1 00:00:00,330 --> 00:00:04,620 That's because of this space between these two words OK. 2 00:00:04,740 --> 00:00:06,340 And that's the job of this. 3 00:00:06,350 --> 00:00:08,250 ESTRIN tokenizer class. 4 00:00:08,280 --> 00:00:11,420 OK so now let me actually show you another example. 5 00:00:11,670 --> 00:00:12,200 OK. 6 00:00:12,300 --> 00:00:16,180 Now let me actually comment out these lines of code here. 7 00:00:16,260 --> 00:00:19,780 Now I want to actually create another string object. 8 00:00:19,830 --> 00:00:25,770 So first I need to refer to the name of the String class and then I need to give a name to this object. 9 00:00:25,770 --> 00:00:27,860 For example Esti are two. 10 00:00:28,110 --> 00:00:33,930 And then I need to put in an assignment operator here and then I put into double quotes here and then 11 00:00:33,960 --> 00:00:37,550 inside it double codes I can actually assign some values to this object. 12 00:00:37,560 --> 00:00:40,670 OK this is another text at site. 13 00:00:40,680 --> 00:00:46,000 This is your text at sign. 14 00:00:46,050 --> 00:00:51,860 This is my text and then I need to put in a semi-colon at the end of my statement. 15 00:00:52,080 --> 00:00:52,810 OK. 16 00:00:53,490 --> 00:00:59,230 So now I can actually create another as 3 and tokenizer object. 17 00:00:59,250 --> 00:00:59,960 OK. 18 00:01:00,000 --> 00:01:05,760 So first I need to refer to the name of this string tokenizer class and then I need to give a name to 19 00:01:05,760 --> 00:01:06,510 this object. 20 00:01:06,510 --> 00:01:08,740 For example as the odd object. 21 00:01:09,000 --> 00:01:15,690 And then I need to put in an assignment operator here and then I need to actually putting this key word 22 00:01:15,690 --> 00:01:17,170 here new. 23 00:01:17,670 --> 00:01:21,270 And then again I need to refer to the name of this three tokenizer class. 24 00:01:21,410 --> 00:01:22,100 OK. 25 00:01:22,140 --> 00:01:26,030 And then again I need to the first with the name of this drink tokenizer class. 26 00:01:26,040 --> 00:01:26,550 OK. 27 00:01:26,640 --> 00:01:30,790 So first of all I want to refer to the name of this as we are to object. 28 00:01:30,870 --> 00:01:31,650 OK. 29 00:01:32,220 --> 00:01:39,160 And then I put in a comma here and then I put two double quotes here and then inside double quotes are 30 00:01:39,160 --> 00:01:43,710 you just putting this character here at side OK. 31 00:01:43,860 --> 00:01:46,860 And then I need to put in a semi-colon at the end of my statement. 32 00:01:47,070 --> 00:01:54,060 So now I want to actually set some texts to these two this takes the one object. 33 00:01:54,060 --> 00:01:54,530 OK. 34 00:01:54,780 --> 00:02:02,160 So first I need to refer to the name of this object the one that said text and then I need to refer 35 00:02:02,160 --> 00:02:06,240 to the name of this object as t r object to. 36 00:02:06,480 --> 00:02:07,320 OK. 37 00:02:07,650 --> 00:02:10,490 Dot next token. 38 00:02:10,530 --> 00:02:16,590 So as you can see here now if I were on my project let's see what happens when I try to run a project 39 00:02:17,040 --> 00:02:18,800 on this simulator here. 40 00:02:19,020 --> 00:02:23,380 So as you can see here it says this is another text. 41 00:02:23,460 --> 00:02:26,590 Ok so this is our RTX the one object. 42 00:02:26,610 --> 00:02:29,150 OK this is another text. 43 00:02:29,400 --> 00:02:32,230 So what's going on here as you can see here. 44 00:02:32,250 --> 00:02:33,780 I put this text here. 45 00:02:33,900 --> 00:02:34,490 OK. 46 00:02:34,710 --> 00:02:37,530 And it only showed us this text. 47 00:02:37,530 --> 00:02:39,530 This is another text here. 48 00:02:39,540 --> 00:02:45,630 I actually created a string object called Esti are two objects called Esti are two. 49 00:02:45,690 --> 00:02:53,200 And here I created an object from this three tokenizer class called Esti are object to. 50 00:02:53,400 --> 00:02:53,860 OK. 51 00:02:53,970 --> 00:02:58,930 And for this constructor I passed two values here first. 52 00:02:59,160 --> 00:03:00,310 I actually passed. 53 00:03:00,330 --> 00:03:02,560 This is the R to object. 54 00:03:02,670 --> 00:03:08,910 OK this is an object of type as 3 and I actually passed this value here inside these double quotes at 55 00:03:08,900 --> 00:03:09,540 sign. 56 00:03:09,720 --> 00:03:14,490 OK so this is going to be our daily meter for our Esti are two objects. 