1 00:00:00,410 --> 00:00:04,630 And now let's actually go ahead and add some lines of code here. 2 00:00:04,640 --> 00:00:12,180 So now I even tried to the output the size of these are Auret to the screen after actually after adding 3 00:00:12,180 --> 00:00:13,190 values to these. 4 00:00:13,430 --> 00:00:20,550 OK so here first of all I refer to the name of this text you object to the aerialist capacity after 5 00:00:20,640 --> 00:00:27,780 adding values that said text anemones that size plus two double quotes so that this value is actually 6 00:00:27,780 --> 00:00:32,170 converted to a string value and then we can actually see that value on the screen. 7 00:00:32,310 --> 00:00:35,360 So now let's actually run our project and see what happens. 8 00:00:35,450 --> 00:00:36,040 OK. 9 00:00:36,120 --> 00:00:39,860 Now as you can see our application is running on this emulator. 10 00:00:40,050 --> 00:00:46,540 And as you can see it's the capacity of our aerialist after adding values is number 7. 11 00:00:46,710 --> 00:00:47,250 OK. 12 00:00:47,340 --> 00:00:52,240 So we have seven values inside of these animals right now. 13 00:00:52,310 --> 00:00:52,960 OK. 14 00:00:53,400 --> 00:00:58,620 So here let's actually create a method inside of this main activity class. 15 00:00:58,620 --> 00:01:05,040 So after the end in Curlylocks of this uncreate method let's actually create another method here. 16 00:01:05,100 --> 00:01:05,450 OK. 17 00:01:05,510 --> 00:01:05,840 OK. 18 00:01:05,850 --> 00:01:10,560 Now I'm going to actually paste this method here and then I'll explain to you what's going on here. 19 00:01:10,710 --> 00:01:11,290 OK. 20 00:01:11,550 --> 00:01:16,830 So as you can see here this is my method that they actually pasted here inside of this main activity 21 00:01:16,830 --> 00:01:17,610 class. 22 00:01:17,640 --> 00:01:24,330 So the access modifier of this if it is public the return type of this method is Voyt and the name of 23 00:01:24,330 --> 00:01:30,460 this method is output the aerialist values to the screen by using enhanced for loop. 24 00:01:30,540 --> 00:01:31,200 OK. 25 00:01:31,500 --> 00:01:37,720 And this method actually accepts two arguments and the first argument is actually after Aurelia's strange 26 00:01:38,100 --> 00:01:40,130 the name of this argument is values. 27 00:01:40,260 --> 00:01:46,640 And then the second argument is actually of type takes few and the name of this argument is takes you 28 00:01:46,650 --> 00:01:47,010 here. 29 00:01:47,040 --> 00:01:47,800 OK. 30 00:01:48,060 --> 00:01:54,370 And inside of the Smurfit as you can see first of all in 1960 I created the string variable. 31 00:01:54,390 --> 00:01:56,180 I declare this variable here. 32 00:01:56,400 --> 00:02:00,480 And then I'd actually I didn't instantiate this variable here. 33 00:02:00,480 --> 00:02:01,000 OK. 34 00:02:01,230 --> 00:02:02,800 And I created a for loop. 35 00:02:02,880 --> 00:02:03,580 OK. 36 00:02:04,080 --> 00:02:05,490 And enhanced for loop. 37 00:02:05,490 --> 00:02:09,180 I created actually a string variable called the value. 38 00:02:09,480 --> 00:02:13,530 And now you want to either rate over the values that are actually inside of this add a list. 39 00:02:13,530 --> 00:02:14,960 Here are key values. 40 00:02:15,210 --> 00:02:22,380 And now inside of this a for loop here as you can see I instantiated this all takes you a value and 41 00:02:22,690 --> 00:02:26,930 actually refers to the name of this takes you here that gettext that was. 42 00:02:27,090 --> 00:02:33,000 And then I assign this value to this old text view value and an inline 64. 43 00:02:33,000 --> 00:02:36,750 Are you referred to the name of this text you object that set text. 44 00:02:36,930 --> 00:02:40,890 All it takes you value plus value plus a space here. 45 00:02:41,000 --> 00:02:45,250 OK so now let's try to go back inside this uncreate method. 46 00:02:45,250 --> 00:02:49,840 Now let's actually add another value to these animals. 47 00:02:49,860 --> 00:02:50,120 OK. 48 00:02:50,130 --> 00:02:57,350 So animals darts at and inside of double quotes Let's actually type duck. 49 00:02:57,780 --> 00:02:58,760 OK. 50 00:02:58,860 --> 00:03:06,420 And now it's actually referred to the name of the Smurfette here on which foods are the frailest values 51 00:03:06,420 --> 00:03:07,050 to the screen. 52 00:03:07,080 --> 00:03:12,910 By using an enhanced for loop and this method actually accepts two arguments as you can see. 53 00:03:12,930 --> 00:03:16,880 So the first argument is actually of type and it really is strange. 54 00:03:17,010 --> 00:03:21,870 So now we have a list here as you can see animals. 