JapaneseChronology localDateTime() method in Java with Example

The localDateTime() method of java.time.chrono.JapaneseChronology class is used to retrieve the local date and time according to Japanese calendar system from any other object of temporal accessor.

Syntax:

public ChronoLocalDateTime localDateTime
               (TemporalAccessor temporal)

Parameter: This method takes the object of any temporal accessor as a parameter.

Return Value: This method returns the local date and time according to Japanese calendar system from any other object of the temporal accessor.

Below are the examples to illustrate the localDateTime() method:

Example 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
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();

            // getting JapaneseChronology
            // used in JapaneseDate
            JapaneseChronology crono
                = hidate.getChronology();

            // creating and initializing
            // TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime.parse(
                    "2018-10-25T23:12:31."
                    + "123+02:00[Europe/Paris]");

            // getting JapaneseDate for the
            // given TemporalAccessor object
            // by using localDateTime() method
            ChronoLocalDateTime<JapaneseDate> date
                = crono.localDateTime(zonedate);

            // display the result
            System.out.println("JapaneseDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

Output:

JapaneseDate is: Japanese Heisei 30-10-25T23:12:31.123

            // given TemporalAccessor object
            // by using localDateTime() method
            ChronoLocalDateTime<JapaneseDate> date
                = crono.localDateTime(localdate);

            // display the result
            System.out.println("JapaneseDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

Output:

JapaneseDate is: Japanese Heisei 30-12-30T19:34:50.630