57 00:03:14,520 --> 00:03:15,030 OK. 58 00:03:15,030 --> 00:03:22,920 So this second argument as you can see here is at Slyne inside these double coats here indicates that 59 00:03:22,920 --> 00:03:28,450 the at sign character should be used as the delimiter between tokens. 60 00:03:28,490 --> 00:03:35,720 OK so let me actually repeat again this ad saying character here indicates that the at sign character 61 00:03:35,940 --> 00:03:39,980 should be used as the delimiter between tokens. 62 00:03:40,010 --> 00:03:41,520 Ok for example. 63 00:03:41,920 --> 00:03:42,500 OK. 64 00:03:42,690 --> 00:03:51,560 So this is here indicates that this vote here should be used as the delimiter between tokens. 65 00:03:51,750 --> 00:03:55,240 So if you are on my project now let's see what happens. 66 00:03:55,290 --> 00:04:01,990 And here as you can see it actually put this t h here as the value of these TXI the word object. 67 00:04:02,010 --> 00:04:02,720 OK. 68 00:04:02,940 --> 00:04:10,440 So as you can see here are I specified that this vort this word here should be used as the delimiter 69 00:04:10,440 --> 00:04:11,480 between characters. 70 00:04:11,490 --> 00:04:11,880 OK. 71 00:04:11,910 --> 00:04:15,470 So as you can see here this is is the delimiter between tokens. 72 00:04:15,540 --> 00:04:18,390 So it only actually outputted this. 73 00:04:18,600 --> 00:04:21,140 Th here too this takes through here. 74 00:04:21,170 --> 00:04:28,230 OK so now let me I actually changed this word here to at sign and if on my project again it's going 75 00:04:28,230 --> 00:04:30,680 to actually put this text here. 76 00:04:30,690 --> 00:04:32,240 This is another text. 77 00:04:32,250 --> 00:04:32,820 OK. 78 00:04:32,820 --> 00:04:37,160 So it's going to take Actually some time in order to actually run our project again. 79 00:04:37,170 --> 00:04:39,420 As you can see this is another text. 80 00:04:39,420 --> 00:04:45,580 Ok so now if you want to actually set some text to the text the two object. 81 00:04:45,600 --> 00:04:46,980 Let's see what happens. 82 00:04:47,020 --> 00:04:52,880 The x the two dots set text. 83 00:04:52,890 --> 00:04:58,860 As you can see here I actually used the autocomplete feature of the Android stood you by pressing on 84 00:04:58,850 --> 00:05:02,920 the control plus the space key on your keyboard. 85 00:05:02,920 --> 00:05:03,340 OK. 86 00:05:03,400 --> 00:05:07,590 And then inside the apprentices I need to refer to the name of this object. 87 00:05:07,600 --> 00:05:12,990 Esti are object to dot next token. 88 00:05:13,030 --> 00:05:15,640 So let's actually run our project and see what happens. 89 00:05:15,640 --> 00:05:20,430 So it's going to actually take some time in order to run our project as you can see. 90 00:05:20,440 --> 00:05:23,500 This is your text here as you can see here. 91 00:05:23,530 --> 00:05:27,640 So this site here is the delimiter between these characters. 92 00:05:27,640 --> 00:05:30,580 First it outputted are the stakes here. 93 00:05:30,580 --> 00:05:33,710 This is another text and then it outputted. 94 00:05:33,730 --> 00:05:34,600 This takes here. 95 00:05:34,600 --> 00:05:42,220 This is your text and if I actually put another text view inside this content underline main example 96 00:05:42,490 --> 00:05:43,570 let's see what happens. 97 00:05:43,570 --> 00:05:53,170 For example it's actually true that a large takes few here and then I need to actually assign an ID 98 00:05:53,170 --> 00:05:54,750 to these text view. 99 00:05:54,850 --> 00:05:58,600 For example the free t XTi free. 100 00:05:59,350 --> 00:06:05,710 And then inside the main activity that Java as you can see here now I can actually create an object 101 00:06:06,040 --> 00:06:11,380 from this text view class and that night and then I can refer to that takes the free object here. 102 00:06:11,380 --> 00:06:11,840 OK. 103 00:06:11,890 --> 00:06:17,430 So first I need to refer to the name of the text to your class and then I need to give a name to this 104 00:06:17,970 --> 00:06:18,520 object. 105 00:06:18,550 --> 00:06:20,520 TSTO XTi Freep. 106 00:06:20,530 --> 00:06:28,120 And then I need to put in an assignment operator here and then inside Apprentice's I can actually refer 107 00:06:28,120 --> 00:06:31,330 to the name of the text class text view. 108 00:06:31,600 --> 00:06:32,370 OK. 109 00:06:32,860 --> 00:06:42,990 And then I need to type in here find view by ID or that Id Dot T XTi free. 110 00:06:43,470 --> 00:06:44,110 OK. 111 00:06:44,380 --> 00:06:47,820 And then I need to put in a semi-colon at the end of my statement. 