1 00:00:00,330 --> 00:00:07,260 I want to actually arrange the values that are inside of this tree in an ascending order. 2 00:00:07,260 --> 00:00:07,830 OK. 3 00:00:08,040 --> 00:00:12,780 So in order to do that I'm going to actually putting some lines of code here and then I explain to you 4 00:00:12,780 --> 00:00:13,750 what's going on here. 5 00:00:13,770 --> 00:00:14,520 OK. 6 00:00:14,880 --> 00:00:21,060 So as you can see here these are the lines of code that are actually posted here that are actually pasted 7 00:00:21,060 --> 00:00:25,850 here as you can see and in line 51 as you can see. 8 00:00:25,890 --> 00:00:28,600 You referred to the name of this artist class. 9 00:00:28,820 --> 00:00:29,330 OK. 10 00:00:29,490 --> 00:00:34,050 We have a predefined class in Java arrays dot sort. 11 00:00:34,050 --> 00:00:36,990 So as you can see here this is actually a class of Meffert. 12 00:00:37,020 --> 00:00:42,740 OK we call this method and these are base class arrays that sort of double values Ali. 13 00:00:42,780 --> 00:00:49,800 So this is going to actually arrange the values that are inside of these double values array in an ascending 14 00:00:49,830 --> 00:00:50,330 order. 15 00:00:50,400 --> 00:00:51,140 OK. 16 00:00:51,510 --> 00:00:58,770 And in line 42 I created an object from this string class as you can see I only declare this object 17 00:00:58,770 --> 00:00:59,290 here. 18 00:00:59,430 --> 00:01:00,600 OK this variable. 19 00:01:00,990 --> 00:01:03,220 And then I created a full loop here. 20 00:01:03,240 --> 00:01:09,930 So inside Apprentice's of this foldback you can see first of all I created a variable of type integer 21 00:01:10,440 --> 00:01:13,980 index and then I assign the value 0 to this variable. 22 00:01:14,190 --> 00:01:19,290 And then he had actually created a condition which determines how many times this group is going to 23 00:01:19,290 --> 00:01:20,520 be executed. 24 00:01:20,520 --> 00:01:27,000 So until the value of this index variable is less than the value of the length of these double values 25 00:01:27,060 --> 00:01:27,750 array. 26 00:01:28,080 --> 00:01:29,690 This loop is going to be executed. 27 00:01:29,730 --> 00:01:30,320 OK. 28 00:01:30,660 --> 00:01:38,130 And here I specified that after each execution of this for a loop increment the value of these are inexplicable 29 00:01:38,130 --> 00:01:38,780 by 1. 30 00:01:38,790 --> 00:01:39,540 OK. 31 00:01:39,840 --> 00:01:46,620 So here as you can see inside of this for loop I actually instantiated this variable all the x the R.W. 32 00:01:46,620 --> 00:01:48,310 values assignment operator. 33 00:01:48,720 --> 00:01:51,880 And here I actually referred to the name of this takes you here. 34 00:01:52,050 --> 00:01:58,230 This object takes the arrow double right to use dot gettext and getting the takes of these takes few 35 00:01:58,480 --> 00:01:59,610 thought was strange. 36 00:01:59,700 --> 00:02:04,380 And here I am converting that text to actually a string value. 37 00:02:04,380 --> 00:02:05,220 OK. 38 00:02:05,670 --> 00:02:12,620 And then here I actually assign that my data is all the x the R.W. values and then in line our first 39 00:02:12,660 --> 00:02:20,000 T5 again I actually referred to the name of this XTi a values that said text. 40 00:02:20,040 --> 00:02:26,460 I actually want to set some text to this text view all the tradable values here. 41 00:02:26,490 --> 00:02:31,480 I referred to the name of this variable so that the user can see the previous values. 42 00:02:31,520 --> 00:02:32,090 OK. 43 00:02:32,310 --> 00:02:38,920 Plus here I want to concatenate the value of this value here double values agree here. 44 00:02:38,940 --> 00:02:42,020 I referred to the name of this are a sub index. 45 00:02:42,240 --> 00:02:42,930 OK. 46 00:02:42,930 --> 00:02:49,110 So for example for the first time that this loop is going to be executed executed are the value of this 47 00:02:49,110 --> 00:02:50,580 index variable is 0. 48 00:02:50,640 --> 00:02:51,020 OK. 49 00:02:51,150 --> 00:02:52,640 So double values or index. 50 00:02:52,770 --> 00:02:54,200 Is this value OK. 51 00:02:54,300 --> 00:02:57,810 We're going to give me this 6.3 here to me. 52 00:02:57,810 --> 00:02:58,740 OK. 53 00:02:58,860 --> 00:03:07,110 And here again I actually put it I actually put up plus operator here and here I actually put a space 54 00:03:07,110 --> 00:03:09,490 here OK between the values. 55 00:03:09,510 --> 00:03:13,430 So now let's actually run our project and to see what happens. 