00:00:03,630 --> 00:00:07,420
In this practice lecture, your task would be to create two functions.

2
00:00:07,860 --> 00:00:14,520
The first one should take a CHA, the energy efficiency category and print out the energy consumption

3
00:00:14,790 --> 00:00:24,450
of each level by using a switch or if as a standard for very low, B is low, C normal.

4
00:00:24,750 --> 00:00:33,450
The above normal is high, F is very high, and G is extremely high energy consumption.

5
00:00:34,020 --> 00:00:41,580
I would suggest you to make the function compatible with lowercase and uppercase char arguments.

6
00:00:41,970 --> 00:00:49,740
Also, I would like you to modify the function to return a string and print out the return string with

7
00:00:49,740 --> 00:00:57,290
a system that Outbrain on the second function should print out a car description and it should have

8
00:00:57,300 --> 00:01:04,800
three parameters string car model and production year and string condition.

9
00:01:05,100 --> 00:01:07,900
It can be good, bad, used or damaged.

10
00:01:08,430 --> 00:01:15,390
I also suggest you to post the video here and try to do this on your own and get back here after you've

11
00:01:15,390 --> 00:01:18,390
finished and compare your code to mine.

12
00:01:18,570 --> 00:01:24,720
If something is not clear for you or you think you have another solution, feel free to share that with

13
00:01:24,720 --> 00:01:26,230
me, OK?

14
00:01:26,400 --> 00:01:28,820
You can create a new class for this task.

15
00:01:29,100 --> 00:01:35,550
I'm going to add the two functions to the functions and class we created in the last lecture.

16
00:01:36,240 --> 00:01:36,720
All right.

17
00:01:36,720 --> 00:01:42,030
Start with static void.

18
00:01:43,800 --> 00:01:59,700
The function name gets energy of efficiency, Prentice's char category, curly braces, and I'm going

19
00:01:59,700 --> 00:02:11,730
to use switchgear service, which it's going to take to category curly braces, case single quotes,

20
00:02:12,180 --> 00:02:13,440
uppercase A..

21
00:02:14,580 --> 00:02:20,890
And Callon, as I said, it, should able to take lowercase letters as well.

22
00:02:20,910 --> 00:02:22,920
So case.

23
00:02:24,400 --> 00:02:42,430
Simple coats, a hand column now stand out out of print on darbo coats, very low energy consumption

24
00:02:45,940 --> 00:02:58,420
and break and a semicolon now copied these lines, copy paste it here and again.

25
00:02:58,630 --> 00:03:00,460
And again and again.

26
00:03:02,020 --> 00:03:08,620
Change A to B, then C,

27
00:03:12,040 --> 00:03:12,550
D,

28
00:03:15,910 --> 00:03:16,270
e.

29
00:03:23,140 --> 00:03:23,930
Beth.

30
00:03:28,370 --> 00:03:31,160
And lost G.

31
00:03:37,420 --> 00:03:44,170
Change the text, so it's going to be low, C is normal.

32
00:03:49,670 --> 00:03:51,320
These is normal.

33
00:03:58,100 --> 00:03:59,270
He is high.

34
00:04:05,810 --> 00:04:07,620
I have a very high.

35
00:04:11,720 --> 00:04:13,820
And she is extremely high.

36
00:04:21,700 --> 00:04:24,440
What is missing here is a default.

37
00:04:25,340 --> 00:04:38,850
So default and system out of print alone, not defined category.

38
00:04:43,650 --> 00:04:46,890
Now call the function in the main method, so.

39
00:04:50,880 --> 00:04:55,470
Get energy efficiency and use a as an argument.

40
00:04:58,320 --> 00:04:59,460
Now we're in a code.

41
00:05:02,170 --> 00:05:14,050
And the proper taxes printed out now try with a lowercase G once again, and that's correct again now

42
00:05:14,050 --> 00:05:19,020
change the function from Boyte to return a string and print out that string.

43
00:05:19,480 --> 00:05:22,300
So scroll back here.

44
00:05:22,870 --> 00:05:25,180
Change Voit to string.

45
00:05:26,980 --> 00:05:37,450
And instead of system that I would to land use return and remove these parentheses, and we don't need

46
00:05:37,450 --> 00:05:44,750
a break anymore because of return and the execution and the code after that won't be wrong.

47
00:05:45,190 --> 00:05:46,900
So let's change that.

48
00:05:48,580 --> 00:05:52,630
And the other crisis to so return.

49
00:05:53,680 --> 00:05:54,670
Well, this.

50
00:05:55,970 --> 00:05:57,660
The little break as well.

51
00:06:00,200 --> 00:06:01,100
Return.

52
00:06:09,600 --> 00:06:13,800
So now the latest to break.

53
00:06:22,670 --> 00:06:24,140
Just a few times.

54
00:06:36,690 --> 00:06:38,070
And here to.

55
00:06:47,040 --> 00:06:54,540
OK, now scroll back, and instead of calling the function printout the return values, so this is standard

56
00:06:54,540 --> 00:06:55,680
output, Frinton.

57
00:07:01,170 --> 00:07:07,440
But let's change the argument to be now wrung out cold.

58
00:07:09,110 --> 00:07:11,900
All right, so low energy consumption is printed out.

59
00:07:12,700 --> 00:07:18,980
The good thing about modifying the function to return a string or any other value is that we can use

60
00:07:18,980 --> 00:07:22,210
that to return that value for other purposes.

61
00:07:23,340 --> 00:07:29,640
Now move on to our second function so that function should print out a short description of a car.

62
00:07:30,990 --> 00:07:33,720
Starting with static.

63
00:07:35,740 --> 00:07:56,590
Void Girths, car description Prentice's string model Colma and production year Colma string condition

64
00:07:59,140 --> 00:08:04,370
curly braces system that outthought print on Tombo codes.

65
00:08:05,020 --> 00:08:05,980
This.

66
00:08:07,420 --> 00:08:09,850
This car is a.

67
00:08:12,760 --> 00:08:14,470
Plus model.

68
00:08:17,990 --> 00:08:20,630
Double this line changed a text.

69
00:08:24,380 --> 00:08:42,320
Production here, Colin, used to worry about production year, double this line it is and change the

70
00:08:42,320 --> 00:08:50,720
variable name to conversion, plus the quotes space cannulation.

71
00:08:53,900 --> 00:08:57,140
Lay this out, there is a typo.

72
00:08:59,100 --> 00:09:02,040
Now, call this matter at the end of the main method.

73
00:09:04,240 --> 00:09:05,080
So.

74
00:09:06,400 --> 00:09:16,600
Get a car description, the first parameters model, I will use Tesla Roadster,

75
00:09:19,900 --> 00:09:29,890
comma, production year 2018, coma conditions and in good condition.

76
00:09:31,580 --> 00:09:32,930
Now, on called again.

77
00:09:35,520 --> 00:09:41,640
It seems everything works properly at the end, I suggest you to create your own version.

78
00:09:42,000 --> 00:09:45,270
I hope this lecture was helpful seeing the next one.
