Generate random Id using java inbuilt UUID object

Using java inbuilt UUID object here we are going to print 5 unique ids.  Using this approach it is guaranteed that every time java compiler will print the new and unique id.

import java.util.UUID;

public class GenerateId {
    public static void main(String[] args) {
       
        for (int i = 0; i < 5; i++){
            String generatedID = UUID.randomUUID().toString();
            System.out.println(generatedID);
        }
    }
}


Output:
