1 00:00:00,480 --> 00:00:04,940 So as you can see here I have an array of arrays here. 2 00:00:05,040 --> 00:00:05,620 OK. 3 00:00:05,820 --> 00:00:12,360 So as you can see here these are these are actually the rows of my tray and these values that are actually 4 00:00:12,360 --> 00:00:15,910 inside of these arrays are the columns of this houri. 5 00:00:16,010 --> 00:00:22,950 OK so now let's actually create another array here and another two dimensional array here. 6 00:00:23,400 --> 00:00:31,370 So here it is my and other at a here as you can see again the Data Type of my Aure is integer. 7 00:00:31,470 --> 00:00:39,480 And here because I needed to actually create a two dimensional array I needed to actually put in two 8 00:00:39,480 --> 00:00:40,740 pair of brackets here. 9 00:00:40,800 --> 00:00:41,540 OK. 10 00:00:41,940 --> 00:00:45,920 And the name of this is in that area too. 11 00:00:46,020 --> 00:00:50,070 And here I actually instantiated this Arey by putting these values here. 12 00:00:50,070 --> 00:00:50,600 OK. 13 00:00:50,820 --> 00:00:55,580 So as you can see here again I have an array of alays here. 14 00:00:55,590 --> 00:00:56,330 OK. 15 00:00:56,700 --> 00:01:02,790 So again these are days as you can see here are the rows of my array and these values that are actually 16 00:01:02,790 --> 00:01:06,980 inside of this place are actually the columns of my arii. 17 00:01:07,020 --> 00:01:11,310 OK let's actually create our method here inside of this class. 18 00:01:11,460 --> 00:01:12,010 OK. 19 00:01:12,240 --> 00:01:16,080 So I just pasting this knife at here and then I'll explain what's going on here. 20 00:01:16,080 --> 00:01:16,790 OK. 21 00:01:17,190 --> 00:01:21,090 So as you can see here this is the method that they actually pasted here. 22 00:01:21,090 --> 00:01:21,680 OK. 23 00:01:21,960 --> 00:01:25,240 So the access modifier of this method is public. 24 00:01:25,500 --> 00:01:32,940 The return type of this method is void and the name of this method is let's output the ARII to the screen. 25 00:01:32,940 --> 00:01:33,470 OK. 26 00:01:33,630 --> 00:01:36,810 So this method actually accepts two arguments. 27 00:01:36,840 --> 00:01:43,920 OK so the first argument as you can see is actually a two dimensional array of type integer as you can 28 00:01:43,920 --> 00:01:44,620 see here. 29 00:01:44,910 --> 00:01:51,600 And my second argument is actually of type text view here as you can see and the name of this argument 30 00:01:51,630 --> 00:01:54,860 is takes through and inside of this method. 31 00:01:54,870 --> 00:01:59,760 First of all in line 59 I actually created a string object. 32 00:01:59,760 --> 00:02:00,910 OK. 33 00:02:01,500 --> 00:02:04,180 But I didn't actually instantiated this object yet. 34 00:02:04,200 --> 00:02:06,830 OK so I just declare this object here. 35 00:02:06,840 --> 00:02:14,080 OK this valuable all column's value and here I created a for loop as you can see here. 36 00:02:14,310 --> 00:02:15,970 This is this is my for loop. 37 00:02:16,290 --> 00:02:19,650 And inside Apprentice's of this for loop. 38 00:02:19,650 --> 00:02:27,510 First of all I actually specified that I have a variable of type integer and the name of this variable 39 00:02:27,510 --> 00:02:31,850 is the row and I assigned the value 0 to this row variable. 40 00:02:31,860 --> 00:02:32,430 OK. 41 00:02:32,700 --> 00:02:34,730 And here I created a condition. 42 00:02:34,930 --> 00:02:35,440 OK. 43 00:02:35,550 --> 00:02:43,140 So until the value of this row valuable is less than the value of the length of this integer area here 44 00:02:43,170 --> 00:02:49,170 as you can see this argument here I am referring to the name of this argument OK and it's free. 45 00:02:49,440 --> 00:02:59,250 So as long as the value of this row variable is less than the value of this length of this Aure this 46 00:02:59,250 --> 00:03:00,850 loop is going to be executed. 47 00:03:01,080 --> 00:03:01,830 OK. 48 00:03:02,490 --> 00:03:09,270 And here I am actually specifying that after each execution of this for loop as you can see here after 49 00:03:09,270 --> 00:03:15,430 each execution of this for loop or the value of this row variable is going to be incremented by 1. 50 00:03:15,570 --> 00:03:16,340 OK. 51 00:03:16,650 --> 00:03:20,600 So again inside of this loop I have an order for loop here. 52 00:03:20,850 --> 00:03:21,450 OK. 53 00:03:21,720 --> 00:03:24,860 And here inside Apprentice's of this for loop. 54 00:03:25,020 --> 00:03:32,370 First of all I created another variable as you can see here of type integer and the name of this variable 55 00:03:32,370 --> 00:03:33,720 is column. 56 00:03:33,840 --> 00:03:38,200 And here I assigned the values 0 to this column variable. 57 00:03:38,640 --> 00:03:42,330 And here I again created another condition here. 58 00:03:42,480 --> 00:03:51,070 So here I specified that until the value of this column variable is less than the value of the end. 59 00:03:51,110 --> 00:03:53,910 Ari sup wrote that line. 60 00:03:54,180 --> 00:03:54,920 OK. 61 00:03:55,200 --> 00:04:00,150 Ari Suppe wrote that line then this loop is going to be executed. 62 00:04:00,150 --> 00:04:00,670 OK. 63 00:04:00,960 --> 00:04:07,020 So it integrates abroad that means for example for the first time that this loop this loop is going 64 00:04:07,020 --> 00:04:12,060 to be executed the value of this for the value of this row variable is 0. 65 00:04:12,060 --> 00:04:16,460 OK so it's a Sub-Zero means. 66 00:04:16,680 --> 00:04:22,000 For example this Arey as if you actually work on this Ari. 67 00:04:22,150 --> 00:04:24,520 Ari one Sub-Zero means this at. 68 00:04:24,530 --> 00:04:25,040 OK. 69 00:04:25,060 --> 00:04:28,420 It's going to actually go inside of the index zero of this. 70 00:04:28,440 --> 00:04:34,380 So this rate as you can see here inside of this array is the index 0 and then it's going to give us 71 00:04:34,410 --> 00:04:39,600 actually the values that are actually inside of this array here. 72 00:04:39,660 --> 00:04:40,190 OK. 73 00:04:40,350 --> 00:04:41,690 So these are the columns. 74 00:04:41,700 --> 00:04:42,190 OK. 75 00:04:42,300 --> 00:04:47,190 And this is each of these areas are actually the rows of these. 76 00:04:47,270 --> 00:04:47,630 Right. 77 00:04:47,640 --> 00:04:48,370 OK. 78 00:04:48,840 --> 00:04:56,920 So here we specify that until the value of this column valuable is less than the value of the int array. 79 00:04:56,940 --> 00:04:58,790 Someone wrote that line. 80 00:04:59,220 --> 00:05:01,480 Then this group is it to be executed. 81 00:05:01,480 --> 00:05:08,790 And here I specified that after each execution of this for loop ok after each execution of this full 82 00:05:08,790 --> 00:05:13,470 loop the value of this column by the table is going to be incremented by 1. 83 00:05:13,570 --> 00:05:14,490 OK. 84 00:05:14,890 --> 00:05:21,550 And inside of this for loop here I actually instantiated this variable this string object as you can 85 00:05:21,550 --> 00:05:22,620 see here. 86 00:05:22,930 --> 00:05:26,990 And I actually assigned this value to this valuable text view. 87 00:05:27,010 --> 00:05:30,240 So I actually referred to the name of this argument. 88 00:05:30,350 --> 00:05:33,620 Takes few that get text that too is strange. 89 00:05:33,680 --> 00:05:39,780 Here I am converting this value to us string value and I am assigning this value to this old column's 90 00:05:39,780 --> 00:05:40,320 value. 91 00:05:40,340 --> 00:05:43,710 Ok here I am actually getting the text of the stakes. 92 00:05:43,740 --> 00:05:44,390 OK. 93 00:05:44,800 --> 00:05:47,850 And in line forty six here. 94 00:05:48,070 --> 00:05:54,250 I actually again referred to the name of this argument as you can see here takes viewed view that said 95 00:05:54,250 --> 00:05:54,940 text. 96 00:05:54,940 --> 00:05:59,170 So you want to actually set some text to this text view here. 97 00:05:59,530 --> 00:06:01,070 All Cullens value here. 98 00:06:01,100 --> 00:06:04,930 You referred to the name of this object with the name of this variable. 99 00:06:04,990 --> 00:06:05,540 OK. 100 00:06:05,680 --> 00:06:09,310 So that the user can see the previous values. 101 00:06:09,460 --> 00:06:10,100 OK. 102 00:06:10,360 --> 00:06:19,580 Plus here I want to concatenate dissuade you with the newest value into a sub row sub column. 