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