55 00:03:22,410 --> 00:03:23,790 OK come on. 56 00:03:23,940 --> 00:03:26,600 And the second argument is actually offtake takes view. 57 00:03:26,640 --> 00:03:30,460 So I can just type anti-X the least values. 58 00:03:30,480 --> 00:03:34,610 Ok so now let's actually run our project and see what happens. 59 00:03:34,680 --> 00:03:35,010 OK. 60 00:03:35,010 --> 00:03:38,860 As you can see here now our application is running on this emulator. 61 00:03:39,060 --> 00:03:44,960 And here if we actually scroll to the left and here as you can see we can see this dog value here. 62 00:03:45,000 --> 00:03:45,610 OK. 63 00:03:45,780 --> 00:03:49,660 But here as you can see the capacity of Aurelia's after adding values is 7. 64 00:03:49,710 --> 00:03:50,210 OK. 65 00:03:50,430 --> 00:03:54,930 So here in line 49 I added another value to these animals at 8. 66 00:03:55,080 --> 00:04:02,580 So here I could actually just type in the Aurelia's capacity after adding values that said text animals 67 00:04:04,000 --> 00:04:07,670 are dot size plus two double quotes. 68 00:04:07,820 --> 00:04:13,110 That's actually run our project again and here as you can see our application is running on the simulator 69 00:04:13,200 --> 00:04:17,900 and here it says the capacity of analyst after adding values is 8. 70 00:04:17,940 --> 00:04:23,570 OK because we added these value this thug value to these are a hit as you can see here. 71 00:04:23,580 --> 00:04:24,390 OK. 72 00:04:24,750 --> 00:04:30,330 So hopefully this makes sense let's actually go back and say this our main activity that a fight here. 73 00:04:30,840 --> 00:04:36,970 But before that before adding any other lines of code here as you can see I created a for loop here. 74 00:04:37,200 --> 00:04:37,910 OK. 75 00:04:38,250 --> 00:04:43,650 And then I actually tried to output the values that are actually inside of this Aure to the screen. 76 00:04:43,650 --> 00:04:44,490 OK. 77 00:04:44,520 --> 00:04:51,330 And then I created this Smurfette here as you can see inside of this glass output the A list values 78 00:04:51,330 --> 00:04:53,570 to the screen by using enhanced for loop. 79 00:04:53,820 --> 00:04:59,450 And here I actually again called this method here kid in line 51. 80 00:04:59,920 --> 00:05:02,660 Here you want to out with the values of these animals. 81 00:05:02,680 --> 00:05:10,450 Ari to the screen and as you can see here I want to put those values to these text the at least values 82 00:05:10,480 --> 00:05:11,360 object. 83 00:05:11,440 --> 00:05:14,820 So here as you can see we've got our. 84 00:05:15,220 --> 00:05:23,230 As you can see this does actually go inside here as you can see lion tiger cat punter bear bear Fox 85 00:05:23,880 --> 00:05:27,220 lion again as you can see we can see those values are here. 86 00:05:27,230 --> 00:05:33,970 Lion Tiger-Cats and that's because we actually created this for live here and it was called the Smurfette 87 00:05:33,970 --> 00:05:34,600 here. 88 00:05:34,630 --> 00:05:35,270 OK. 89 00:05:35,290 --> 00:05:42,640 And it's going to actually put those values beside each other and here as you can see the flow of the 90 00:05:42,640 --> 00:05:45,140 program is going to try to execute this for a loop. 91 00:05:45,430 --> 00:05:49,620 And then here and then here here and here. 92 00:05:49,630 --> 00:05:50,270 OK. 93 00:05:50,530 --> 00:05:56,490 And we have to actually prevent these errors mistakes in our codes. 94 00:05:56,650 --> 00:06:01,120 So here we could actually comment out this line of code here. 95 00:06:01,360 --> 00:06:04,750 And if I actually did on my project again let's see what happens. 96 00:06:04,890 --> 00:06:08,850 And here as you can see we can see these values here only once. 97 00:06:08,860 --> 00:06:09,300 OK. 98 00:06:09,400 --> 00:06:10,690 Hopefully that makes sense. 99 00:06:10,690 --> 00:06:18,550 And as you can see here we can we can't see the tag value here because in this way the flow of the program 100 00:06:18,550 --> 00:06:24,010 only executes this for loop here and then it's going to execute this line of code and then it's going 101 00:06:24,010 --> 00:06:26,040 to actually execute this line of code here. 102 00:06:26,080 --> 00:06:26,730 OK. 103 00:06:26,950 --> 00:06:31,430 But as you can see the capacity of aerialist after adding values is 8. 104 00:06:31,450 --> 00:06:37,000 OK but we didn't actually tried to output this value to this screen yet. 105 00:06:37,000 --> 00:06:37,270 OK. 106 00:06:37,300 --> 00:06:40,170 Because we added this line of code after this for loop here. 107 00:06:40,270 --> 00:06:41,160 OK. 108 00:06:41,770 --> 00:06:49,960 So hopefully that makes sense and if we actually want to comment out this line of code here now I can 109 00:06:49,960 --> 00:06:52,030 actually uncomment this line of code here. 110 00:06:52,090 --> 00:06:54,850 And if I run on my project again let's see what happens. 