Clock Class hashCode() method
- hashCode() method is available in java.time package.
- hashCode() method is used to get the hash code value of this Clock.
- hashCode() method is a non-static method, it is accessible with the class object only 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):
Return value:
The return type of this method is int, it retrieves this Clock hash code value.
Example:
// Java program to demonstrate the example
// of int hashCode() method of Clock
import java.time.*;
public class HashCodeOfClock {
public static void main(String args[]) {
// Instantiates two ZoneId for Accra and Asmara
ZoneId zone_1 = ZoneId.of("Africa/Accra");
ZoneId zone_2 = ZoneId.of("Africa/Asmara");
// Initialize two Clock objects
Clock cl1 = Clock.system(zone_1);
Clock cl2 = Clock.system(zone_2);
// returns the hash code value of this Clock cl1
int cl_hc = cl1.hashCode();
// Display cl1 hash code
System.out.println("cl1.hashCode(): " + cl_hc);
// returns the hash code value of this Clock cl2
cl_hc = cl2.hashCode();
// Display cl2 hash code
System.out.println("cl2.hashCode(): " + cl_hc);
}
}
Output
cl1.hashCode(): 1799826076
cl2.hashCode(): -24907989
