1 00:00:00,550 --> 00:00:03,840 And actually Harvard are mouse pointer over the area. 2 00:00:04,050 --> 00:00:05,400 So as you can see here wrong. 3 00:00:05,460 --> 00:00:09,710 Second argument type found in require Java lang that string. 4 00:00:09,720 --> 00:00:12,140 So we need to actually putting a string value. 5 00:00:12,300 --> 00:00:17,130 So in order to convert this integer value to a string value I just need to type in. 6 00:00:17,130 --> 00:00:23,670 I just need to put in a plus operator here and then I need to put into double quotes if I actually run 7 00:00:23,670 --> 00:00:24,720 my project. 8 00:00:24,750 --> 00:00:25,930 Let's see what happens. 9 00:00:25,980 --> 00:00:27,090 OK everyone. 10 00:00:27,090 --> 00:00:31,350 Now as you can see our application is actually running on this emulator. 11 00:00:31,350 --> 00:00:31,980 OK. 12 00:00:32,400 --> 00:00:36,180 So here first of all I need to actually click on this. 13 00:00:36,210 --> 00:00:40,170 Start the loop button here in order to execute these lines of code. 14 00:00:40,160 --> 00:00:42,250 Here is this for loop here. 15 00:00:42,270 --> 00:00:42,820 OK. 16 00:00:43,020 --> 00:00:48,570 So as you can see here this for loop is inside of the stack like listener Meffert that is related to 17 00:00:48,570 --> 00:00:50,060 the Spithead loop button. 18 00:00:50,070 --> 00:00:50,640 OK. 19 00:00:50,940 --> 00:00:55,920 So I just need to click on this start button here and let's see what happens. 20 00:00:56,010 --> 00:00:58,050 So as you can see here I clicked this button. 21 00:00:58,170 --> 00:00:58,720 OK. 22 00:00:58,920 --> 00:01:00,980 Now as you can see here this is our luck. 23 00:01:01,170 --> 00:01:01,800 OK. 24 00:01:02,130 --> 00:01:04,880 So here as you can see there is a log level here. 25 00:01:05,100 --> 00:01:08,800 So just click on this here and then choose info. 26 00:01:09,210 --> 00:01:14,830 So as you can see here this I hear this a lot that this stands for info. 27 00:01:15,030 --> 00:01:15,740 OK. 28 00:01:16,020 --> 00:01:19,180 So that's why we actually typed in a large dot. 29 00:01:19,550 --> 00:01:20,110 OK. 30 00:01:20,370 --> 00:01:30,210 And now here instead of disserved just type it here l o g here as you can see with the uppercase letters. 31 00:01:30,210 --> 00:01:39,880 So as you can see here these are the values that are outputted here which is 0 1 2 3 and 29. 32 00:01:40,250 --> 00:01:40,900 OK. 33 00:01:41,250 --> 00:01:45,530 So here we specified that the that the initial value is zero. 34 00:01:45,550 --> 00:01:47,920 So now let me ask you to make this area bigger. 35 00:01:48,150 --> 00:01:53,790 So here you are as you can see if you specified that the initial value is 0. 36 00:01:53,790 --> 00:01:54,340 OK. 37 00:01:54,390 --> 00:01:56,190 X 0. 38 00:01:56,220 --> 00:01:58,160 So this is our initial value. 39 00:01:58,680 --> 00:02:03,700 And here we specified that the X is less than 50. 40 00:02:04,290 --> 00:02:12,060 So it can actually execute for the for loop 13 times or 0 1 to 29. 41 00:02:12,060 --> 00:02:12,550 OK. 42 00:02:12,690 --> 00:02:20,040 As you can see here the initial value is 0 and we specified that this loop is going to be executed until 43 00:02:20,040 --> 00:02:21,830 the xx is less than 50. 44 00:02:21,900 --> 00:02:27,150 So as you can see here number two in nine we're going to actually add one value to the value of the 45 00:02:27,150 --> 00:02:30,480 Axworthy a bell every time this loop is executed. 46 00:02:30,480 --> 00:02:30,880 OK. 47 00:02:30,930 --> 00:02:33,420 As you can see numbers 0 to number 29. 