1 00:00:00,450 --> 00:00:03,260 Plus plus clearance sup response. 2 00:00:03,330 --> 00:00:05,700 Let me explain what's going on. 3 00:00:05,700 --> 00:00:10,820 For the first time that this group is going to be executed the value of this response variable is zero. 4 00:00:10,820 --> 00:00:11,290 OK. 5 00:00:11,460 --> 00:00:18,930 And this loop is going to be executed onto the value of this response to valuable is less than the value 6 00:00:18,930 --> 00:00:22,030 of the land of these people rates every day. 7 00:00:22,040 --> 00:00:23,150 So as you can see here. 8 00:00:23,210 --> 00:00:36,350 So let's actually see what's the length of these people rates are 3 1 2 3 4 5 6 7 8 9 10 11 12 13. 9 00:00:36,420 --> 00:00:40,610 So the length of these people rates really is 15. 10 00:00:40,620 --> 00:00:41,060 OK. 11 00:00:41,160 --> 00:00:48,050 And here you are saying that until the value of this response variable is less than 15. 12 00:00:48,230 --> 00:00:51,200 OK execute this for loop here. 13 00:00:51,540 --> 00:00:57,680 So by the time that the value of the respond value reaches number six. 14 00:00:57,680 --> 00:01:05,190 OK That's number six is going to actually go inside of these brackets here and then it's going to actually 15 00:01:05,190 --> 00:01:11,790 go inside of this occurrence Aure and then it's going at it it wants to actually access the value that 16 00:01:11,790 --> 00:01:17,040 is inside of the index 6 index number six of these three. 17 00:01:17,130 --> 00:01:21,200 So we don't have index number six in this area here. 18 00:01:21,300 --> 00:01:21,720 OK. 19 00:01:21,840 --> 00:01:28,080 So we cannot actually access the value that is inside of the index number six of this very ok because 20 00:01:28,110 --> 00:01:33,710 as you can see these are the values of these are these are the indexes of this houri. 21 00:01:33,730 --> 00:01:33,980 OK. 22 00:01:34,080 --> 00:01:36,800 0 1 2 3 4 5. 23 00:01:36,890 --> 00:01:37,350 We cannot. 24 00:01:37,410 --> 00:01:43,220 You can only access the values that are inside of only these indexes. 25 00:01:43,230 --> 00:01:43,700 OK. 26 00:01:43,890 --> 00:01:47,060 So index number 6 doesn't exist as a result. 27 00:01:47,100 --> 00:01:53,820 You actually see this error here Arey out of bounds exception and that's why our application actually 28 00:01:53,820 --> 00:01:54,580 crashed. 29 00:01:54,720 --> 00:01:55,410 OK. 30 00:01:55,860 --> 00:02:02,400 So in order to solve this error here first of all it naturally comment out this these numbers here and 31 00:02:02,400 --> 00:02:09,550 here inside of these brackets we just need to refer to the name of these people at rates Aure people 32 00:02:09,850 --> 00:02:14,450 rates are cheap brackets keep people rates up. 33 00:02:14,470 --> 00:02:16,220 Respond. 34 00:02:17,260 --> 00:02:17,850 OK. 35 00:02:18,130 --> 00:02:22,340 And in this way it's going to actually go inside these people rates Ali. 36 00:02:22,490 --> 00:02:23,340 OK. 37 00:02:23,380 --> 00:02:30,070 And then it's going to actually give me the value that is inside of these or respond index. 