1
00:00:01,340 --> 00:00:08,870
The switch statements transfers control to one of several statements depending on the value of a condition,

2
00:00:08,870 --> 00:00:13,910
so which evaluates to either an integer or enumeration type.

3
00:00:14,750 --> 00:00:22,290
The switch keyword denotes a switch statement, so the switch statements provide conditional branching.

4
00:00:22,310 --> 00:00:30,890
When a switch statement executes control, transfer to the case fitting to the condition or to a default

5
00:00:30,890 --> 00:00:34,370
condition if no case matches the condition expression.

6
00:00:34,370 --> 00:00:42,440
So the case keyword denotes a case where the default keyword denotes the default condition.

7
00:00:42,680 --> 00:00:51,860
Somewhat confusingly, execution will continue until the end of the switch statement or to the break

8
00:00:51,890 --> 00:00:52,760
keyword.

9
00:00:52,760 --> 00:01:00,740
So you will almost you will always find a break at each end of each description and condition.

10
00:01:00,740 --> 00:01:02,630
So let's create an example.

11
00:01:02,720 --> 00:01:04,780
Switch statement, for example.

12
00:01:04,790 --> 00:01:05,690
Switch.

13
00:01:06,510 --> 00:01:07,020
Here.

14
00:01:07,020 --> 00:01:08,520
This is our condition.

15
00:01:08,520 --> 00:01:19,950
And then we have a cases case expression here, or you can write case like that in this and then handle

16
00:01:19,950 --> 00:01:22,020
a case here.

17
00:01:22,020 --> 00:01:26,220
And then you will add the here.

18
00:01:28,250 --> 00:01:35,240
And then you will add the break here after this curly braces, you will add break, which I will explain

19
00:01:35,240 --> 00:01:36,170
why.

20
00:01:36,350 --> 00:01:38,630
Uh, what what are these here?

21
00:01:38,810 --> 00:01:45,110
So then, for example, let's add second case case expression to.

22
00:01:46,560 --> 00:01:47,280
Here.

23
00:01:47,940 --> 00:01:51,960
And then let's add here.

24
00:01:52,770 --> 00:01:53,610
Handle.

25
00:01:53,640 --> 00:01:56,640
Handle a case two here.

26
00:01:56,640 --> 00:02:00,930
And then as always, we do in switch statements.

27
00:02:01,950 --> 00:02:04,650
We do break here.

28
00:02:04,770 --> 00:02:11,730
And after that, after that, we have a default keyword in switch statement.

29
00:02:11,730 --> 00:02:13,580
So let's write this as well.

30
00:02:13,590 --> 00:02:19,530
Default keyword, which will explain what is default handle.

31
00:02:19,530 --> 00:02:24,330
The default keyword is default case here.

32
00:02:25,130 --> 00:02:34,700
So now I will begin to explain this, what these keywords are and how this switch statement.

33
00:02:35,570 --> 00:02:37,430
Switch statement structure works.

34
00:02:37,460 --> 00:02:41,210
So let's start with the switch keyword.

35
00:02:41,210 --> 00:02:48,710
So switch keyword followed by the condition in parentheses here.

36
00:02:49,650 --> 00:02:52,050
Actually, we don't need to parentheses here.

37
00:02:52,800 --> 00:02:53,880
It's useless.

38
00:02:54,570 --> 00:02:58,860
So switch statement followed by this condition.

39
00:02:58,860 --> 00:03:00,300
Parentheses here.

40
00:03:01,450 --> 00:03:03,600
So I'll switch begins with this.

41
00:03:03,610 --> 00:03:08,290
You can't you just can't write a case and then switch.

42
00:03:08,290 --> 00:03:13,230
So you have to do switch and then cases and after that default here.

43
00:03:13,320 --> 00:03:19,480
So every switch statement starts with switch and condition here.

44
00:03:19,480 --> 00:03:32,500
And then each case begins with the case keyword here, followed by the cases enumeration or integral

45
00:03:32,500 --> 00:03:33,340
value.

