Question

I’m looking for bad examples of using inheritance. I’m not very creative so this was the best I could think of:

class Car : public Engine {}

A car has an engine, but it is not an engine.

This would probably work to explain the concept, but I believe there are more illustrative examples?

Answer 1

The “classic” example ;-):

public class Stack extends Vector { 
    ...
}

A Stack is NOT a Vector.

If Stack extends Vector, you are able to insert/delete at every given index, whereas you should only be allowed to add/delete elements by pushing/popping.