38 00:02:30,070 --> 00:02:35,560 So for example for the first time that this group is going to be executed and the value of this respond 39 00:02:35,560 --> 00:02:36,520 valuable is zero. 40 00:02:36,520 --> 00:02:37,170 OK. 41 00:02:37,300 --> 00:02:40,810 So here for example the value of this response variable is zero. 42 00:02:40,810 --> 00:02:45,040 People rates Sub Zero is going to ask you to give me devalue number one. 43 00:02:45,220 --> 00:02:45,900 OK. 44 00:02:46,270 --> 00:02:51,720 And that number one is going to actually replace this piece of code here. 45 00:02:51,970 --> 00:02:57,780 As you can see so here we have we have actually that actually create a comment here number one. 46 00:02:57,880 --> 00:02:58,540 OK. 47 00:02:58,840 --> 00:03:01,300 So this value is number one now. 48 00:03:01,330 --> 00:03:05,080 So here we have plus plus occurrence number one. 49 00:03:05,140 --> 00:03:06,590 Plus inside the brackets. 50 00:03:06,610 --> 00:03:07,350 OK. 51 00:03:07,360 --> 00:03:10,300 So it's going to go inside the occurrence Aure here. 52 00:03:10,330 --> 00:03:18,400 As you can see and it is going to give me the value that is inside of the index number of one of these 53 00:03:18,490 --> 00:03:19,110 arii. 54 00:03:19,300 --> 00:03:19,860 OK. 55 00:03:19,900 --> 00:03:25,570 And then it's going to actually increment that value by one and then it's going to actually return that 56 00:03:25,570 --> 00:03:26,680 value to me. 57 00:03:26,710 --> 00:03:27,180 OK. 58 00:03:27,370 --> 00:03:32,350 Plus plus occurrence Sup people rates some respond. 59 00:03:32,770 --> 00:03:34,960 OK let me you to explain again here. 60 00:03:35,170 --> 00:03:41,410 So for the second time that this loop is going to be executed the value of this respon variable is number 61 00:03:41,440 --> 00:03:41,620 one. 62 00:03:41,640 --> 00:03:42,310 OK. 63 00:03:42,740 --> 00:03:48,260 So this month plus plus here as you can see it is going to actually increment the value of this respond 64 00:03:48,290 --> 00:03:51,910 variable by one after each execution of this world. 65 00:03:52,090 --> 00:03:55,050 So now the value of this response valuable is one. 66 00:03:55,330 --> 00:03:57,620 So now it's going to go inside of this for a loop. 67 00:03:57,820 --> 00:04:01,550 And here the value of this respon variable is one. 68 00:04:01,570 --> 00:04:04,260 So here we have people rates sub 1. 69 00:04:04,330 --> 00:04:04,980 OK. 70 00:04:05,050 --> 00:04:11,290 So it's going to go inside of the index number of one of these people rates are the index and the value 71 00:04:11,290 --> 00:04:14,660 of the index number of one of these people rates our rate is fourth. 72 00:04:14,710 --> 00:04:15,140 OK. 73 00:04:15,220 --> 00:04:16,600 Disvalue. 74 00:04:16,600 --> 00:04:20,440 So here we have number four inside of the brackets. 75 00:04:20,470 --> 00:04:24,210 So now we have plus plus occurrence Suppe number four. 76 00:04:24,250 --> 00:04:24,930 OK. 77 00:04:24,940 --> 00:04:29,900 So now we have number four inside of the brackets of these Acura unsorry. 78 00:04:30,280 --> 00:04:36,470 So now it's going to go inside of the index number for all of these occurrence. 79 00:04:36,760 --> 00:04:39,040 And then it's going to actually increment. 80 00:04:39,040 --> 00:04:43,310 That's where you Boivin and then it's going to return that value to me. 81 00:04:43,650 --> 00:04:44,580 OK. 82 00:04:45,250 --> 00:04:47,300 So hopefully that makes sense. 83 00:04:47,470 --> 00:04:52,240 And let's actually do our project again and see what happens. 84 00:04:52,240 --> 00:04:59,110 So now as you can see our application launched successfully and here we can see the values here. 85 00:04:59,110 --> 00:05:02,200 Rates number of stars here as you can see. 86 00:05:02,200 --> 00:05:09,550 So as you can see here for the rate number one we have two people with one star value and for the rate 87 00:05:09,550 --> 00:05:14,180 number two we have two people with two stars of value we have. 88 00:05:14,260 --> 00:05:20,320 And for the rate number three for example we have two people we are freestylers value for their rates. 89 00:05:20,320 --> 00:05:24,840 Number four we have free people with a forestalls value. 90 00:05:24,970 --> 00:05:30,570 And for the right for the right for example Number five we have four people need five stars value. 91 00:05:30,580 --> 00:05:31,150 OK. 92 00:05:31,630 --> 00:05:37,930 So now as you can see here you are actually reading the values that are actually inside of these people 93 00:05:37,930 --> 00:05:38,380 rates. 94 00:05:38,800 --> 00:05:39,300 Okay. 95 00:05:39,370 --> 00:05:44,780 And as you can see here inside of these people rates are a you have this value here five. 96 00:05:45,010 --> 00:05:46,560 Again we have this value 5. 97 00:05:46,560 --> 00:05:52,720 Here again we have this value of five here and this value five here as you can see for the rate number 98 00:05:52,720 --> 00:05:53,390 five. 99 00:05:53,410 --> 00:05:56,530 We have four people with five star value. 100 00:05:56,530 --> 00:05:57,020 OK. 101 00:05:57,130 --> 00:06:00,710 So if your actual reading devalues that are actually inside of this area. 102 00:06:00,790 --> 00:06:05,890 So let's I should go I can say this content others like me in that example and here let's actually click 103 00:06:05,920 --> 00:06:12,950 on this clear cut chest here and essentially change the text of this takes you to a number of people. 104 00:06:12,950 --> 00:06:13,310 OK. 105 00:06:13,390 --> 00:06:14,640 Number of people. 106 00:06:14,730 --> 00:06:20,350 And inside of this mine activity that will here as you can see it's actually on our project again and 107 00:06:20,350 --> 00:06:21,400 see what happens. 108 00:06:21,400 --> 00:06:26,630 So as you can see here now are up our application is actually running on this emulator. 109 00:06:26,980 --> 00:06:29,230 And here we can see these values here. 110 00:06:29,220 --> 00:06:29,730 Okay. 111 00:06:29,800 --> 00:06:35,000 So we have for the rates number one we have for example to people with monster value and so on. 112 00:06:35,000 --> 00:06:35,760 OK. 113 00:06:36,160 --> 00:06:37,910 So hopefully that makes sense. 114 00:06:38,220 --> 00:06:44,230 And here let's actually add another value to these people rates right here. 115 00:06:44,230 --> 00:06:44,740 OK. 116 00:06:44,800 --> 00:06:52,310 So here just putting a comma here and here just you can actually put number 6 here for example. 117 00:06:52,630 --> 00:06:56,960 And now let's actually run our project and see what happens. 118 00:06:57,120 --> 00:06:59,290 That may actually deleted this comment here. 119 00:06:59,710 --> 00:07:01,420 And let's actually do our project. 120 00:07:01,450 --> 00:07:04,790 So as you can see here our application is actually crashed. 121 00:07:04,810 --> 00:07:05,390 OK. 122 00:07:05,480 --> 00:07:12,660 Unfortunately at 17 has stopped and this means that that our application actually crashed and we have 123 00:07:12,660 --> 00:07:13,930 a problem in our codes. 124 00:07:13,950 --> 00:07:14,500 OK. 125 00:07:14,670 --> 00:07:21,780 So as you can see here inside the log it says don't bother to learn that Arey index out of bounds exception. 126 00:07:21,780 --> 00:07:27,100 Again if you're actually getting the same error that we got earlier in this tutorial. 