1
00:00:01,470 --> 00:00:08,940
The switch statements transfers control to one of several statements depending on the value of a condition,

2
00:00:08,940 --> 00:00:13,920
so which evaluates to either an integer or enumeration type.

3
00:00:14,820 --> 00:00:18,300
The switch keyboard denotes a switch statement.

4
00:00:18,420 --> 00:00:22,260
So the switch statements provide conditional branching.

5
00:00:22,470 --> 00:00:30,030
When a switch statement executes control, transfers to the case, fitting to the condition or to a

6
00:00:30,330 --> 00:00:34,460
default condition if no case matches the condition expression.

7
00:00:34,470 --> 00:00:42,480
So the case keyboard denotes a case where the default keyboard denotes the default condition.

8
00:00:42,960 --> 00:00:51,900
Somewhat confusing claim execution will continue until the end of the switch statement or to the break

9
00:00:52,140 --> 00:00:52,830
keyboard.

10
00:00:52,830 --> 00:01:00,810
So you will almost you will always find a break at each end of each description and condition.

11
00:01:00,810 --> 00:01:02,640
So let's create an example.

12
00:01:02,820 --> 00:01:03,810
Switch statement.

13
00:01:03,810 --> 00:01:05,760
For example switch.

14
00:01:06,610 --> 00:01:07,150
Here.

15
00:01:07,180 --> 00:01:08,620
This is our condition.

16
00:01:08,620 --> 00:01:18,100
And then we have a case, this case expression here, or you can write case like that in this and then

17
00:01:19,030 --> 00:01:26,270
handle a case here, and then you will add the here.

18
00:01:28,410 --> 00:01:31,550
And then you will add the brake here.

19
00:01:31,560 --> 00:01:36,120
After this quarter braces, you will add brake, which I will explain why.

20
00:01:36,870 --> 00:01:38,580
What what are these here?

21
00:01:39,060 --> 00:01:45,180
So then, for example, let's add second case case expression to.

22
00:01:46,630 --> 00:01:47,290
Here.

23
00:01:48,100 --> 00:01:51,940
And then let's add here.

24
00:01:52,960 --> 00:01:56,730
Handle, handle a case to here.

25
00:01:56,740 --> 00:02:04,630
And then, as always, we do in switch statements, we do break here.

26
00:02:04,990 --> 00:02:11,790
And after that, after that we have a default keyword in switch statement.

27
00:02:11,800 --> 00:02:19,600
So let's write this as well, default keyword, which I will explain what is default handle?

28
00:02:19,600 --> 00:02:24,340
The default keyword is default case here.

29
00:02:25,260 --> 00:02:36,450
So now I will begin to explain these what these keyboards are and how these such statement, such statement

30
00:02:36,450 --> 00:02:37,500
structure works.

31
00:02:37,620 --> 00:02:41,250
So let's start with this switch keyboard.

32
00:02:41,280 --> 00:02:48,720
So switch keyboard, followed by the condition in parentheses here.

33
00:02:49,720 --> 00:02:52,060
Actually, we don't need to parenthesis here.

34
00:02:52,960 --> 00:02:53,950
It's useless.

35
00:02:54,760 --> 00:03:00,370
So such statement followed by this condition parenthesis here.

36
00:03:01,610 --> 00:03:03,650
So all which begins with this.

37
00:03:03,860 --> 00:03:04,430
You can't.

38
00:03:04,850 --> 00:03:06,780
You just can't write.

39
00:03:06,890 --> 00:03:08,360
Write a case and then switch.

40
00:03:08,360 --> 00:03:10,220
So you have to do switch.

41
00:03:10,220 --> 00:03:13,250
And then cases and after that default here.

42
00:03:13,430 --> 00:03:24,620
So every switch statement starts with switch and condition here, and then each case begins with the

43
00:03:24,620 --> 00:03:33,350
case keyword here, followed by the cases enumeration or integral value.

44
00:03:34,610 --> 00:03:38,660
If condition equals here key.

45
00:03:38,840 --> 00:03:46,790
For example, case one, for example, the code in the block containing here handle case here will execute

46
00:03:47,990 --> 00:03:54,770
after each statement following a case here, you place a Greek keyword.

47
00:03:54,830 --> 00:03:59,120
So if condition matches none of the case.

48
00:03:59,570 --> 00:04:04,730
The default case here, as you can see here, is executes.

49
00:04:06,890 --> 00:04:09,320
So I want to add something here.

50
00:04:09,350 --> 00:04:17,570
The braces here enclosing each case are optional, but I highly recommend this.

51
00:04:17,600 --> 00:04:21,050
Without them, you will sometimes get surprising behavior.

52
00:04:21,050 --> 00:04:28,890
So always add these color braces about in the technical size technical view.

53
00:04:29,180 --> 00:04:33,560
It's not mandatory, but highly recommended.

