Parameters: The method does not take any parameters.
Return Value: The method returns the hash code value for this calendar object..
Below programs illustrate the working of hashCode() Method of Calendar class:
Example 1:
Java
// Java code to illustrate// hashCode() methodimport java.util.*;public class Calendar_Demo { public static void main(String args[]) { // Creating a calendar object Calendar calndr = Calendar.getInstance(); // Displaying the current calendar System.out.println("The time on" + " Calendar shows: " + calndr.getTime()); // Getting the hash code int hash_code = calndr.hashCode(); System.out.println("The hash code " + "for this calendar is: " + hash_code); }} |
Output:
The time on Calendar shows: Wed Feb 20 15:55:22 UTC 2019 The hash code for this calendar is: 194416203
Example 2:
Java
// Java code to illustrate// hashCode() methodimport java.util.*;public class Calendar_Demo { public static void main(String args[]) { // Creating a calendar Calendar calndr = new GregorianCalendar(2018, 6, 10); // Displaying the current calendar System.out.println("The time on" + " Calendar shows: " + calndr.getTime()); // Getting the hash code int hash_code = calndr.hashCode(); System.out.println("The hash code " + "for this calendar is: " + hash_code); }} |
Output:
The time on Calendar shows: Tue Jul 10 00:00:00 UTC 2018 The hash code for this calendar is: -2123101761