56 00:03:13,890 --> 00:03:14,500 OK. 57 00:03:14,670 --> 00:03:21,600 Now as you can see our application is running on this emulator here and here and as you can see the 58 00:03:21,600 --> 00:03:29,170 values that are inside of these double values a here are now actually arranged in an ascending order. 59 00:03:29,170 --> 00:03:29,620 OK. 60 00:03:29,700 --> 00:03:35,040 So you can see these values in some of these scroll you hear if they actually scroll to the left here 61 00:03:35,340 --> 00:03:37,270 I can see the other values. 62 00:03:37,290 --> 00:03:38,450 OK. 63 00:03:38,460 --> 00:03:40,210 So hopefully that makes sense. 64 00:03:40,410 --> 00:03:46,850 Let's actually go back inside this main activity that job off fight here again and after this for loop 65 00:03:46,860 --> 00:03:53,010 here after the ending curly brace of this for loop that's actually putting some lines of code here. 66 00:03:53,100 --> 00:03:58,890 So now I want to actually paste in some lines of code here and then I'll explain to you what's going 67 00:03:58,890 --> 00:03:59,290 on here. 68 00:03:59,310 --> 00:04:00,110 OK. 69 00:04:00,480 --> 00:04:05,070 So as you can see here these are the two lines of code here that they actually paste that here. 70 00:04:05,070 --> 00:04:11,630 First of all in line 49 I actually created an average of integer numbers here as against. 71 00:04:12,120 --> 00:04:15,350 And the name of my great ease and numbers a. 72 00:04:15,780 --> 00:04:20,380 And then here I instantiated this at a by using this new keyboard. 73 00:04:20,550 --> 00:04:25,160 And here you specify the size of my area or the length of my addy. 74 00:04:25,440 --> 00:04:32,860 And then in line 40 I actually again referred to the name of this race class dads feel here. 75 00:04:32,870 --> 00:04:37,230 I want to actually assign some values to my arii. 76 00:04:37,290 --> 00:04:37,670 OK. 77 00:04:37,710 --> 00:04:39,030 I raise that field. 78 00:04:39,030 --> 00:04:44,010 First of all I referred to the name of this R.A. here into numbers are a comma. 79 00:04:44,370 --> 00:04:49,300 And here I specified the value that way that I want to actually assign to this Adoree. 80 00:04:49,360 --> 00:04:53,860 OK so now let's actually create Smurfette OK. 81 00:04:53,880 --> 00:04:56,290 Inside of this main activity class. 82 00:04:56,310 --> 00:05:02,940 Ok so after the ending curly brace of these uncreate Meffert as you can see it let's actually create 83 00:05:03,000 --> 00:05:04,100 another method here. 84 00:05:04,200 --> 00:05:04,890 OK. 85 00:05:05,160 --> 00:05:07,490 As you can see this is my effort here. 86 00:05:07,980 --> 00:05:14,870 And then the access modifier of mame if it is public the return type of this Meffert is void. 87 00:05:14,880 --> 00:05:17,290 So this is going to actually return nothing. 88 00:05:17,400 --> 00:05:24,060 OK the name of this method is output the arrow to the screen and this buffer is going to actually accept 89 00:05:24,060 --> 00:05:24,990 two arguments. 90 00:05:25,020 --> 00:05:29,280 OK so the first argument is actually of type integer array. 91 00:05:29,430 --> 00:05:35,940 As you can see here and the name of this argument is Aure and the second argument is actually of type 92 00:05:36,180 --> 00:05:37,290 text view. 93 00:05:37,500 --> 00:05:39,900 And the name of this argument is takes three. 94 00:05:39,900 --> 00:05:41,040 OK. 95 00:05:41,040 --> 00:05:49,540 So inside of this Meffert as you can see here in line 14:9 I actually created a string variable. 96 00:05:49,560 --> 00:05:58,700 I declared this string variable in line with the here and then I didn't instantiate this variable here. 97 00:05:58,980 --> 00:06:00,310 And here I created. 98 00:06:00,350 --> 00:06:02,010 Oh and enhanced for loop. 99 00:06:02,010 --> 00:06:02,590 OK. 100 00:06:02,910 --> 00:06:08,880 So I want to actually either rate over the values that are inside this array here inside of this integer 101 00:06:08,940 --> 00:06:09,470 array. 102 00:06:09,610 --> 00:06:16,140 OK so I created an integer of argument here number and it's going to iterate over the values that are 103 00:06:16,150 --> 00:06:17,280 inside of these aurea. 104 00:06:17,280 --> 00:06:22,470 Here we're going to actually do something with that valuable with that specific variable. 105 00:06:22,470 --> 00:06:28,940 So here I specified that I actually referred to the name of this string variable here. 106 00:06:28,950 --> 00:06:36,890 So here I actually first through the name of this text view your argument that get takes that was three. 