JapaneseDate hashCode() method in Java with Example

  • Last Updated : 24 Apr, 2020

The hashCode() method of java.time.chrono.JapaneseDate class is used to get the hash code for the particular japanese date.

Syntax:

public int hashCode()

Parameter: This method does not accept any argument as a parameter.

Return Value: This method returns the hash code for the particular japanese date.

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



Example 1:




// Java program to demonstrate
// hashCode() 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
            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);
        }
    }
}
Output:
hashcode : -691830052

Example 2:




// Java program to demonstrate
// hashCode() 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
            JapaneseDate hidate
                = JapaneseDate.of(2003, 06, 13);
  
            // 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);
        }
    }
}
Output:
hashcode : -691914148