46
00:03:34,420 --> 00:03:38,200
If condition equals here.

47
00:03:38,740 --> 00:03:40,240
For example, case one.

48
00:03:40,390 --> 00:03:49,810
For example, the code in the block containing here handle case here will execute after each statement.

49
00:03:49,810 --> 00:03:54,680
Following a case here, you place a break keyword.

50
00:03:54,700 --> 00:04:04,720
So if condition matches none of the case, the default case here, as you can see here, is executes.

51
00:04:06,790 --> 00:04:09,200
So I want to add something here.

52
00:04:09,220 --> 00:04:17,470
The braces here, uh, enclosing each case are optional, but I highly recommend this.

53
00:04:17,500 --> 00:04:21,010
Without them, you will sometimes get surprising behavior.

54
00:04:21,010 --> 00:04:24,190
So always add these curly braces.

55
00:04:25,000 --> 00:04:33,490
But in the technical sides, technical view, it's not mandatory, but highly recommended.

56
00:04:34,230 --> 00:04:39,720
So let's create a switch statement with the enumeration class.

57
00:04:40,050 --> 00:04:41,530
So I'm going to delete this.

58
00:04:41,550 --> 00:04:43,410
You don't need this here.

59
00:04:44,370 --> 00:04:45,300
And here.

60
00:04:45,900 --> 00:04:47,880
So let's create an first.

61
00:04:47,880 --> 00:04:50,210
Let's create an enum class here.

62
00:04:50,220 --> 00:04:51,200
For example.

63
00:04:51,210 --> 00:04:52,860
Enum class.

64
00:04:54,170 --> 00:04:56,300
Here race.

65
00:04:57,370 --> 00:04:59,200
Or car models.

66
00:05:00,820 --> 00:05:04,570
For my car models here.

67
00:05:04,930 --> 00:05:06,790
I will explain all of these codes.

68
00:05:07,240 --> 00:05:13,030
Here, for example, BMW, BMW, Mercedes.

69
00:05:14,990 --> 00:05:15,680
Burnout.

70
00:05:17,400 --> 00:05:18,000
Ferrari.

71
00:05:20,740 --> 00:05:21,790
Volkswagen.

72
00:05:22,650 --> 00:05:25,720
Port here cheap.

73
00:05:26,160 --> 00:05:28,050
And I think that's enough.

74
00:05:30,110 --> 00:05:33,350
So as you can see, one, two, three, four, five, six, seven.

75
00:05:33,350 --> 00:05:35,540
We have seven car models here.

76
00:05:35,750 --> 00:05:39,740
So in main statement, let's write our switch.

77
00:05:40,220 --> 00:05:41,780
Switch case statements here.

78
00:05:41,900 --> 00:05:46,160
So let's create the object race here.

79
00:05:47,130 --> 00:05:49,260
Or my car models.

80
00:05:49,260 --> 00:05:50,490
My car models.

81
00:05:51,810 --> 00:05:57,300
Okay, so cars here or my cars.

82
00:05:58,110 --> 00:06:00,910
Equals my car models here.

83
00:06:00,930 --> 00:06:07,380
This operator and for example, Ferrari.

84
00:06:10,330 --> 00:06:14,620
So then I will explain all of these codes as I do.

85
00:06:14,620 --> 00:06:17,880
Always switch here.

86
00:06:17,890 --> 00:06:18,700
Switch.

87
00:06:20,160 --> 00:06:27,150
As you can see, our integrated development environment automatically created this braces here.

88
00:06:27,150 --> 00:06:38,240
So now we will give the switch here, my cars, because we will use this in class here and we will use

89
00:06:38,490 --> 00:06:39,150
class members.

90
00:06:39,150 --> 00:06:48,510
So mainly firstly we will give my car as a parameter and then we will write our case and default statements.

91
00:06:49,430 --> 00:06:51,110
So let's start with.

