值：此方法通过将此回历日期与传递的本地时间相加来返回 Chrono 本地日期时间。
下面是说明atTime()方法的示例：

示例 1：

Java

// Java program to demonstrate
// atTime() 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();
 
      // creating and initializing
      // TemporalAccessor object
      LocalTime localtime = LocalTime.now();
 
      // getting Chrono Local date time
      // by using atTime() method
      ChronoLocalDateTime date
        = hidate.atTime(localtime);
 
      // display the result
      System.out.println("Chrono LocalDateTime is: "
                         + date);
    } catch (DateTimeException e) {
      System.out.println("passed parameter can"
                         + " not form a date");
      System.out.println("Exception thrown: " + e);
    }
  }
}

输出

Chrono LocalDateTime is: Hijrah-umalqura AH 1441-06-17T07:14:43.879

示例 2：

Java

// Java program to demonstrate
// atTime() 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();
 
      // creating and initializing
      // TemporalAccessor object
      LocalTime localtime = LocalTime.of(8, 20);
 
      // getting Chrono Local date time
      // by using atTime() method
      ChronoLocalDateTime date
        = hidate.atTime(localtime);
 
      // display the result
      System.out.println("Chrono LocalDateTime is: "
                         + date);
    } catch (DateTimeException e) {
      System.out.println("passed parameter can"
                         + " not form a date");
      System.out.println("Exception thrown: " + e);
    }
  }
}

输出

Chrono LocalDateTime is: Hijrah-umalqura AH 1441-06-17T08:20
