00:00:00,480 --> 00:00:01,350
‫Welcome back.

2
00:00:01,380 --> 00:00:06,600
‫In this video, we are going to cover switch and case statements which are similar to if statements.

3
00:00:06,600 --> 00:00:10,020
‫And let's go ahead and simply create a switch case.

4
00:00:10,020 --> 00:00:16,020
‫So I'm here in here in my program and I create a variable first, which is going to be my comparison

5
00:00:16,020 --> 00:00:16,440
‫variable.

6
00:00:16,440 --> 00:00:22,320
‫So I want to compare or to check this variable and see if it has a specific value.

7
00:00:22,320 --> 00:00:26,700
‫And in my switch case statement, I can check those.

8
00:00:26,700 --> 00:00:32,520
‫So switch is the actual switch like a switch which you can turn on and off.

9
00:00:32,520 --> 00:00:36,720
‫Or you could, for example, have multiple different values for the switch.

10
00:00:36,720 --> 00:00:40,470
‫It could switch to ten to 15 to 25, whatever.

11
00:00:40,470 --> 00:00:49,020
‫And in this case, I just want to compare the age now I need to curly brackets to create my switch body.

12
00:00:49,020 --> 00:00:51,060
‫And then here I can have my different cases.

13
00:00:51,060 --> 00:00:53,220
‫So let's say the case 15.

14
00:00:53,220 --> 00:00:57,720
‫What if somebody is 15 then I want to write to the console.

15
00:00:57,960 --> 00:01:02,280
‫Too young to party in the club.

16
00:01:02,970 --> 00:01:08,010
‫So if somebody is 15 he can't get into the club and then we need to break.

17
00:01:08,040 --> 00:01:12,630
‫Otherwise this case is going to create errors.

18
00:01:12,630 --> 00:01:17,400
‫So it says break, which means if we get into this code here.

19
00:01:17,400 --> 00:01:21,810
‫So the case 15 was true, we need to break out of the switch statement.

20
00:01:22,080 --> 00:01:26,970
‫So the next one would be case, let's say 25.

21
00:01:26,970 --> 00:01:33,570
‫And here you could use any case, you could use case ten, 20, 30, 15, 16, whatever.

22
00:01:33,840 --> 00:01:38,010
‫And here I also write something on to the console.

23
00:01:38,430 --> 00:01:40,080
‫Good to go.

24
00:01:40,080 --> 00:01:42,690
‫So if somebody is 25, he's good to go.

25
00:01:42,690 --> 00:01:44,850
‫And here I need to break out as well.

26
00:01:45,060 --> 00:01:52,650
‫So always this structure, we have the switch statement, then you compare the variable, then you have

27
00:01:52,650 --> 00:01:56,640
‫the curly brackets and within the curly brackets you have all the different cases.

28
00:01:56,640 --> 00:02:03,240
‫So you use the word case, then the value that you want to check colon, then the code that you want

29
00:02:03,240 --> 00:02:05,640
‫to execute and finally you use break.

30
00:02:05,640 --> 00:02:06,000
‫All right.

31
00:02:06,000 --> 00:02:08,580
‫So is simply the structure that you have here.

32
00:02:08,640 --> 00:02:14,820
‫And then there is one case that you can add, and that's the default case.

33
00:02:14,820 --> 00:02:20,310
‫So this one is called whenever none of the others is true.

34
00:02:20,310 --> 00:02:24,960
‫So it's similar to the statement in a false statements.

35
00:02:25,320 --> 00:02:32,850
‫And in here I'm going to say if somebody is neither 15 nor 25, how old are you then?

36
00:02:33,330 --> 00:02:37,980
‫So that's just going to be the text written on to the console.

37
00:02:38,040 --> 00:02:40,890
‫And also, don't forget to use the break.

38
00:02:41,340 --> 00:02:41,580
‫All right.

39
00:02:41,580 --> 00:02:44,250
‫So that's simply the switch in case statement.

40
00:02:44,250 --> 00:02:50,970
‫And in here, I'm going to add the console dot, right.

41
00:02:50,970 --> 00:02:54,420
‫So that we can see something on the console.

42
00:02:54,420 --> 00:02:57,570
‫So I'm going to start a code or start the program.

