I just found out the difference between Override and Overload:
Overriding methods have the same method signatures while Overloading methods
have different method signatures.
But what's the deal with Overwrite? Or is there a term "Overwrite" in Java
at all?

overriding是子类对父类method，overloading是同一个类中的method，
hiding是静态系统method

This makes sense. Thank you!
But what about overwriting? Is there such a concept of overwriting method in
Java? How come I see "overwriting" everywhere?

overwriting is not a concept specific to Java or any programming language. I
t simply means "writing new values over old ones".
