ZoneId hashCode() method in Java with Examples

Last Updated : 19 Jun, 2019

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

// 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

// 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