54
00:04:34,360 --> 00:04:39,790
So let's create a switch statement with the enumeration class.

55
00:04:40,270 --> 00:04:41,610
So I'm going to delete this.

56
00:04:41,620 --> 00:04:43,450
You need this here.

57
00:04:44,500 --> 00:04:45,340
And here.

58
00:04:46,120 --> 00:04:47,080
So let's create an.

59
00:04:47,620 --> 00:04:51,280
First, let's create an enum class here, for example.

60
00:04:51,370 --> 00:04:52,900
Enum class.

61
00:04:54,300 --> 00:04:56,340
Here race.

62
00:04:57,440 --> 00:04:59,240
Or car models.

63
00:05:00,860 --> 00:05:04,550
For my car models here.

64
00:05:05,180 --> 00:05:07,790
I will explain all of these quotes here.

65
00:05:07,790 --> 00:05:13,160
For example, BMW, BMW, Mercedes.

66
00:05:15,060 --> 00:05:15,930
Renowned.

67
00:05:17,440 --> 00:05:18,250
Ferrari.

68
00:05:20,780 --> 00:05:21,800
Well, slugging.

69
00:05:22,780 --> 00:05:28,120
Bought your jeep, and I think that's enough.

70
00:05:30,210 --> 00:05:33,420
So as you can see, one, two, three, four, five, six, seven.

71
00:05:33,420 --> 00:05:35,550
We have seven car models here.

72
00:05:35,970 --> 00:05:41,730
So in main statement, let's write our switch switch case statements here.

73
00:05:42,090 --> 00:05:46,230
So let's click the object race here.

74
00:05:47,010 --> 00:05:49,330
Or my car models.

75
00:05:49,330 --> 00:05:50,560
My car models.

76
00:05:51,860 --> 00:05:57,340
Okay, so cars here or my cars.

77
00:05:58,180 --> 00:06:00,470
Equals mike are models.

78
00:06:00,550 --> 00:06:07,480
Here is operator and for example, Ferrari.

79
00:06:10,460 --> 00:06:15,470
So then I will explain all of these quotes as I do always.

80
00:06:15,680 --> 00:06:17,900
Switch here.

81
00:06:17,930 --> 00:06:18,770
Switch.

82
00:06:20,230 --> 00:06:27,260
As you can see here, our internal integrated environment automatically created this braces here.

83
00:06:27,280 --> 00:06:38,290
So now we will give the switch here, my cars, because we will use this in class here and we will use

84
00:06:38,290 --> 00:06:39,220
enum class members.

85
00:06:39,220 --> 00:06:48,550
So mainly firstly, we will give my car as a parameter and then we will write our case and default statements.

86
00:06:49,650 --> 00:06:51,120
So let's start with.

87
00:06:53,440 --> 00:06:56,470
Let's let's follow this order here.

88
00:06:56,740 --> 00:07:04,630
So switch case, switch, case, switch, case here.

89
00:07:05,380 --> 00:07:10,450
For my cars, my car models, for example, BMW.

90
00:07:10,600 --> 00:07:11,470
And then.

91
00:07:12,700 --> 00:07:14,200
Hair color braces.

92
00:07:14,350 --> 00:07:21,790
If the case is pretty BMW, you have a BMW.

93
00:07:22,150 --> 00:07:31,750
And then we will break code break this case statement after the caller braces here.

94
00:07:32,110 --> 00:07:34,660
And let's add another case here.

95
00:07:35,200 --> 00:07:49,790
Case, my car models, we have the messages here and then print if you have a mercedes Mercedes-Benz

96
00:07:49,810 --> 00:07:54,190
here, and then break our code.

97
00:07:54,730 --> 00:08:00,760
Break our code, add another case because we have six variables here.

98
00:08:01,030 --> 00:08:02,730
Then we have a result.

99
00:08:02,740 --> 00:08:13,660
My car models result here, print f you have a result here, and then break this as well.

100
00:08:14,950 --> 00:08:16,600
Uh, well, okay.

101
00:08:17,110 --> 00:08:17,600
Yeah.

102
00:08:18,580 --> 00:08:19,870
What's the problem here?

103
00:08:19,900 --> 00:08:22,000
Yeah, I fix that.

104
00:08:23,050 --> 00:08:27,070
And my car models renowned.

105
00:08:27,070 --> 00:08:30,190
We have a well here, we have Renault's.

106
00:08:30,190 --> 00:08:31,990
And let's add Volkswagen.

107
00:08:33,170 --> 00:08:35,480
A printer if you.

108
00:08:36,380 --> 00:08:42,920
You have a Volkswagen and then break this code also here.

109
00:08:42,920 --> 00:08:51,260
And lastly, we have two car models as my car models here.

110
00:08:52,160 --> 00:08:54,650
Let's add Ford and.

111
00:08:55,400 --> 00:08:56,000
Here.

112
00:08:58,070 --> 00:09:00,380
You have a fourth.

