00:00:00,150 --> 00:00:05,250
Welcome back in this chapter, we are going to look at object oriented programming, so we're going

2
00:00:05,250 --> 00:00:11,730
to see the importance of object oriented programming, why it is used and then we're going to look into

3
00:00:11,760 --> 00:00:12,480
how to use it.

4
00:00:12,480 --> 00:00:17,310
So we're going to see how to use the different members, what members are.

5
00:00:17,490 --> 00:00:24,990
Then we're going to also see what inheritance is and why inheritance is so useful because we can reuse

6
00:00:24,990 --> 00:00:28,650
quite a bit of code, we can extend functionality.

7
00:00:28,650 --> 00:00:34,110
And that is super powerful, very useful when it comes to more complex applications, when it comes

8
00:00:34,110 --> 00:00:41,730
to in general, working together with other programmers or even using code that you can find online

9
00:00:42,060 --> 00:00:43,650
from third party libraries.

10
00:00:44,040 --> 00:00:44,460
All right.

11
00:00:44,460 --> 00:00:47,360
So this is just the beginning of object oriented programming.

12
00:00:47,370 --> 00:00:50,070
We're going to see what classes and objects are.

13
00:00:50,250 --> 00:00:52,140
How to use interfaces.

14
00:00:52,410 --> 00:00:53,730
What scope is.

15
00:00:53,970 --> 00:00:57,330
And we're also going to look at data classes and a lot more.

16
00:00:57,540 --> 00:01:00,090
So I hope you enjoy this chapter.

17
00:01:00,270 --> 00:01:06,450
And then we're going to have one final chapter and which we're going to look at some more advanced Cortland

18
00:01:06,450 --> 00:01:07,830
basics, so to speak.

19
00:01:08,010 --> 00:01:11,760
And then we can finally get back to developing Android apps.

20
00:01:11,760 --> 00:01:15,840
So then we can finally use all of the knowledge and get started with it.

21
00:01:16,230 --> 00:01:16,650
OK.

22
00:01:16,770 --> 00:01:22,740
So just work yourself through it, and then we are going to build some cool apps, so see you in the

23
00:01:22,740 --> 00:01:23,370
next video.