111 00:06:54,880 --> 00:06:58,390 So now we can see our application is running on the simulator. 112 00:06:58,420 --> 00:07:04,690 And if you scroll to the left to the left as you can see we can see the stock value here and the capacity 113 00:07:04,690 --> 00:07:07,290 of Aurelia's after adding values is 8. 114 00:07:07,350 --> 00:07:11,460 OK so now let's actually add some lines of code here. 115 00:07:11,470 --> 00:07:14,830 So here I want to actually paste another line of code here. 116 00:07:15,220 --> 00:07:22,940 So as you can see here I want to actually add this value at index 0 of these animals Ali. 117 00:07:23,030 --> 00:07:23,760 OK. 118 00:07:23,950 --> 00:07:28,110 So here I just referred to the name of this Aure animals that I had. 119 00:07:28,240 --> 00:07:28,480 OK. 120 00:07:28,480 --> 00:07:33,660 And inside the apprentice's of this Meffert and I actually put the number zero. 121 00:07:33,700 --> 00:07:35,360 Here come the vault. 122 00:07:35,620 --> 00:07:42,420 So here I'm going to actually put this Avali evolve at index 0 of these arey. 123 00:07:42,520 --> 00:07:43,150 OK. 124 00:07:43,330 --> 00:07:50,690 So let's actually call the Smurfette here out foods the aerialist values to the screen. 125 00:07:50,920 --> 00:07:54,180 So here I just need to refer to the name of this at least here. 126 00:07:54,220 --> 00:07:59,410 Animals come on and are the list of ideas. 127 00:07:59,410 --> 00:07:59,880 OK. 128 00:08:00,100 --> 00:08:06,400 So here we need to comment out this line of code here because we don't want to actually execute these 129 00:08:06,400 --> 00:08:07,620 lines of code twice. 130 00:08:07,690 --> 00:08:08,430 OK. 131 00:08:08,770 --> 00:08:13,720 And in that way if you actually execute this line this line of code here and then execute this line 132 00:08:13,720 --> 00:08:20,020 of code here it's going to actually output those values those of animals names are to screen twice. 133 00:08:20,020 --> 00:08:23,080 So now let's actually run our project and see what happens. 134 00:08:23,110 --> 00:08:28,870 So here as you can see and here we can see that these values are outputted through the screen twice. 135 00:08:29,020 --> 00:08:29,470 OK. 136 00:08:29,500 --> 00:08:33,280 Here you can see these values twice here and now. 137 00:08:33,340 --> 00:08:38,680 Let's actually comment out of this line of code here and now it's actually not a project. 138 00:08:38,680 --> 00:08:40,980 Again let's see what happens. 139 00:08:40,990 --> 00:08:47,770 And here as you can see we can see these values here and now we can see this of Woelfel value is at 140 00:08:47,860 --> 00:08:52,330 index zero all of these are the OK of these animals. 141 00:08:52,420 --> 00:08:53,240 OK. 142 00:08:53,770 --> 00:08:55,370 So hopefully that makes sense. 143 00:08:55,390 --> 00:08:58,500 And now there's actually some more lines of code here. 144 00:08:58,510 --> 00:09:02,830 So now I want to actually remove the value that is inside of the index number. 145 00:09:02,830 --> 00:09:04,660 Two of these Adye. 146 00:09:04,810 --> 00:09:05,260 OK. 147 00:09:05,410 --> 00:09:10,240 So as you can see here this is not index number zero index number one. 148 00:09:10,390 --> 00:09:12,190 And it is index number two tiger. 149 00:09:12,220 --> 00:09:12,760 OK. 150 00:09:12,910 --> 00:09:16,040 So here I could just typing animal start. 151 00:09:16,070 --> 00:09:18,420 Remove index number two. 152 00:09:18,800 --> 00:09:19,310 OK. 153 00:09:19,390 --> 00:09:21,590 The value that is inside of the index number two. 154 00:09:21,850 --> 00:09:24,270 So here I could just take out foods. 155 00:09:24,460 --> 00:09:29,160 He out with the at least values to these to the screen by using enhanced for loop. 156 00:09:29,230 --> 00:09:34,060 And here I need to comment out this line of code here and here inside of the prentices I just need to 157 00:09:34,060 --> 00:09:40,590 refer to the name of this are the animals come on 60 at least values. 158 00:09:40,610 --> 00:09:44,580 Ok so now let's actually on our project and see what happens. 159 00:09:44,650 --> 00:09:50,830 So now as you can see the value that is inside of the index number two of this Arey is now removed. 160 00:09:50,840 --> 00:09:53,210 OK Wolf lion Chad punter. 161 00:09:53,470 --> 00:09:55,420 And we can see that value here. 162 00:09:55,510 --> 00:09:56,220 OK. 163 00:09:56,560 --> 00:09:58,400 So hopefully that makes sense. 164 00:09:58,780 --> 00:10:03,040 And now it's actually to go back inside these main activity that of a fight here.