103 00:06:19,830 --> 00:06:20,510 OK. 104 00:06:20,650 --> 00:06:28,630 And again actually putting a plus operator here in order to concatenate this value of this a dash here 105 00:06:28,630 --> 00:06:29,160 OK. 106 00:06:29,500 --> 00:06:35,290 I actually put in two double quotes and I actually put in a dash here so that so that the user can see 107 00:06:35,290 --> 00:06:36,190 the values bit. 108 00:06:36,210 --> 00:06:36,960 OK. 109 00:06:37,420 --> 00:06:45,320 And now inside of these uncreate Meffert is actually referred to the name of this effort here lets out 110 00:06:45,450 --> 00:06:47,650 with the arrow to the screen. 111 00:06:47,800 --> 00:06:51,860 So as you can see here this is going to actually accept two arguments. 112 00:06:51,880 --> 00:06:52,310 OK. 113 00:06:52,390 --> 00:06:58,090 As you can see here the first argument that this effect is going to accept as you can see is of type 114 00:06:58,120 --> 00:07:00,610 two dimensional array as you can see here. 115 00:07:00,610 --> 00:07:01,420 Integer. 116 00:07:01,690 --> 00:07:04,410 So here we have two dimensional arrays here. 117 00:07:04,750 --> 00:07:12,120 And I can just revert to the name of this in every one here and add a one so comma. 118 00:07:12,360 --> 00:07:13,210 OK. 119 00:07:13,260 --> 00:07:18,590 And now I need to actually specify the second argument which is actually of type text. 120 00:07:18,600 --> 00:07:22,300 Ok so here I can't just refer to the name of this THC. 121 00:07:22,330 --> 00:07:25,470 Everyone thinks the every one. 122 00:07:25,570 --> 00:07:26,300 OK. 123 00:07:26,830 --> 00:07:30,230 And now let's actually again the to the name of this fifth. 124 00:07:30,310 --> 00:07:36,810 Let's output the array to the screen again the first argument is of type two dimensional array of type 125 00:07:36,820 --> 00:07:38,610 integer as you can see here. 126 00:07:38,890 --> 00:07:48,620 So here again just refers to the name of this Arey ain't ready to OK comma X the end of a two. 127 00:07:48,790 --> 00:07:54,730 OK so now let's actually run our project and see what happens. 128 00:07:54,730 --> 00:07:57,900 So just click on this run button here. 129 00:07:57,910 --> 00:08:02,200 So now as you can see our application is running on this emulator. 130 00:08:02,350 --> 00:08:04,570 And here we can see these values here. 131 00:08:04,570 --> 00:08:05,080 OK. 132 00:08:05,260 --> 00:08:11,920 So for example if we actually scroll to the left here as you can see here now I can see the other values. 133 00:08:11,930 --> 00:08:17,020 Ok these values are actually inside of these in every one. 134 00:08:17,080 --> 00:08:17,690 OK. 135 00:08:17,860 --> 00:08:23,150 And here I can actually again scroll to the left and see the other values. 136 00:08:23,170 --> 00:08:28,810 Ok so now let's actually go back inside this content and the line made that example. 137 00:08:29,080 --> 00:08:31,830 And here I need to click on this clear cache. 138 00:08:32,410 --> 00:08:38,220 And here I just need to open this key componentry section here as you can see. 139 00:08:38,590 --> 00:08:43,690 I just need to open this linearly out and select this horizontal scroll view here. 140 00:08:43,840 --> 00:08:48,770 And for the layout height I can just assign the value 50. 141 00:08:49,030 --> 00:08:49,700 OK. 142 00:08:50,050 --> 00:08:56,410 And for this second horizontal here again I can assign the value of 50 for the length height. 143 00:08:56,410 --> 00:08:57,080 OK. 144 00:08:57,280 --> 00:09:01,390 So let's run our project again and see what happens. 145 00:09:01,390 --> 00:09:04,750 So here our application is running on this emulator. 146 00:09:04,840 --> 00:09:07,070 And here if we actually scroll to the left. 147 00:09:07,210 --> 00:09:09,170 And now I can see the values better. 148 00:09:09,180 --> 00:09:09,910 OK. 149 00:09:10,180 --> 00:09:15,750 So here are the values that are actually inside of these main activity that are right here. 150 00:09:15,760 --> 00:09:22,090 As you can see this is my area one and these values are actually inside of this in array one. 151 00:09:22,330 --> 00:09:27,700 And here we have this array too and these values are actually inside of that. 152 00:09:27,740 --> 00:09:28,220 OK.