92
00:06:53,250 --> 00:06:56,500
Let's let's follow this order here.

93
00:06:56,550 --> 00:06:58,830
So switch case.

94
00:06:58,860 --> 00:07:00,300
Switch case.

95
00:07:01,330 --> 00:07:02,460
Um, switch.

96
00:07:02,670 --> 00:07:04,590
Case here.

97
00:07:05,400 --> 00:07:08,860
Were my cars, my car models.

98
00:07:08,880 --> 00:07:11,460
For example, BMW and then.

99
00:07:12,630 --> 00:07:14,120
Here curly braces.

100
00:07:14,130 --> 00:07:25,020
If the case is BMW, you have a BMW and then we will break code.

101
00:07:25,800 --> 00:07:31,770
Break this case statement after the curly braces here.

102
00:07:31,860 --> 00:07:34,650
And let's add another case here.

103
00:07:35,100 --> 00:07:41,100
Case, my car models, we have the Mercedes here.

104
00:07:41,430 --> 00:07:54,150
And then print if you have a mercedes Mercedes Benz here and then break our code.

105
00:07:54,630 --> 00:07:55,550
Break our code.

106
00:07:55,560 --> 00:08:00,770
Add another case because we have six variables here.

107
00:08:00,780 --> 00:08:06,660
Then we have a renowned my car models renowned here.

108
00:08:06,660 --> 00:08:13,720
Print f you have a renowned here and then break this as well.

109
00:08:14,910 --> 00:08:16,590
Uh, well, okay.

110
00:08:16,890 --> 00:08:17,520
Yeah.

111
00:08:18,360 --> 00:08:19,740
Uh, what's the problem here?

112
00:08:19,770 --> 00:08:20,430
Yeah.

113
00:08:21,180 --> 00:08:21,990
Fix that.

114
00:08:22,920 --> 00:08:26,990
And my car models renowned.

115
00:08:27,000 --> 00:08:30,090
We have a well here we have renowned.

116
00:08:30,090 --> 00:08:31,920
And let's add Volkswagen.

117
00:08:33,340 --> 00:08:35,380
Print f you.

118
00:08:36,340 --> 00:08:41,460
You have a Volkswagen and then break this code.

119
00:08:41,470 --> 00:08:42,820
I'll also here.

120
00:08:42,820 --> 00:08:51,280
And lastly, we have two car models, case my car models here.

121
00:08:52,030 --> 00:08:54,610
Let's add Ford and.

122
00:08:55,330 --> 00:08:55,960
Here.

123
00:08:56,440 --> 00:09:00,310
Print f you have a fourth.

124
00:09:03,140 --> 00:09:04,100
Break.

125
00:09:04,880 --> 00:09:08,450
And lastly, my car mode.

126
00:09:08,530 --> 00:09:09,050
Oops.

127
00:09:10,150 --> 00:09:15,190
My my car models and jeep here.

128
00:09:16,750 --> 00:09:19,300
Print f you.

129
00:09:20,140 --> 00:09:23,350
You have a jeep here.

130
00:09:23,590 --> 00:09:27,120
And add the brake statement here.

131
00:09:27,220 --> 00:09:30,760
Break here and then we're going to write.

132
00:09:31,520 --> 00:09:32,540
Did default.

133
00:09:33,430 --> 00:09:34,150
Here.

134
00:09:34,150 --> 00:09:35,380
The fault.

135
00:09:36,900 --> 00:09:37,290
Oops.

136
00:09:39,820 --> 00:09:43,180
Here the false statement print.

137
00:09:46,320 --> 00:09:47,220
Print f.

138
00:09:48,590 --> 00:09:51,020
Uh, error here, for example.

139
00:09:52,010 --> 00:09:53,210
User error.

140
00:09:54,570 --> 00:09:55,200
Unknown.

141
00:09:55,670 --> 00:09:56,450
Unknown.

142
00:09:57,550 --> 00:09:58,090
UN.