43
00:02:57,720 --> 00:03:02,940
‫And in a second we should see our program and it says Good to go.

44
00:03:02,940 --> 00:03:04,650
‫That's because we are 25.

45
00:03:04,650 --> 00:03:07,680
‫So what if we are 19?

46
00:03:08,040 --> 00:03:12,360
‫Let's run the code and it says, How old are you then?

47
00:03:13,320 --> 00:03:17,190
‫So you see, this is how you can simply use a switch case statement.

48
00:03:19,020 --> 00:03:20,710
‫Now is a little challenge for you.

49
00:03:20,760 --> 00:03:24,390
‫Try to reproduce that as an if statement.

50
00:03:26,930 --> 00:03:27,320
‫All right.

51
00:03:27,320 --> 00:03:28,550
‫I hope you tried it.

52
00:03:28,700 --> 00:03:40,490
‫So I'm just going to put it just underneath and I'm going to say if H is equal to 15, then go ahead

53
00:03:40,490 --> 00:03:48,560
‫and write console dot right line to young to party in the club.

54
00:03:50,930 --> 00:03:57,200
‫And then else if age is equal to 25.

55
00:03:58,310 --> 00:03:58,880
‫Right.

56
00:03:58,880 --> 00:03:59,990
‫Good to go.

57
00:04:01,610 --> 00:04:03,350
‫And finally, let's.

58
00:04:05,750 --> 00:04:08,060
‫How old are you then?

59
00:04:08,690 --> 00:04:13,580
‫So as you can see, this is how we do it with an f l statement and this is how we do a switch case.

60
00:04:14,030 --> 00:04:22,940
‫And you can always use if statements, but in some cases a switch case statement is more appealing and

61
00:04:22,940 --> 00:04:24,080
‫easier to handle.

62
00:04:24,080 --> 00:04:30,950
‫And well, you can of course still use f l statements if you don't like to use switch case statements.

63
00:04:30,950 --> 00:04:32,720
‫But don't be confused.

64
00:04:32,720 --> 00:04:39,170
‫If you ever see a switch case statement and code that you see in a tutorial or code that is used somewhere

65
00:04:39,170 --> 00:04:41,540
‫in StackOverflow or in the Internet.

66
00:04:41,570 --> 00:04:48,050
‫Now let's have a quick look at a switch statement when you use strings.

67
00:04:48,050 --> 00:04:54,650
‫So I'm going to use a click quick string and I'm going to call it one username and it's going to be

68
00:04:54,650 --> 00:04:55,400
‫Dennis.

69
00:04:55,520 --> 00:05:02,530
‫So now let's create a switch statement which simply checks, switch checks the username.

70
00:05:04,180 --> 00:05:11,180
‫And, and here I'm going to have a case of Dennis.

71
00:05:11,180 --> 00:05:17,840
‫So if Dennis is the case, then go ahead and write something onto the console.

72
00:05:17,840 --> 00:05:25,610
‫So console dot right line user name is Dennis.

73
00:05:28,740 --> 00:05:30,510
‫And of course, we need the break.

74
00:05:32,730 --> 00:05:39,040
‫Now, the next case could be somebody has the username of route, case, route.

75
00:05:41,010 --> 00:05:46,860
‫Then we simply write root user or user name is root.

76
00:05:47,790 --> 00:05:51,870
‫And finally, we need to default case.

77
00:05:52,410 --> 00:05:58,950
‫So if neither of those two cases is true, then just go ahead and write something like.

78
00:06:01,070 --> 00:06:03,890
‫Username is unknown.

79
00:06:06,190 --> 00:06:06,730
‫All right.

80
00:06:06,730 --> 00:06:12,990
‫So I'm just going to change that from Dennis to Frank, just to see what to show you, what happens.

81
00:06:13,000 --> 00:06:16,690
‫So let's run the code and we see how old are you then?

82
00:06:16,690 --> 00:06:17,650
‫It's written twice.

83
00:06:17,650 --> 00:06:23,980
‫That's our two if statements or the switch case and the if statement and then we have the second one.

84
00:06:23,980 --> 00:06:28,510
‫Username is unknown, so you can't only use it with integers.

85
00:06:28,510 --> 00:06:32,980
‫You can also use it with strings and with other data types as well.
