JapaneseChronology zonedDateTime(TemporalAccessor) method in Java with Example

The zonedDateTime() method of java.time.chrono.JapaneseChronology class is used get the zonal date and time according to Japanese calendar system from the another TemporalAccessor object.

Syntax:

public ZonedDateTime zonedDateTime(
          TemporalAccessor temporal)

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

Return Value: This method returns the ZonedDateTime according to the Japanese calendar system from another TemporalAccessor object.

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

Example 1:

// Java program to demonstrate
// zonedDateTime() 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 and time for the
            // given TemporalAccessor object
            // by using zonedDateTime() method
            ChronoZonedDateTime<JapaneseDate> date
                = crono.zonedDateTime(zonedate);

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

Output:

JapaneseDate and time is:
 Japanese Heisei 30-10-25T23:12:31.123+02:00[Europe/Paris]

Example 2:

// Java program to demonstrate
// zonedDateTime() method

import java.util.*;

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
            LocalDateTime localdate
                = LocalDateTime.parse(
                    "2018-12-30T19:34:50.63");

            // getting JapaneseDate and time for the
            // given TemporalAccessor object
            // by using zonedDateTime() method
            ChronoZonedDateTime<JapaneseDate> date
                = crono.zonedDateTime(localdate);

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

Output:

passed parameter can not form a date
Exception thrown:
 java.time.DateTimeException:
 Unable to obtain ChronoZonedDateTime from TemporalAccessor:
 class java.time.LocalDateTime