143
00:10:01,820 --> 00:10:05,690
Unknown make here or let's write model.

144
00:10:05,840 --> 00:10:09,560
Unknown model here and.

145
00:10:10,740 --> 00:10:11,340
Add.

146
00:10:12,050 --> 00:10:12,860
And press here.

147
00:10:12,860 --> 00:10:13,520
So.

148
00:10:16,490 --> 00:10:19,490
But let's now explain this clause here.

149
00:10:19,490 --> 00:10:29,090
The we create the enumeration class declares the enumeration type my car models, which you use to initialize

150
00:10:29,090 --> 00:10:32,510
my car models to Ferrari.

151
00:10:32,540 --> 00:10:42,500
So the switch statement here evaluates the condition race to determine which condition to hand to control

152
00:10:42,500 --> 00:10:42,710
to.

153
00:10:42,710 --> 00:10:51,770
So because your hard coded this to the Ferrari earlier in this code as you can see here execution transfers

154
00:10:51,770 --> 00:10:52,820
to.

155
00:10:53,640 --> 00:10:54,660
Uh, here.

156
00:10:55,720 --> 00:10:56,500
Ops before.

157
00:10:56,530 --> 00:11:00,740
Actually, we forgot to write the Ferrari here after.

158
00:11:01,210 --> 00:11:02,590
Yeah, I'm sorry for it.

159
00:11:02,620 --> 00:11:04,510
Let's add case.

160
00:11:05,530 --> 00:11:09,900
My car models Ferrari here.

161
00:11:09,910 --> 00:11:10,960
Print f.

162
00:11:12,000 --> 00:11:14,220
You have a Ferrari?

163
00:11:15,300 --> 00:11:15,960
Here.

164
00:11:16,700 --> 00:11:17,300
So.

165
00:11:17,840 --> 00:11:19,430
And execution.

166
00:11:21,190 --> 00:11:24,280
Just our let's add break here.

167
00:11:24,280 --> 00:11:24,730
So.

168
00:11:27,200 --> 00:11:30,110
Because you hardcoded this.

169
00:11:32,240 --> 00:11:35,210
Uh, Ferrari in this code.

170
00:11:35,900 --> 00:11:39,080
The execution here transfers to this Ferrari.

171
00:11:39,380 --> 00:11:42,230
So which prints you to.

172
00:11:42,230 --> 00:11:44,270
You have a Ferrari?

173
00:11:45,430 --> 00:11:47,800
So the break here.

174
00:11:48,520 --> 00:11:52,510
The break here terminates the switch statement.

175
00:11:52,510 --> 00:11:58,810
So the default condition at this here is safety feature.

176
00:11:58,810 --> 00:12:07,930
So if someone adds a new race value or a new my new my car models value to the enumeration class, you

177
00:12:07,930 --> 00:12:14,830
will detect that unknown race to runtime and print an error message.

178
00:12:14,830 --> 00:12:26,920
So try setting this my car race models racing models to different values and let's see how the output

179
00:12:26,920 --> 00:12:27,400
changes.

180
00:12:27,400 --> 00:12:31,720
So firstly I want to compile code and run here.

181
00:12:33,030 --> 00:12:39,960
And as you can see here, we got an output that says you have an you have a Ferrari.

182
00:12:39,960 --> 00:12:43,830
So let's let's change this Ferrari to BMW here.

183
00:12:44,640 --> 00:12:51,750
And we will get and this case executes and we got the you have a BMW.

184
00:12:51,750 --> 00:12:58,140
So let's add another make model here, for example.

185
00:13:00,290 --> 00:13:02,810
Let's add GMC here.

186
00:13:04,300 --> 00:13:06,430
And use this GMC.

187
00:13:07,720 --> 00:13:12,730
And here, as you can see here, we got an a user error.

188
00:13:12,760 --> 00:13:24,790
As you can see, we got a printed this because we didn't define this GMC on this switch statement.