48 00:02:33,420 --> 00:02:35,600 Now I want to talk about the break statement. 49 00:02:35,610 --> 00:02:36,190 OK. 50 00:02:36,450 --> 00:02:42,780 So inside this main activity that you have a file and inside of this for loop I want to actually use 51 00:02:43,530 --> 00:02:44,590 an if statement here. 52 00:02:44,590 --> 00:02:44,850 OK. 53 00:02:44,890 --> 00:02:51,630 If and that inside the prentices I can just type in x is equal to number. 54 00:02:51,630 --> 00:02:53,090 For example 10. 55 00:02:53,880 --> 00:02:58,330 And then I actually open and close my statement by using these curly braces. 56 00:02:58,380 --> 00:03:00,380 I can just type in break. 57 00:03:01,970 --> 00:03:02,680 OK. 58 00:03:03,100 --> 00:03:07,980 So now let's actually let our project and see what happens. 59 00:03:08,050 --> 00:03:13,480 As you can see here we've got these start the loop pattern here OK so we need to click this button in 60 00:03:13,480 --> 00:03:16,410 order to execute this for loop here OK. 61 00:03:16,510 --> 00:03:18,850 So start the loop ok everyone. 62 00:03:18,910 --> 00:03:23,460 Now as you can see our application is actually running on this emulator here. 63 00:03:23,500 --> 00:03:30,430 And then let's actually click on this start button here because we need to actually click this button 64 00:03:30,790 --> 00:03:32,840 in order to execute this for loop here. 65 00:03:32,860 --> 00:03:33,540 OK. 66 00:03:33,970 --> 00:03:36,600 So I can just click this button here. 67 00:03:37,060 --> 00:03:41,780 And as you can see here now it can actually execute this for loop here. 68 00:03:41,800 --> 00:03:42,320 OK. 69 00:03:42,520 --> 00:03:47,990 So as you can see here we've got some informations that are actually related to the old cats. 70 00:03:48,130 --> 00:03:48,540 OK. 71 00:03:48,580 --> 00:03:55,750 So in order to actually delete these locks we need to actually click these are this clear locked Chad 72 00:03:55,750 --> 00:03:56,030 here. 73 00:03:56,050 --> 00:03:56,440 OK. 74 00:03:56,500 --> 00:03:57,740 OK it is clear. 75 00:03:57,750 --> 00:03:58,810 Look Chad here. 76 00:03:58,990 --> 00:04:03,910 OK so just click on this a clear cut as you can see now the lock Chad is empty. 77 00:04:03,910 --> 00:04:04,800 OK. 78 00:04:04,930 --> 00:04:06,170 So again click on this. 79 00:04:06,190 --> 00:04:07,670 Start the loop here. 80 00:04:08,260 --> 00:04:10,360 And now these are the new information. 81 00:04:10,540 --> 00:04:11,060 OK. 82 00:04:11,320 --> 00:04:18,640 So as you can see here first of all let me point out that we created a full loop here OK for int x is 83 00:04:18,640 --> 00:04:19,700 equal to zero. 84 00:04:19,870 --> 00:04:23,350 X is less than a 30 x plus plus. 85 00:04:23,470 --> 00:04:24,080 OK. 86 00:04:24,310 --> 00:04:30,920 And then inside the for loop I specified that if x is equal to number 10 and break. 87 00:04:31,000 --> 00:04:31,570 OK. 88 00:04:31,600 --> 00:04:33,260 And that in line 65. 89 00:04:33,490 --> 00:04:39,350 I actually decided to output these are values the value of the X valuable to the lock. 90 00:04:39,630 --> 00:04:39,990 OK. 91 00:04:40,030 --> 00:04:41,760 So let's see what is happening here. 92 00:04:41,800 --> 00:04:49,420 0 1 2 3 4 5 6 7 8 9. 93 00:04:49,570 --> 00:04:53,680 As you can see here of when it actually reaches this not the number 9. 94 00:04:53,740 --> 00:04:56,310 It is actually breaking out of this for loop here. 95 00:04:56,440 --> 00:04:59,870 And it is not going to actually execute this for loop anymore. 