107 00:06:36,990 --> 00:06:39,230 So here I am getting the text of this text. 108 00:06:39,270 --> 00:06:44,190 And I am converting that value to a string value and I assign that value to this. 109 00:06:44,190 --> 00:06:45,000 All it takes. 110 00:06:45,000 --> 00:06:46,050 View of value here. 111 00:06:46,050 --> 00:06:46,720 OK. 112 00:06:47,070 --> 00:06:53,800 And then in line 54 are you referring to the name of this argument takes view that set text. 113 00:06:54,000 --> 00:06:59,360 And then I actually refer to the name of this variable or it takes a value plus number. 114 00:06:59,590 --> 00:07:00,690 OK this is the number. 115 00:07:00,690 --> 00:07:03,390 This is the value that is actually inside of this Arai. 116 00:07:03,510 --> 00:07:03,820 OK. 117 00:07:03,840 --> 00:07:05,540 Plus a space here. 118 00:07:05,670 --> 00:07:06,580 OK. 119 00:07:06,980 --> 00:07:09,680 And now let's actually call this method here. 120 00:07:09,690 --> 00:07:13,540 Inside of this uncreate Meffert out foods the tray to the screen. 121 00:07:13,560 --> 00:07:14,210 OK. 122 00:07:14,370 --> 00:07:18,410 So as you can see if it actually accepts two arguments. 123 00:07:18,510 --> 00:07:22,100 So the first argument is actually of type integer array. 124 00:07:22,170 --> 00:07:27,980 So if you have an integer are a here int numbers every comma. 125 00:07:28,590 --> 00:07:31,380 And the second argument is after it takes you. 126 00:07:31,440 --> 00:07:34,200 So again just typing Tia XTi. 127 00:07:34,800 --> 00:07:38,150 And here I can just refer to the name of this object. 128 00:07:38,340 --> 00:07:40,580 The end numbers are a. 129 00:07:41,190 --> 00:07:44,750 And now let's actually run our project and see what happens. 130 00:07:44,780 --> 00:07:45,860 OK OK. 131 00:07:46,110 --> 00:07:52,710 Now as you can see our application is running on this emulator and here as you can see it says this 132 00:07:52,710 --> 00:07:56,070 is an array of integer numbers and we can see these values here. 133 00:07:56,080 --> 00:07:58,130 OK this number wants here. 134 00:07:58,230 --> 00:07:58,840 OK. 135 00:07:59,040 --> 00:08:06,090 So here we specified that we want to actually these are a this and its numbers are a bit number one 136 00:08:06,150 --> 00:08:06,400 here. 137 00:08:06,420 --> 00:08:06,890 OK. 138 00:08:06,930 --> 00:08:13,960 So as you can see this Aure actually accepts to any integer numbers of k the size of this area is 20. 139 00:08:14,160 --> 00:08:17,750 And here as you can see we can see these number ones here. 140 00:08:17,810 --> 00:08:18,050 OK. 141 00:08:18,060 --> 00:08:19,270 Inside of this arii. 142 00:08:19,380 --> 00:08:19,940 OK. 143 00:08:20,400 --> 00:08:22,750 So hopefully that makes sense. 144 00:08:22,770 --> 00:08:28,050 And let's actually go back and say this main activity that double fight here and now it's actually at 145 00:08:28,260 --> 00:08:29,630 some other courts here. 146 00:08:29,730 --> 00:08:31,910 OK inside these uncreate Smurfette. 147 00:08:31,950 --> 00:08:38,310 So now I'm going to actually pasting some lines of code here and then I'll explain to you what's going 148 00:08:38,310 --> 00:08:38,850 on here. 149 00:08:38,850 --> 00:08:39,580 OK. 150 00:08:39,990 --> 00:08:43,920 So as you can see here these are the lines of code that are actually pasted here. 151 00:08:43,980 --> 00:08:44,620 OK. 152 00:08:44,880 --> 00:08:51,410 So first of all in line 45 I created an integer array called integer a 1. 153 00:08:51,450 --> 00:08:51,950 OK. 154 00:08:52,050 --> 00:08:59,190 And here as you can see I insensate it this way by assigning these values as you can see inside of these 155 00:08:59,190 --> 00:09:03,620 curly braces these values to this integer add a 1 here. 156 00:09:03,690 --> 00:09:04,660 OK. 157 00:09:05,160 --> 00:09:11,530 And here in line 46 I actually created another array here called integer. 158 00:09:11,550 --> 00:09:12,790 Ali 1 copy. 159 00:09:12,900 --> 00:09:13,840 OK. 160 00:09:13,860 --> 00:09:20,520 And then I actually instantiated dicere by using this new keyboard here and here as you can see inside 161 00:09:20,520 --> 00:09:26,310 of the brackets here are actually specified the length of these integers are a copy here. 162 00:09:26,520 --> 00:09:33,040 So the length of these integers are a copy here is the length of this integer at a 1 here. 163 00:09:33,050 --> 00:09:35,980 OK the size of this integer at a point here. 164 00:09:36,060 --> 00:09:36,990 OK. 165 00:09:37,500 --> 00:09:42,810 And then in line 48 I actually created another line of code here.
