JapaneseDate from() method in Java with Example

The from() method of java.time.chrono.JapaneseDate class is used to get the Japanese date according to the Japanese calendar system for the particular temporal object.

Syntax:

public static JapaneseDate from(
       TemporalAccessor temporal)

Parameter: This method takes the object of any temporal accessor on the basis of which Japanese date is going to be formed.
Return Value: This method returns the Japanese date according to the Japanese calendar system for the specified temporal object.

Below are the examples to illustrate the from() method:
Example 1:

Java

// Java program to demonstrate from() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {

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

            // Creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
              = JapaneseDate.from(zonedate);

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

Output

JapaneseDate: Japanese Heisei 30-10-25

        }
    }
}

Output
