1 00:00:00,360 --> 00:00:04,270 And this is the address of this my life an object inside the memory. 2 00:00:04,290 --> 00:00:04,960 OK. 3 00:00:05,200 --> 00:00:05,760 OK. 4 00:00:05,910 --> 00:00:13,710 So now that my object is created all you want to actually access its characteristics and behaviors and 5 00:00:13,710 --> 00:00:15,740 then output them to the console. 6 00:00:15,840 --> 00:00:23,270 So now I just need to type in here sister data out that print to learn and that inside the prentices 7 00:00:23,800 --> 00:00:31,840 I just need to refer to the name of my object my lion and then I want to access its speed instance valuable. 8 00:00:32,020 --> 00:00:37,960 So I just use the dot notation here and then I choose this instance variable. 9 00:00:38,560 --> 00:00:43,690 And then at the end of my statement I need to put in a semicolon and if I get on my project. 10 00:00:43,720 --> 00:00:50,630 Now as you can see this is the value of this instance variable of this specific object. 11 00:00:50,650 --> 00:00:51,340 OK. 12 00:00:52,120 --> 00:00:56,260 So the value of this split instance variable is 90. 13 00:00:56,260 --> 00:00:56,690 OK. 14 00:00:56,710 --> 00:01:03,810 And now I want to output the value of the power instance variable of this object. 15 00:01:03,820 --> 00:01:04,280 OK. 16 00:01:04,420 --> 00:01:14,150 So here I just need to typing system that out that print learn and then inside the prentices I just 17 00:01:14,150 --> 00:01:21,530 need to refer to the name of my object and then I use the dot notation here in order to access the power 18 00:01:21,530 --> 00:01:22,570 instance variable. 19 00:01:22,590 --> 00:01:24,260 Ok power. 20 00:01:25,100 --> 00:01:30,800 And then at the end of my statement I need to put in a semi-colon and if I get on my project now this 21 00:01:30,800 --> 00:01:37,940 value is the value of the power instance variable of this specific object. 22 00:01:37,960 --> 00:01:39,450 OK my lawyer an object. 23 00:01:39,580 --> 00:01:43,460 OK so now I want to actually access the behaviors of my lawyer. 24 00:01:43,480 --> 00:01:44,090 OK. 25 00:01:44,270 --> 00:01:51,480 So first I need to refer to the name of my object and then I use the dot notation here. 26 00:01:51,560 --> 00:01:54,010 And then I want to actually tell my lawyer to roll. 27 00:01:54,110 --> 00:01:54,640 OK. 28 00:01:54,830 --> 00:02:00,790 So I just need to take in her role as you can see here in this line of code in line 14. 29 00:02:00,890 --> 00:02:03,940 I am telling my lawyer object to roll. 30 00:02:03,980 --> 00:02:04,540 OK. 31 00:02:04,670 --> 00:02:11,100 So now if I run my project as you can see this is the value that is output to the console okay. 32 00:02:11,270 --> 00:02:15,760 Or I may want to actually tell my lion to run. 33 00:02:15,940 --> 00:02:16,510 OK. 34 00:02:16,610 --> 00:02:19,330 So I just need to refer to the name of the object. 35 00:02:19,880 --> 00:02:26,450 And then I use the dot notation here and then I tell my client to run. 36 00:02:26,890 --> 00:02:27,590 OK. 37 00:02:27,980 --> 00:02:34,250 So now if I run on my project as you can see this is the value that is output to the console run ok. 38 00:02:34,250 --> 00:02:37,540 For example my line is now running OK. 39 00:02:37,910 --> 00:02:42,880 And then I want to tell my lawyer to actually fight. 40 00:02:42,890 --> 00:02:43,440 OK. 41 00:02:43,580 --> 00:02:50,750 So again I need to refer to the name of my object that fight and if I get on my project. 42 00:02:50,770 --> 00:02:56,130 Now as you can see my lion is actually fighting now OK. 43 00:02:56,330 --> 00:02:59,100 This is the value that is output to the console fight. 44 00:02:59,310 --> 00:02:59,920 OK. 45 00:02:59,960 --> 00:03:06,680 Or I may want to actually tell my lawyer to sleep so I just need to refer to the name of my object my 46 00:03:06,680 --> 00:03:09,090 lawyer and that sleep. 47 00:03:09,650 --> 00:03:14,510 And if I run my project now as you can see this is the value that is outputted to the console. 48 00:03:14,750 --> 00:03:16,980 For example my lion is now sleeping. 49 00:03:17,000 --> 00:03:17,390 OK. 50 00:03:17,420 --> 00:03:23,690 So first my line is going I actually wrote and then it's going to run and then it's going to fight. 51 00:03:23,990 --> 00:03:27,420 And then my line is going I should sleep OK. 52 00:03:27,650 --> 00:03:37,310 So this is how you can actually access the characteristics or instance variables and the behaviors of 53 00:03:37,310 --> 00:03:38,160 your objects. 54 00:03:38,180 --> 00:03:38,930 OK. 55 00:03:39,620 --> 00:03:41,720 So now let me show you another example. 