The hashCode() method of the ZoneId class in Java is used to return unique hashcode for this ZoneId.
Syntax:
public int hashCode(Object obj)
Parameters: This method accepts nothing.
Return value: This method returns an int which represents the hashCode.
Below programs illustrate the hashCode() method:
Program 1:
// Java program to demonstrate// ZoneId.hashCode() method import java.time.*; public class GFG { public static void main(String[] args) { // create ZoneId object ZoneId zoneId = ZoneId.of("Europe/Paris"); // get and print hashcode System.out.println("hashcode: " + zoneId.hashCode()); }} |
Output:
hashcode: -672549154
Program 2:
// Java program to demonstrate// ZoneId.hashCode() method import java.time.*; public class GFG { public static void main(String[] args) { // create ZoneId object ZoneId zoneId = ZoneId.of("Asia/Calcutta"); // get and print hashcode System.out.println("hashcode: " + zoneId.hashCode()); }} |
Output:
hashcode: -681304890
