All right, so now we're done with the object oriented programming chapter in this chapter, you have
seen what object oriented programming is, how classes and objects work, how to create objects of classes,
how to create instances pretty much of classes then what members of classes are.
Then we have seen how to use interfaces, how to use inheritance, how to also use data classes and
what scope is.
All right.
So these are going to be very important fundamentals that you will need throughout the next chapter.
So we are going to use all of them at one point or at many points, depending on which specific topic
we are looking at.
And many of the things that we have learned are going to happen in the background.
So many of the functionality that we have seen is actually used already quite a bit by Android itself
or better set by the different classes that there are already when it comes to Android development.
And we are using quite some of them.
So we are constantly already using inheritance because we are using the app activity in our main activity.
So we're inheriting from it.
And you will recognize more and more of those things once we get to developing more complex applications.
OK, so thanks a lot for being with me.
And let's get to the next chapter.
See you there.