127 00:07:27,150 --> 00:07:28,510 OK Len. 128 00:07:28,570 --> 00:07:30,930 Len for six index six. 129 00:07:30,930 --> 00:07:31,600 OK. 130 00:07:31,770 --> 00:07:37,500 So in the main activity that you will find here actually assigned another value to these people rates 131 00:07:37,890 --> 00:07:40,380 are a hit as you can see this is number six. 132 00:07:40,380 --> 00:07:40,870 OK. 133 00:07:41,040 --> 00:07:44,400 Let me ask you to explain what's going on here inside of this for loop. 134 00:07:44,400 --> 00:07:44,880 OK. 135 00:07:45,090 --> 00:07:51,660 So for example inside of this for loop I actually created an integer number and it has a variable. 136 00:07:51,750 --> 00:07:52,470 OK. 137 00:07:52,890 --> 00:07:55,690 And the name of this integer variable is respon OK. 138 00:07:55,710 --> 00:07:58,390 And then I assign the value zero to this variable. 139 00:07:58,470 --> 00:08:03,810 And here I actually created a condition that actually determines that whether this group is going to 140 00:08:03,810 --> 00:08:05,310 be executed or not. 141 00:08:05,390 --> 00:08:06,090 OK. 142 00:08:06,330 --> 00:08:10,680 So for example the value of this response variable is for that for the first time is zero. 143 00:08:10,680 --> 00:08:16,410 This loop is going to be executed until the value of this responder variable is less than the value 144 00:08:16,410 --> 00:08:19,520 of the land of these people rates are that people rates. 145 00:08:19,590 --> 00:08:25,200 OK so now the value of the length of these people rates rate is 14. 146 00:08:25,340 --> 00:08:25,910 OK. 147 00:08:26,800 --> 00:08:32,250 So now inside of this for loop for the first time the value of this respon value bet is zero. 148 00:08:32,320 --> 00:08:32,770 OK. 149 00:08:32,860 --> 00:08:33,690 It's going to actually go. 150 00:08:33,730 --> 00:08:39,910 This value is going to be inside of the brackets of these people rates are here as you can see people 151 00:08:39,910 --> 00:08:41,050 rates respond. 152 00:08:41,230 --> 00:08:45,020 So it's going to actually go inside of the index zero of these people rates away. 153 00:08:45,100 --> 00:08:49,410 So the value of the index zero of these people it really is number one. 154 00:08:49,630 --> 00:08:50,080 OK. 155 00:08:50,230 --> 00:08:52,420 So it's going to give me the value. 156 00:08:52,420 --> 00:08:53,710 Number one here. 157 00:08:53,890 --> 00:08:59,980 So now we have number the value number of one inside the brackets of this occurrence. 158 00:09:00,210 --> 00:09:00,790 OK. 159 00:09:01,240 --> 00:09:05,060 So plus plus carrots sup number one. 160 00:09:05,140 --> 00:09:05,670 OK. 161 00:09:05,920 --> 00:09:11,980 So the value that is inside of the index number of one of these occasions Arey is for example zero. 162 00:09:12,070 --> 00:09:12,670 OK. 163 00:09:12,940 --> 00:09:15,580 So that is going to actually increment that value by one. 164 00:09:15,700 --> 00:09:16,090 OK. 165 00:09:16,120 --> 00:09:20,670 And this group is going to actually continue executing until it reaches this value. 166 00:09:20,680 --> 00:09:21,030 OK. 167 00:09:21,040 --> 00:09:26,270 Number six this number six is the last value that is inside of the people rates Ali. 168 00:09:26,280 --> 00:09:26,760 Ali. 169 00:09:26,770 --> 00:09:27,380 OK. 170 00:09:27,430 --> 00:09:33,070 So let's actually count the values that are actually inside of the people rates are a zero. 171 00:09:33,250 --> 00:09:33,820 OK. 172 00:09:34,030 --> 00:09:50,110 One two three four five six seven eight nine 10 11 12 13 OK. 173 00:09:50,200 --> 00:09:56,240 So this value is actually at the index Fourteen of these people rates are a. 174 00:09:56,430 --> 00:10:02,920 Ok this number six is actually at the index fifteen of these people rates are a.
