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 // 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 // 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 Comment More infoAdvertise with us Next Article UUID hashCode() Method in Java with Examples C chinmoy lenka Follow Improve Article Tags : Misc Java Java - util package Java-Functions Java-UUID +1 More Practice Tags : JavaMisc Similar Reads Period hashCode() method in Java with Examples The hashCode() method of Period class in Java is used to get the generated hashCode for this period.
