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
