The hashCode() method of Java Date class returns a value which is a hash code for this object.
Syntax:
public int hashCode()
Parameters: The function does not accept any parameter.
Return Value: It returns a hashCode value for this object.
Exception: The function does not throws any exception.
Program below demonstrates the above mentioned function:
// Java code to demonstrate// hashCode() function of Date class  import java.util.Date;import java.util.Calendar;public class GfG {    // main method    public static void main(String[] args)    {          // creating a Calendar object        Calendar c1 = Calendar.getInstance();          // set Month        // MONTH starts with 0 i.e. ( 0 - Jan)        c1.set(Calendar.MONTH, 11);          // set Date        c1.set(Calendar.DATE, 05);          // set Year        c1.set(Calendar.YEAR, 1996);          // creating a date object with specified time.        Date dateOne = c1.getTime();          System.out.println("Date: " + dateOne);          // Prints hash Code        System.out.println("HashCode: "                           + dateOne.hashCode());    }} |
Output:
Date: Thu Dec 05 08:22:04 UTC 1996 HashCode: -629399711

Output:
