1
00:00:00,060 --> 00:00:00,240
OK.

2
00:00:00,320 --> 00:00:06,340
And welcome back to another class, of course, about the complete introduction to the debate with except

3
00:00:06,810 --> 00:00:13,320
so in this class, we are going to talk a little bit about what exactly is an object oriented language.

4
00:00:13,800 --> 00:00:19,440
So this way, you guys will understand a little bit more what exactly this is and what's the difference

5
00:00:19,440 --> 00:00:22,350
between object oriented language and other languages.

6
00:00:22,380 --> 00:00:26,960
And also talk about a few examples of object oriented languages.

7
00:00:27,180 --> 00:00:28,600
So let's start.

8
00:00:29,880 --> 00:00:30,150
All right.

9
00:00:30,170 --> 00:00:33,660
So what exactly is an object oriented language?

10
00:00:33,930 --> 00:00:43,230
So we can call we can say that that it's a computer programming model like here that will organize software

11
00:00:43,350 --> 00:00:45,000
designs around that.

12
00:00:45,300 --> 00:00:53,070
Or also we can say that it's designed around the project rather than, let's say, functions.

13
00:00:54,300 --> 00:01:02,580
Also, an object can be defined as, for example, Darfield that has that unique or have unique behaviors

14
00:01:04,290 --> 00:01:04,800
also.

15
00:01:05,160 --> 00:01:07,220
Well, in other words, what does this means?

16
00:01:07,290 --> 00:01:15,780
It means that will it will focus on a certain object and it can be really beneficial for well, for

17
00:01:15,780 --> 00:01:18,280
club, for collaborative development.

18
00:01:18,600 --> 00:01:22,500
So in other words, let's say, for example, I'm working on a certain project.

19
00:01:23,370 --> 00:01:29,430
It's possible for me, for example, to leave the project and someone else can take the lead and simply

20
00:01:29,430 --> 00:01:30,840
work on the project as well.

21
00:01:30,870 --> 00:01:38,460
So basically, we can work in teams on this project and basically just separate the tasks, which is

22
00:01:38,460 --> 00:01:44,790
pretty cool with a well, with a object oriented programming language.

23
00:01:45,220 --> 00:01:52,290
Also, it will focus on the object that that, for example, you want to manipulate rather than, as

24
00:01:52,290 --> 00:01:56,410
I said, the function or the logic that is required to manipulate it.

25
00:01:56,430 --> 00:02:04,050
So basically, you were only focusing on a certain object and it's well suited for programs that are

26
00:02:04,260 --> 00:02:06,410
well, that are pretty large.

27
00:02:06,420 --> 00:02:11,790
So let's say, for example, you want to program a large application or something really big, you are

28
00:02:11,790 --> 00:02:17,800
going to use an object programming language, such as, for example, Python or in our case, VBA.

29
00:02:19,140 --> 00:02:25,710
So in this case, well, if we want to talk about a few principles of an object programming language,

30
00:02:26,250 --> 00:02:27,970
in my opinion, there are four of them.

31
00:02:28,620 --> 00:02:30,540
The first one will be encapsulation.

32
00:02:30,550 --> 00:02:37,860
So basically that it's the implementation and the state of each object that are privately held inside

33
00:02:37,860 --> 00:02:40,890
of a defined boundary or a class.

34
00:02:42,120 --> 00:02:47,250
Then we'll talk about the well, then there is the principle of abstraction.

35
00:02:48,120 --> 00:02:55,230
So this means that it will only review internal mechanism that are relevant for the use of other objects

36
00:02:55,260 --> 00:02:57,080
and only if it's necessary.

37
00:02:57,090 --> 00:03:04,500
So very important to understand and then will have inheritance, which is the relationship and well,

38
00:03:04,530 --> 00:03:10,860
relationship and subclasses that are between objects that we have assigned and finally polymorphism,

39
00:03:10,860 --> 00:03:19,080
which simply means that the object can take on more than one form depending of the context.

40
00:03:19,380 --> 00:03:20,880
So basically we can have more than one form.

41
00:03:21,810 --> 00:03:27,540
So basically what I'm trying to say, what I'm trying to present you here is what exactly is a well,

42
00:03:27,540 --> 00:03:32,190
in this case, what exactly is a object oriented language?

43
00:03:32,370 --> 00:03:35,120
And once again, this is just a pure theory.

44
00:03:35,610 --> 00:03:40,470
But this way you guys will have a basic understanding of what exactly this is.

45
00:03:40,500 --> 00:03:46,800
So if we want to talk about a few examples of what exactly is a an object oriented language, we can,

46
00:03:46,800 --> 00:03:52,090
for example, think of Python, which is one of the most popular or C++, for example.

47
00:03:52,770 --> 00:03:58,890
So basically those languages are, well, we can say advanced programming languages and that that they

48
00:03:58,890 --> 00:04:05,550
there are really used in the modern world to create different applications and different programs or

49
00:04:05,550 --> 00:04:06,600
even websites.

50
00:04:07,350 --> 00:04:08,700
VBA is one of them.

51
00:04:08,700 --> 00:04:12,180
So we can say that VBA is an object oriented programming language.

52
00:04:12,900 --> 00:04:18,210
It's a little bit different, but once again, it's an advanced programming language as well.

53
00:04:18,390 --> 00:04:24,530
And it's really used in when we are using Excel, for example, and also in Microsoft suites.

54
00:04:24,540 --> 00:04:29,250
Well, basically, when we're talking about object oriented languages, well, it's really, really

55
00:04:29,250 --> 00:04:30,990
used in the Microsoft Suite.

56
00:04:31,980 --> 00:04:36,820
And VBA is one example of those programming languages.

57
00:04:37,200 --> 00:04:42,420
So right now you have a basic introduction of what exactly is a object oriented language.

58
00:04:42,840 --> 00:04:44,760
And once again, this is just theory.

59
00:04:45,000 --> 00:04:50,010
And yeah, so basically this is what exactly is VBA.

60
00:04:50,280 --> 00:04:53,550
So that's a first class goes into our next class.
