Classes & Methods Homework

Homework!

As you read through this, notice the new content introduced. We encourage you to do your own research (this can be Google, ChatGPT, documentation, etc.). Here, we introduce the _ property (memory safety), extends keyword, and super() method.

To complete the homework, implement the TODO: comments. The example usage should guide you and work if all implementation is done correctly. Have fun!

If anything simply cannot go wrong, it will anyway.

If you perceive that there are four possible ways in which a procedure can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.

You have no purpose because you fear to seek one. That fear is your failure. Your fear brings you pain. We know pain. Our purpose is its end.