96 00:05:00,010 --> 00:05:01,860 So that's the job of play. 97 00:05:02,080 --> 00:05:05,670 It is going to actually break out of that a for loop. 98 00:05:05,680 --> 00:05:06,290 OK. 99 00:05:06,340 --> 00:05:07,880 So hopefully that makes sense. 100 00:05:08,140 --> 00:05:12,740 And now I want to actually create an example about it to continue. 101 00:05:13,000 --> 00:05:17,520 So let's actually comment out these lines of code here. 102 00:05:18,740 --> 00:05:27,150 And now let's actually again create up an if statement if and that inside the prentices I can just type 103 00:05:27,150 --> 00:05:30,630 in x is equal to number. 104 00:05:30,640 --> 00:05:37,900 For example 5 and then I need to actually open and close my statement by using this curly braces. 105 00:05:38,050 --> 00:05:43,710 And then inside the curly braces I can just typing continue. 106 00:05:43,720 --> 00:05:46,710 So let's actually run our project and see what happens. 107 00:05:46,840 --> 00:05:47,730 OK everyone. 108 00:05:47,770 --> 00:05:52,190 Now as you can see our application is actually running on this emulator here. 109 00:05:52,270 --> 00:05:52,870 OK. 110 00:05:53,140 --> 00:05:59,050 So first let's actually so first of all let's actually deleted these logs here. 111 00:05:59,380 --> 00:05:59,990 OK. 112 00:06:00,010 --> 00:06:01,220 These are the old lugs. 113 00:06:01,300 --> 00:06:02,750 So we don't need them here. 114 00:06:02,800 --> 00:06:07,040 So just click on this are clear like that here. 115 00:06:07,390 --> 00:06:14,450 And let's actually click this Tarth the loop button here and now as you can see these are the new information. 116 00:06:14,560 --> 00:06:14,970 OK. 117 00:06:15,070 --> 00:06:21,550 So 0 1 2 3 4 6 as you can see. 118 00:06:21,640 --> 00:06:23,670 We cannot see number five here. 119 00:06:23,710 --> 00:06:23,980 OK. 120 00:06:23,980 --> 00:06:27,450 It didn't actually execute this line of code here. 121 00:06:27,490 --> 00:06:29,740 When it reaches number five. 122 00:06:30,150 --> 00:06:33,700 OK this for loop is going to be executed 30 times. 123 00:06:33,700 --> 00:06:40,270 It can actually start with the number 0 1 2 and 2 number 29 which is going to be 50 times that this 124 00:06:40,270 --> 00:06:41,990 loop is going to be executed. 125 00:06:42,250 --> 00:06:42,720 OK. 126 00:06:42,790 --> 00:06:47,760 But when it reaches the number five it is not going to execute this line of code. 127 00:06:47,790 --> 00:06:49,090 It is not going to execute. 128 00:06:49,150 --> 00:06:53,610 Are other lines of code after this statement here. 129 00:06:53,620 --> 00:06:54,220 OK. 130 00:06:54,310 --> 00:07:00,040 And this means and this means it's going to to go again inside of this for loop and add one value to 131 00:07:00,040 --> 00:07:01,570 the value of the variable. 132 00:07:01,600 --> 00:07:05,610 So when it reaches the number five it is not going to actually execute other lines of code. 133 00:07:05,620 --> 00:07:11,860 After this if statement and it's going I should add one value to the value of the x variable and then 134 00:07:11,860 --> 00:07:13,860 it's going to actually be number 6. 135 00:07:13,870 --> 00:07:17,500 So as you can see here this is number 6 and 7 and so on. 136 00:07:17,860 --> 00:07:18,580 OK. 137 00:07:18,940 --> 00:07:21,020 So hopefully that makes sense. 138 00:07:21,250 --> 00:07:24,370 And I think that's enough for this tutorial. 139 00:07:24,490 --> 00:07:29,950 And if you have any questions please post the discussion in the calls and then I'll do my best to answer 140 00:07:29,950 --> 00:07:30,860 your questions. 141 00:07:30,930 --> 00:07:35,230 And thank you very much for watching and I'll see you in the next tutorial.
