Example 1:
Java
// Java program to demonstrate of() 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            // JapaneseDate Object            // By using of() method            JapaneseDate hidate                = JapaneseDate.of(                    JapaneseEra.HEISEI,                    2008, 04, 24);              // 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 2008-04-24
