kotlin abstract classes

Question

Abstraction

You decide to make the Component class abstract, since you are not going to create objects of that type.
You also add a show() function to it that the derived classes need to override.
For a Button, the show() function should output: "Showing a Button", while for an Image it should output: "Showing an Image".

Answer 1

This is the practice 32.2 in the Kotlin course.

You need to write the concrete implementation of the show function in both subclasses of Component.
override fun show() { ... }

And what is YOUR question?
