1
00:00:00,820 --> 00:00:05,620
Now we can add the second action, searching a car, we're almost done building that dealership up so

2
00:00:05,620 --> 00:00:09,120
far we've added everything from the requirements except for the search action.

3
00:00:09,880 --> 00:00:12,910
The customer is going to tell you what kind of car they want and their budget.

4
00:00:13,270 --> 00:00:18,580
And so the search action needs to search through all the cars in the dealership and find one that suits

5
00:00:18,580 --> 00:00:19,210
the customer.

6
00:00:22,220 --> 00:00:25,370
All right, so in this lesson, we're going to add the search car action.

7
00:00:28,310 --> 00:00:30,890
We need to add a search action to the dealership class.

8
00:00:33,360 --> 00:00:37,830
So inside at a method called search, the method is going to return a string that tells the customer

9
00:00:37,830 --> 00:00:38,970
what the dealership found.

10
00:00:41,150 --> 00:00:43,790
And it needs to parameters make and a budget.

11
00:00:49,430 --> 00:00:52,520
And for now, return, sorry, we couldn't find any cars.

12
00:01:08,880 --> 00:01:10,630
Now a customer is looking for a dodge.

13
00:01:10,650 --> 00:01:14,520
Their budget is a thousand, so have the dealership perform a search for a dodge.

14
00:01:15,800 --> 00:01:17,150
Dealership, not search.

15
00:01:26,600 --> 00:01:29,540
All right, we'll print the result of the search, the return value.

16
00:01:36,150 --> 00:01:41,130
And I want to run the code and make sure everything works as it's supposed to just for testing purposes.

17
00:01:51,490 --> 00:01:54,700
All right, for now, it returns a fixed message as expected.

18
00:01:57,800 --> 00:01:59,930
And we need to add some logic into the action.

19
00:02:01,730 --> 00:02:06,860
So we're going to make a for loop that runs through every car in the dealership, we can use the autocomplete

20
00:02:06,860 --> 00:02:10,639
feature and it's going to create a fault that runs through the nearest the right, in this case, our

21
00:02:10,639 --> 00:02:11,120
field.

22
00:02:13,920 --> 00:02:18,330
And even though we don't need to in this case, I like to always did this keyword when referring to

23
00:02:18,330 --> 00:02:21,630
a field anyways for each car object, the loop runs through.

24
00:02:21,640 --> 00:02:27,960
We need to check if the make matches the one you passed in, and we need to check if the price is equal

25
00:02:27,960 --> 00:02:30,240
to or lower than the customer's budget.

26
00:02:31,990 --> 00:02:34,150
I hope this makes you think of the and operator.

27
00:02:35,620 --> 00:02:37,660
So if they stock cars.

28
00:02:42,420 --> 00:02:46,200
We'll get the make and we'll check if it's equal to the make being passed in.

29
00:02:53,400 --> 00:02:56,190
And if that same car's price.

30
00:03:05,850 --> 00:03:08,310
Is less than or equal to the person's budget.

31
00:03:14,400 --> 00:03:17,130
If that condition is true, that means we found a car for them.

32
00:03:20,240 --> 00:03:22,100
Before we had any more code, let's run it.

33
00:03:36,360 --> 00:03:43,710
Henare Code Crash's, this is great news because we get to fix our code, it says null pointer, which

34
00:03:43,710 --> 00:03:46,650
means we're trying to access or cull something from a note.

35
00:03:47,130 --> 00:03:49,920
If you read the error, it tells you exactly where this happens.

36
00:03:50,190 --> 00:03:50,910
In Maine.

37
00:03:51,150 --> 00:03:55,110
I called dealership search at line 19 of Maine.

38
00:03:57,180 --> 00:04:00,930
This runs code in the dealership class crashing at line 25.

39
00:04:04,350 --> 00:04:07,560
Now, your line numbers might be different, but here is the line that crashed.

40
00:04:09,810 --> 00:04:15,570
When I is zero or one, we can safely index the first and second objects and extract values from them.

41
00:04:22,650 --> 00:04:28,070
But when I used to we're indexing the third element, which is no, and if you try to access or call

42
00:04:28,090 --> 00:04:30,660
something from a null, the code is going to crash.

43
00:04:31,320 --> 00:04:33,540
This is what we call a null pointer exception.

44
00:04:33,900 --> 00:04:39,900
If you try accessing or dot syntax, something from a null Java is going to crash and throw an exception.

45
00:04:40,900 --> 00:04:45,620
Now, one of the objectives no, and you can't dot syntax anything from another object.

46
00:04:45,970 --> 00:04:48,340
So what we'll do is if the object is no.

47
00:05:00,830 --> 00:05:03,770
We can use continue to skip that run in the loop.

48
00:05:20,950 --> 00:05:25,750
All right, so as the loop runs, if the object is not the first condition is going to execute and skip

49
00:05:25,750 --> 00:05:29,830
that run in the loop in this case, it's going to skip the run when the index is to.

50
00:05:34,810 --> 00:05:39,040
All right, let's finish our code, if we find the car that matches what the customer wants, then this

51
00:05:39,040 --> 00:05:40,270
condition executes.

52
00:05:40,270 --> 00:05:42,640
In this case, we're going to return a message to the user.

53
00:05:45,180 --> 00:05:46,470
Will return new line.

54
00:05:46,650 --> 00:05:48,210
We found one in spot.

55
00:05:53,580 --> 00:05:56,910
I whatever the index is, when this condition turns true.

56
00:06:07,640 --> 00:06:10,070
And then we'll print the two string of the car object.

57
00:06:19,200 --> 00:06:19,920
Newline.

58
00:06:22,620 --> 00:06:23,550
Are you interested?

59
00:06:37,410 --> 00:06:39,510
I still can't find any cars for our customer.

60
00:06:39,630 --> 00:06:44,190
The customer is looking for a dodge with a budget of eight thousand, but we're only selling one dodge

61
00:06:44,190 --> 00:06:46,140
and it's worth eight thousand five hundred.

62
00:06:49,260 --> 00:06:52,470
So the customer decides to change their budget to 10000.

63
00:07:00,350 --> 00:07:04,490
And it finds the McCarren spot one nice found the MCCA.

64
00:07:07,540 --> 00:07:09,940
First, the condition is false and nothing happens.

65
00:07:18,950 --> 00:07:23,870
But once the loop gets to inducts one, the condition is true and it returns a string that tells the

66
00:07:23,870 --> 00:07:25,190
customer what we found.

67
00:07:33,070 --> 00:07:38,440
This is great, you built a dealership application that manages cells and searches for cars and you

68
00:07:38,440 --> 00:07:40,960
program the entire thing using objects.

69
00:07:45,030 --> 00:07:50,610
In this lesson, you had a desert correction, you built an entire project by planting it around objects,

70
00:07:50,610 --> 00:07:52,140
fields and actions.
