UUID hashCode() Method in Java with Examples
The hashCode() method of UUID class in Java is generally used to get the hash code value of the UUID.
Syntax:
public int hashCode()
Parameters: This method does not take any parameter.
Return Value: This method returns an integer value which is the hashCode value for this UUID instance.
Below programs illustrate the working of hashCode() method:
Program 1:
// Java code to illustrate hashCode() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Creating two UUIDs UUID UUID_1 = UUID .fromString( "58e0a7d7-eebc-11d8-9669-0800200c9a66"); // Displaying the UUID System.out.println("UUID: " + UUID_1); // Displaying the hashCode value System.out.println("The hashCode value is: " + UUID_1.hashCode()); }} |
Output:
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The hashCode value is: 3744873
Program 2:
// Java code to illustrate hashCode() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Creating two UUIDs UUID UUID_1 = UUID .fromString( "5fc03087-d265-11e7-b8c6-83e29cd24f4c"); // Displaying the UUID System.out.println("UUID: " + UUID_1); // Displaying the hashCode Value System.out.println("The hashCode value is: " + UUID_1.hashCode()); }} |
Output:
UUID: 5fc03087-d265-11e7-b8c6-83e29cd24f4c The hashCode value is: -1447957042
