The following example shows the usage of java.util.UUID.compareTo()
package com.tutorialspoint; import java.util.*; public class UUIDDemo { public static void main(String[] args) { // creating UUIDs UUID u1 = UUID.fromString("38400000-8cf0-11bd-b23e-10b96e4ef00d"); UUID u2 = UUID.fromString("38400000-8cf0-11bd-b23e-10b96e4ef00d"); // comparing uuids System.out.println("Comparing two UUIDs: "+u1.compareTo(u2)); } }
Let us compile and run the above program, this will produce the following result.
Comparing two UUIDs: 0
