What are the differences between super calls and direct calls?

What are the differences between super calls and direct calls?

Super calls and direct calls are both ways to invoke methods in programming, but they have key differences. Super calls refer to calling a method from a parent class, while direct calls invoke a method from the current class.

Can you give me an example of each?

Sure! A direct call would look like this: this.methodName(). A super call would be super.methodName() to call a method from the parent class.

When should I use super calls?

You should use super calls when you want to extend or modify the behavior of a method inherited from a parent class.

Are there any performance differences between them?

Generally, the performance difference is negligible, but super calls may have a slight overhead due to the lookup in the parent class.
