Example 1:

Java

// Java program to demonstrate
// dateYearDay() 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
            // ThaiBuddhistDate Object
            ThaiBuddhistDate hidate
                = ThaiBuddhistDate.now();

            // getting ThaiBuddhistChronology
            // used in ThaiBuddhistDate
            ThaiBuddhistChronology crono
                = hidate.getChronology();

            // getting ThaiBuddhistDate for the
            // given date and year field
            // by using dateYearDay() method
            ThaiBuddhistDate date
                = crono.dateYearDay(
                    ThaiBuddhistEra.BE,
                    2018,
                    24);

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

Output:

ThaiBuddhistDate is: ThaiBuddhist BE 2018-01-24