56 00:03:42,020 --> 00:03:50,290 So first let me actually comment out these lines of code here and here I can actually create another 57 00:03:50,320 --> 00:03:53,510 object of this class. 58 00:03:53,530 --> 00:04:04,800 So I just need to refer to the name of my lion class and the name of my lion object is my second lion. 59 00:04:05,250 --> 00:04:12,960 And then I put an assignment operator here and then I use this keyboard here new and again I need to 60 00:04:12,960 --> 00:04:19,150 refer to the name of my class and that I need to put in a pair of round brackets after my class name 61 00:04:19,170 --> 00:04:19,650 OK. 62 00:04:19,830 --> 00:04:23,600 And then I need to put in a semicolon at the end of my statement. 63 00:04:23,640 --> 00:04:30,630 So now I can actually access the instance variables or behaviors of these. 64 00:04:30,690 --> 00:04:32,080 My second line object. 65 00:04:32,100 --> 00:04:32,560 OK. 66 00:04:32,790 --> 00:04:40,530 So now I want to show you another way of creating objects so like variables we can first declare our 67 00:04:40,620 --> 00:04:42,060 objects. 68 00:04:42,270 --> 00:04:52,200 So now as you can see here in 9:19 I am actually declaring that I am going to create an object from 69 00:04:52,200 --> 00:04:52,990 the lower class. 70 00:04:53,030 --> 00:04:56,510 OK but I didn't actually instantiate this object. 71 00:04:56,520 --> 00:04:56,920 OK. 72 00:04:56,940 --> 00:05:05,820 First before I can actually access the characteristics or behaviors of these Lalia object I need to 73 00:05:05,970 --> 00:05:07,880 first instantiated. 74 00:05:07,890 --> 00:05:14,760 So for example in line to anyone I can instantiate my search like an object I need to refer to the name 75 00:05:14,760 --> 00:05:15,620 of my object. 76 00:05:15,630 --> 00:05:22,990 My second luggin and I puts an assignment operator here and then I put this key word here new. 77 00:05:23,430 --> 00:05:29,560 And then I refer to the name of my class and then I put a pair of round brackets at the end of my class. 78 00:05:29,790 --> 00:05:30,500 OK. 79 00:05:31,170 --> 00:05:37,770 So as you can see here now in line 21 I am actually instantiating my second line object. 80 00:05:37,780 --> 00:05:38,250 OK. 81 00:05:38,460 --> 00:05:44,640 And now I can access the characteristics or behaviors of DS. 82 00:05:44,670 --> 00:05:46,090 My second like an object. 83 00:05:46,090 --> 00:05:46,690 OK. 84 00:05:47,040 --> 00:05:55,470 So I can just take in here system that out that learn and then inside the apprentice's I can just refer 85 00:05:55,470 --> 00:05:58,680 to the name of my object that speed 86 00:06:02,170 --> 00:06:06,580 I want to output the value of the power instance variable to the console. 87 00:06:06,610 --> 00:06:13,470 So I just need to type in here system that out that print to learn and that in say the apprentice's 88 00:06:13,560 --> 00:06:21,120 I need to refer to the name of my object my second life and that power or I may want to access the behaviors 89 00:06:21,300 --> 00:06:22,890 of my life and object. 90 00:06:23,070 --> 00:06:33,960 So I just need to refer to the name of my object my my second line that wrote my second line in thought 91 00:06:34,520 --> 00:06:45,120 Ron my second lie in that fight my second life in that sleep. 92 00:06:45,140 --> 00:06:52,880 So as you can see here I successfully managed to actually access the characteristics and behaviors of 93 00:06:52,880 --> 00:06:53,870 my life and object. 94 00:06:53,870 --> 00:06:54,650 OK. 95 00:06:54,890 --> 00:07:03,320 So now if you are on my project as you can see these are the values of the characteristics or behaviors 96 00:07:03,530 --> 00:07:05,220 of my second line object. 97 00:07:05,240 --> 00:07:05,730 OK. 98 00:07:05,810 --> 00:07:13,710 So now if I actually comment out this line of code here now the eclipse is complaining and is now showing 99 00:07:13,770 --> 00:07:15,450 us lots of errors. 100 00:07:15,450 --> 00:07:16,030 OK. 101 00:07:16,500 --> 00:07:25,560 It's telling us that we need to actually instantiate our object before we can actually access the instance 102 00:07:25,560 --> 00:07:29,290 variables or behaviors of that specific object. 103 00:07:29,340 --> 00:07:35,020 OK so in line 21 we are actually instantiating and it's my second layer and object. 104 00:07:35,040 --> 00:07:35,510 OK. 105 00:07:35,610 --> 00:07:43,950 So that's it for actually objects and methods and that's how you can actually access the characteristics 106 00:07:44,010 --> 00:07:46,700 or the behaviors of your objects. 107 00:07:46,710 --> 00:07:47,220 OK. 108 00:07:47,550 --> 00:07:51,370 So if you have any questions please post the discussion in the course. 109 00:07:51,450 --> 00:07:55,830 Thank you very much for watching and I'll see you in the next tutorial.
