Is there anyone who understands Use Case Diagrams in Java?

by

I have created Use Case Diagram for my java project at school, but I am not sure if it is the right way.
Could someone help me, please?

It is an application that gives user questions, he can tick some answers (multiple choice with multiple answers) and then see the success rate.

Thanks
