1
00:00:00,880 --> 00:00:07,550
The class keyword so you can replace the struct keyword within the class keyword.

2
00:00:07,570 --> 00:00:11,220
So which declares members private by default.

3
00:00:11,230 --> 00:00:13,700
So aside from default access controls.

4
00:00:13,720 --> 00:00:18,970
Classes declared with the struct and class keywords are the same.

5
00:00:18,970 --> 00:00:24,340
So for example, you could declare my date and time just the class here.

6
00:00:24,340 --> 00:00:29,290
As you can see here, we just need to arrange these methods here.

7
00:00:30,340 --> 00:00:41,500
So then here, as you can see here, let's make this like that and here and we will make this functions

8
00:00:41,500 --> 00:00:42,490
public.

9
00:00:42,880 --> 00:00:47,830
And as you can see here, we can run our code without any problem here.

10
00:00:47,830 --> 00:00:52,480
So which way you declare class is a matter of style.

11
00:00:52,480 --> 00:00:59,980
So there's absolutely no difference between between struct and class aside from the access controls.

12
00:00:59,980 --> 00:01:04,300
So there are they are almost same and they are.

13
00:01:05,940 --> 00:01:07,390
They are like, absolutely insane.

14
00:01:07,390 --> 00:01:14,650
But they have like different they are different thing differentiating on access controls.

15
00:01:14,650 --> 00:01:18,730
So I prefer using struct sometimes, sometimes class.

16
00:01:18,730 --> 00:01:26,200
So and you may like use struct because having the public members listed first.

17
00:01:26,200 --> 00:01:32,350
So but you will see all kinds of conventions out in the programming life.

18
00:01:32,470 --> 00:01:36,190
So cultivate a style and stick to it.

19
00:01:36,490 --> 00:01:38,260
So now I want to.

20
00:01:39,470 --> 00:01:43,040
Having encapsulated the we have encapsulated here.

21
00:01:43,040 --> 00:01:45,650
As you can see here, we have get.

22
00:01:45,680 --> 00:01:46,970
Here and add here.

23
00:01:46,970 --> 00:01:51,200
So you must now use methods to interact with this.

24
00:01:52,000 --> 00:01:53,470
The my date and time.

25
00:01:53,470 --> 00:01:56,110
So here I want to.

26
00:01:57,420 --> 00:02:00,660
Seth for something here, so.

27
00:02:01,750 --> 00:02:05,980
Let's delete this code and create new.

28
00:02:06,230 --> 00:02:12,250
Here my date and time and clock.

29
00:02:13,650 --> 00:02:14,220
Here.

30
00:02:14,220 --> 00:02:16,980
If here not.

31
00:02:16,980 --> 00:02:17,610
Operator.

32
00:02:17,610 --> 00:02:18,820
Ternary operator.

33
00:02:18,840 --> 00:02:21,420
Clock dot set here.

34
00:02:22,190 --> 00:02:23,690
2018.

35
00:02:25,380 --> 00:02:29,060
Here and clock that set here.

36
00:02:29,110 --> 00:02:30,330
Dozen 19.

37
00:02:31,560 --> 00:02:41,940
And then I will explain all of these codes here, clock that are here, here, and print f here.

38
00:02:42,450 --> 00:02:45,630
Here is the.

39
00:02:47,220 --> 00:02:50,220
And clock that get here.

40
00:02:52,000 --> 00:02:52,600
Let's run.

41
00:02:53,050 --> 00:02:53,890
Let's run our code.

42
00:02:53,890 --> 00:02:59,170
As you can see, we got the output of to 2020 here.

43
00:02:59,170 --> 00:03:07,150
So firstly, we declare the clock here and attempt to set its year to 2018.

44
00:03:07,270 --> 00:03:08,320
So.

45
00:03:09,320 --> 00:03:13,950
This file fails because 2018 is less than 2019.

46
00:03:13,970 --> 00:03:17,440
As you can see here, we will we will.

47
00:03:17,450 --> 00:03:26,480
As you remember in previous lectures, we will return false from if our set year value parameter had

48
00:03:26,990 --> 00:03:28,840
less than 2019.

49
00:03:28,850 --> 00:03:37,400
So in this case this statement the here returned true because we have the ternary operator here.

50
00:03:37,400 --> 00:03:42,530
So if you have this operator, we just change true to false.

51
00:03:42,560 --> 00:03:44,480
If it's false to true.

52
00:03:44,480 --> 00:03:55,220
So and then you increment here, as you can see here, you increment a clock that add a year by one

53
00:03:55,520 --> 00:03:57,980
with this function and.

54
00:03:59,100 --> 00:04:04,830
Now you increment it once and you get the get here and here.

55
00:04:05,250 --> 00:04:07,590
This output of it here.
