Java UUID: How to Generate a Unique ID

In Java, the method to retrieve a UUID is by using the randomUUID() method from the java.util.UUID class. You can obtain a UUID by using the following code:

import java.util.UUID;

public class Main {
    public static void main(String[] args) {
        UUID uuid = UUID.randomUUID();
        System.out.println(uuid);
    }
}

The code above will generate a random UUID, for example: c2a5b7c3-0e30-4f78-8d84-66cbf5b06e6f.