113
00:09:03,240 --> 00:09:04,200
Break.

114
00:09:05,100 --> 00:09:09,120
And lastly, my car was.

115
00:09:10,280 --> 00:09:15,230
My my car models and jeep here.

116
00:09:16,850 --> 00:09:17,720
Princess.

117
00:09:18,620 --> 00:09:19,430
You.

118
00:09:20,180 --> 00:09:23,360
You have a jeep here.

119
00:09:23,900 --> 00:09:28,460
And at the break statement here, break here.

120
00:09:28,460 --> 00:09:30,830
And then we're going to write.

121
00:09:31,650 --> 00:09:32,640
The default.

122
00:09:33,530 --> 00:09:35,420
Here's the fault.

123
00:09:40,010 --> 00:09:43,220
Here the false statement print.

124
00:09:46,390 --> 00:09:47,350
Plaintiffs.

125
00:09:48,960 --> 00:09:51,090
Error here, for example.

126
00:09:52,020 --> 00:09:53,250
User error.

127
00:09:54,630 --> 00:09:55,440
Unknown.

128
00:09:55,650 --> 00:09:56,550
Unknown.

129
00:09:57,560 --> 00:09:58,190
In.

130
00:10:01,890 --> 00:10:05,730
Unknown make or right model.

131
00:10:06,150 --> 00:10:09,540
No model here and.

132
00:10:10,810 --> 00:10:11,410
At.

133
00:10:12,060 --> 00:10:12,320
Pain.

134
00:10:12,900 --> 00:10:13,590
So.

135
00:10:16,560 --> 00:10:19,560
But let's now explain this clause here.

136
00:10:19,560 --> 00:10:28,200
The we create the enumeration class, declares the enumeration to type my car models, which you use

137
00:10:28,200 --> 00:10:32,520
to initialize my car models to Ferrari.

138
00:10:32,730 --> 00:10:42,570
So the switch statement here values the condition race to determine which condition to hand to control

139
00:10:42,570 --> 00:10:42,750
to.

140
00:10:42,780 --> 00:10:51,780
So because your hardcoded this to the Ferrari earlier in this code, as you can see here execution transfers

141
00:10:51,900 --> 00:10:52,860
to.

142
00:10:53,980 --> 00:10:54,820
Here.

143
00:10:55,790 --> 00:10:56,540
Ops before.

144
00:10:56,600 --> 00:11:01,270
Actually, we forgot to write the Ferrari here after Renault's.

145
00:11:01,490 --> 00:11:02,540
I'm sorry for it.

146
00:11:02,810 --> 00:11:04,580
Let's add case.

147
00:11:05,630 --> 00:11:07,790
My car models Ferrari.

148
00:11:09,380 --> 00:11:11,030
Here, print F.

149
00:11:12,160 --> 00:11:14,290
You have a Ferrari.

150
00:11:15,580 --> 00:11:15,990
Here.

151
00:11:16,830 --> 00:11:19,500
So and execution.

152
00:11:21,260 --> 00:11:24,860
Just let's add break here so.

153
00:11:27,420 --> 00:11:30,180
Because you hardcoded this.

154
00:11:32,580 --> 00:11:35,280
Ferrari error in this code.

155
00:11:36,030 --> 00:11:39,060
The execution here transfers to this Ferrari.

156
00:11:39,630 --> 00:11:44,190
So which prints you to You have a Ferrari.

157
00:11:45,560 --> 00:11:52,580
So the break here, the break here terminates the switch statement.

158
00:11:52,580 --> 00:11:58,880
So the default condition that this here is safety feature.

159
00:11:58,880 --> 00:12:08,000
So if someone adds a new race value or new my new my car models value to the enumeration class, you

160
00:12:08,000 --> 00:12:14,900
will detect that unknown raise to runtime and print an error message.

161
00:12:14,900 --> 00:12:26,990
So try setting this my car race models or racing models to different values and let's see how the output

162
00:12:26,990 --> 00:12:27,490
change.

163
00:12:27,500 --> 00:12:31,760
So firstly I want to compile code and run here.

164
00:12:33,130 --> 00:12:40,050
And as you can see here, we got an output that says you have an you have a Ferrari.

165
00:12:40,060 --> 00:12:43,810
So let's let's change this Ferrari to BMW here.

166
00:12:44,770 --> 00:12:51,820
And we will get and this case executes and we got you have a BMW.

167
00:12:51,820 --> 00:12:58,180
So let's add another make a model here, for example.

168
00:13:00,270 --> 00:13:02,820
With the GMC here.

169
00:13:04,400 --> 00:13:06,770
And use this GMC.

170
00:13:08,000 --> 00:13:12,800
And here, as you can see here, we got an user error.

171
00:13:12,830 --> 00:13:24,830
As you can see, we got printed this because we didn't this defined this GMC on this switch statement.
