1
00:00:00,520 --> 00:00:03,910
In this lesson, you will add getters to the car class.

2
00:00:05,840 --> 00:00:09,290
You might be wondering, everything is working nice and perfect.

3
00:00:09,290 --> 00:00:11,360
Why are we adding getters?

4
00:00:11,600 --> 00:00:18,800
The issue with the syntax is let's just say my intention is to just access the objects as make field.

5
00:00:18,830 --> 00:00:25,820
Well, using this same syntax, I could accidentally update this field to be Toyota when in fact it

6
00:00:25,820 --> 00:00:28,010
should have a string called Nissan.

7
00:00:28,010 --> 00:00:35,750
So having direct access to an object field is not very safe and it's considered very, very bad practice,

8
00:00:35,750 --> 00:00:41,120
which is why we have to make every single field private to the car class.

9
00:00:47,880 --> 00:00:52,840
So private means that the field is private to the class that it was defined in.

10
00:00:52,860 --> 00:00:55,180
It is not visible anywhere else.

11
00:00:55,200 --> 00:01:02,100
So if we go back to Main Java here, we're trying to directly access the make field, but the make field

12
00:01:02,100 --> 00:01:03,420
is not visible.

13
00:01:05,090 --> 00:01:08,850
Each field is private to the class that it was defined in.

14
00:01:08,870 --> 00:01:11,300
It is not visible anywhere else.

15
00:01:12,610 --> 00:01:15,880
The thing is, I still need to print the Nissan object's fields.

16
00:01:15,880 --> 00:01:19,180
So how can I get all of its field values?

17
00:01:20,020 --> 00:01:24,940
So while the fields are private, a getter is a public method.

18
00:01:25,990 --> 00:01:33,010
Whose return type depends on a particular field and it's always going to be called get followed by the

19
00:01:33,010 --> 00:01:36,520
name of your field again, using camel case.

20
00:01:38,640 --> 00:01:44,550
And what it will do is return the field of the current object that calls this method.

21
00:01:46,100 --> 00:01:48,020
Now we'll create another gutter.

22
00:01:48,050 --> 00:01:50,210
This one needs to return a double.

23
00:01:50,480 --> 00:01:52,670
It will be called Get price.

24
00:01:55,200 --> 00:02:00,540
And it will return the price field of the current object that calls this method.

25
00:02:01,880 --> 00:02:08,990
Now notice we don't need to say this make or this the price because there is no conflicting parameter.

26
00:02:10,130 --> 00:02:16,080
Java is smart enough to return the make field of the current object calls this method.

27
00:02:16,100 --> 00:02:18,230
Now we're going to need another getter.

28
00:02:18,620 --> 00:02:20,780
This one will return an integer.

29
00:02:21,540 --> 00:02:23,070
It's going to be called get.

30
00:02:23,070 --> 00:02:23,790
Yea.

31
00:02:24,720 --> 00:02:27,000
And it needs to return the year.

32
00:02:27,810 --> 00:02:30,420
Of whatever object calls this method.

33
00:02:31,810 --> 00:02:36,250
The final gutter we need to declare is one that returns a string.

34
00:02:37,500 --> 00:02:39,450
It will be called Get Color.

35
00:02:40,130 --> 00:02:46,910
And it needs to return the color field of whatever object is currently calling this method.

36
00:02:48,790 --> 00:02:50,440
So now what we have is perfect.

37
00:02:50,440 --> 00:02:56,620
Our fields are safe, sound and private, and each field has a public getter that returns a copy of

38
00:02:56,620 --> 00:02:57,400
its value.

39
00:02:57,880 --> 00:02:59,320
So now we're good to go.

40
00:03:00,340 --> 00:03:04,350
Here because we no longer have direct access to an object as field.

41
00:03:04,360 --> 00:03:06,640
What we can do is call it's getter.

42
00:03:06,640 --> 00:03:10,960
So Nissan get make Nissan get price.

43
00:03:11,980 --> 00:03:16,510
Nissan jet year and Nissan jet color.

44
00:03:16,780 --> 00:03:19,720
We can do the same thing here from the Dodge object.

45
00:03:19,720 --> 00:03:22,570
We can call get make here.

46
00:03:22,570 --> 00:03:25,960
We can call get price get year.

47
00:03:26,690 --> 00:03:28,310
And get color.

48
00:03:29,730 --> 00:03:38,070
Okay, I'm going to add breakpoints inside every getter because it's going to be really hard pressing

49
00:03:38,070 --> 00:03:42,150
the step in to button when we're already inside the print line function.

50
00:03:42,150 --> 00:03:44,400
So we'll put breakpoints here.

51
00:03:49,040 --> 00:03:52,840
So at this point, we've created two new objects of the car class.

52
00:03:52,850 --> 00:03:55,820
Each variable stores a reference to that object.

53
00:03:56,000 --> 00:03:59,120
First we call get make for this object.

54
00:04:04,200 --> 00:04:07,950
This refers to the current object that's calling this method.

55
00:04:07,950 --> 00:04:11,280
And here we return the make field of that object.

56
00:04:15,770 --> 00:04:19,430
The second getter that gets called was get price.

57
00:04:20,800 --> 00:04:24,040
Which is going to return the price field of the current object.

58
00:04:24,670 --> 00:04:30,490
The third getter that gets called is get Yea, which is going to return the year field of the current

59
00:04:30,490 --> 00:04:31,360
object.

60
00:04:35,570 --> 00:04:41,750
And the fourth getter that gets called is get Cutler, which is going to return the color field of the

61
00:04:41,750 --> 00:04:43,070
current object.

62
00:04:43,100 --> 00:04:49,160
If I press next, it prints every single field inside of the Nissan object.

63
00:04:50,250 --> 00:04:55,980
And now once again, we call get make, get price, get yea get color, but we're going to call these

64
00:04:55,980 --> 00:04:57,900
gutters for this object.

65
00:04:58,290 --> 00:04:59,430
And so once again.

66
00:05:00,560 --> 00:05:04,770
This points to the current object that's calling this method.

67
00:05:04,790 --> 00:05:07,230
That object is make is dodge.

68
00:05:07,250 --> 00:05:08,870
That's what's going to get returned.

69
00:05:08,900 --> 00:05:12,170
Here we return the price of the current object.

70
00:05:12,740 --> 00:05:15,800
Here we return the year of the current object.

71
00:05:16,340 --> 00:05:18,410
And here we return the color.

72
00:05:20,990 --> 00:05:21,790
And that's it.

73
00:05:25,170 --> 00:05:30,450
So to recap, you should always use gutters to access your objects as fields.
