GregorianCalendar Class hashCode() method

• hashCode() method is available in java.util package.
• hashCode() method is used to returns the hash code for this GregorianCalendar.
• hashCode() method is a non-static method, so it is accessible with the class object and if we try to access the method with the class name then we will get an error.
• hashCode() method does not throw an exception at the time of returning hash code.

Syntax:

    public int hashCode();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of this method is int, it gets hash code value for this GregorianCalendar object.

Example:

// Java program is to demonstrate the example of
// hashCode() method of GregorianCalendar

import java.util.*;

public class HashCodeOfGregorianCalendar {
    public static void main(String args[]) {
        // Instantiating a GregorianCalendar object
        GregorianCalendar ca = (GregorianCalendar) GregorianCalendar.getInstance();

        System.out.println("ca.getTime(): " + ca.getTime());

        // By using hashCode() method is to
        // return the hash code of this GregorianCalendar
        int hc = ca.hashCode();

        // Display hash code of this GregorianCalendar
        System.out.println("ca.hashCode(): " + hc);
    }
}

Output

ca.getTime(): Sat Feb 15 12:13:48 GMT 2020
ca.hashCode(): 1221342502
