import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing 
            // JapaneseDate Object 
            JapaneseDate hidate = JapaneseDate.now(); 
  
            // getting hash code of the date 
            // by using hashCode() method 
            long tempo = hidate.hashCode(); 
  
            // display the result 
            System.out.println("hashcode:"
                               + tempo); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:"
                               + e);
