Describe inheritance in Java?

Answer 1

If I extend a class, I am the sub class. The class that I am extending is called the super class. (Terminology)

I am now a smaller part of the super class.
For example, If I am created as my super class, I can be casted to my sub class.

What are some benefits?
If I extend a class, I can now access all non-private members of the super class. If somebody wants to use the super class as a blue print for all sub classes, then I can override methods of the blue print if necessary.

If the way I explained it was a bit confusing, I do suggest reviewing what SoloLearn has in the course they offer. I'm just a meatball afterall.
If you are wondering what the point of it is, here's a practical example of inheritance/OOP.

Oups, that was the wrong link.
Nobody saw that, ok, moving on. 👌😳