112 00:06:47,990 --> 00:06:54,430 OK so here I can assign a value to that to the free object DXi free. 113 00:06:54,460 --> 00:06:57,160 That said text. 114 00:06:58,300 --> 00:07:00,280 As you can see here this set text. 115 00:07:00,280 --> 00:07:03,800 Here is an instance Smurfette from this text through class. 116 00:07:03,820 --> 00:07:04,280 OK. 117 00:07:04,360 --> 00:07:06,420 So the free that said text. 118 00:07:06,640 --> 00:07:14,080 And then inside Apprentice's I can't just refer to the name of this Esti are object to dot next token. 119 00:07:14,450 --> 00:07:15,130 OK. 120 00:07:15,310 --> 00:07:21,940 So as you can see here this next token method here is again an instance Smurfette from this is tokenizer 121 00:07:21,940 --> 00:07:22,320 class. 122 00:07:22,350 --> 00:07:23,370 OK OK. 123 00:07:23,410 --> 00:07:24,950 So now if I run my project. 124 00:07:24,970 --> 00:07:26,290 So as you can see here. 125 00:07:26,500 --> 00:07:31,030 So as you can see said this is another text and this is disvalue is here. 126 00:07:31,030 --> 00:07:32,600 This is your text. 127 00:07:32,860 --> 00:07:35,960 This value is here and this is my text. 128 00:07:36,010 --> 00:07:36,340 OK. 129 00:07:36,340 --> 00:07:38,190 And this is disvalue is here. 130 00:07:38,230 --> 00:07:39,090 OK. 131 00:07:39,520 --> 00:07:41,390 So hopefully that makes sense. 132 00:07:41,440 --> 00:07:46,040 I can't even concatenate this value here with another value. 133 00:07:46,210 --> 00:07:48,640 I just need to put in the plus operator here. 134 00:07:48,970 --> 00:07:54,570 And then I can put it into double quotes and then inside the double cords I can put in another text 135 00:07:54,580 --> 00:07:56,700 for example fine. 136 00:07:57,390 --> 00:08:01,430 OK so now if I had on my project let's see what happens. 137 00:08:01,630 --> 00:08:06,570 OK it's going to take some time in order to run our project as you can see here. 138 00:08:06,790 --> 00:08:10,630 It puts this fine work here at the end of this text here. 139 00:08:10,630 --> 00:08:11,300 OK. 140 00:08:11,740 --> 00:08:13,130 This is my text. 141 00:08:13,270 --> 00:08:14,270 OK. 142 00:08:14,990 --> 00:08:21,090 I can actually put in a space here in order to make this value more readable. 143 00:08:21,790 --> 00:08:25,240 And if I run my project again it's going to actually run our project. 144 00:08:25,390 --> 00:08:28,270 It's going to take some time in order to run a project. 145 00:08:28,270 --> 00:08:32,760 So as you can see here it put this space here before is fine. 146 00:08:32,770 --> 00:08:33,830 Vote here OK. 147 00:08:34,000 --> 00:08:35,620 So this is my test flight. 148 00:08:35,710 --> 00:08:39,700 So first let me actually talk a little bit about constructors. 149 00:08:39,700 --> 00:08:40,410 OK. 150 00:08:40,750 --> 00:08:47,260 In the previous tutorials I talked about constructors and how and how we can actually create our own 151 00:08:47,570 --> 00:08:48,690 constructors. 152 00:08:49,000 --> 00:08:55,930 But here let me actually point out that several things happen when you use the new operator here. 153 00:08:56,010 --> 00:08:56,350 OK. 154 00:08:56,350 --> 00:09:02,530 For example when you are creating an object from this string Thring tokenizer class several things happen. 155 00:09:02,590 --> 00:09:03,350 OK. 156 00:09:03,370 --> 00:09:12,470 When we actually use this new keyboard here OK the new instance of the given class is created OK. 157 00:09:12,970 --> 00:09:15,000 Memory is allocated for it. 158 00:09:15,160 --> 00:09:22,010 And our special method defined in the given class is called and that special Meffert is constructed. 159 00:09:22,020 --> 00:09:22,750 OK. 160 00:09:23,040 --> 00:09:32,170 Our construct here is a way to create a new instance of a Class A constructor initializes the new object 161 00:09:32,740 --> 00:09:34,760 and it's valuable as OK. 162 00:09:34,780 --> 00:09:40,510 As you saw in the previous tutorials that I actually showed you how you can actually initialize your 163 00:09:40,510 --> 00:09:45,070 objects and your variables by using the constructor. 164 00:09:45,250 --> 00:09:45,930 OK. 165 00:09:46,060 --> 00:09:48,390 A constructor is actually a special method. 166 00:09:48,550 --> 00:09:51,580 A constructor cannot have a return type. 167 00:09:51,580 --> 00:09:54,830 OK but if it's nice to have a return type. 168 00:09:55,030 --> 00:09:59,490 OK that's the difference between a constructor and a method.
