JapaneseDate atTime() method in Java with Example

The atTime() method of java.time.chrono.JapaneseDate class is used to add up this JapaneseDate time with a local time for producing an equivalent date and time .

Syntax:

public final ChronoLocalDateTime
      atTime(LocalTime localTime)

Parameter: This method takes the object of type LocalTime as a parameter.
Return Value: This method returns the Chrono local date time by adding up this japanese date with the passed local time.

Below are the examples to illustrate the atTime() method:
Example 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
            // JapaneseDate Object
            JapaneseDate hidate
              = JapaneseDate.now();

            // creating and initializing
            // TemporalAccessor object
            LocalTime localtime
              = LocalTime.now();

            // getting Chrono Local date time
            // by using atTime() method
            ChronoLocalDateTime<JapaneseDate> 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);
        }
    }
}

Output

Chrono LocalDateTime is: Japanese Heisei 32-03-18T17:18:51.528

            // creating and initializing
            // TemporalAccessor object
            LocalTime localtime
              = LocalTime.of(8, 20);

            // getting Chrono Local date time
            // by using atTime() method
            ChronoLocalDateTime<JapaneseDate> 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);
        }
    }
}

Output

Chrono LocalDateTime is: Japanese Heisei 32-03-18T08:20
