1 00:00:00,290 --> 00:00:00,990 OK. 2 00:00:01,250 --> 00:00:05,600 So let's actually test other classes again. 3 00:00:05,630 --> 00:00:12,410 We need to just right click on these classes run as job application and this time that I actually used 4 00:00:12,410 --> 00:00:14,310 my class actually. 5 00:00:14,330 --> 00:00:14,960 OK. 6 00:00:15,110 --> 00:00:19,580 Again as you can see this is going to show us the high from my last message. 7 00:00:19,610 --> 00:00:20,650 OK. 8 00:00:21,230 --> 00:00:23,730 So let's actually test another class. 9 00:00:23,870 --> 00:00:29,890 You can actually in order to run your application you can click on this play button here. 10 00:00:30,020 --> 00:00:33,010 It's going to show us that actually the high from my class. 11 00:00:33,020 --> 00:00:39,980 But if you want to choose another class or just right click on my project run as an job application 12 00:00:40,670 --> 00:00:43,420 and here I want to choose the card class. 13 00:00:43,430 --> 00:00:44,090 OK. 14 00:00:44,310 --> 00:00:46,040 And click on OK. 15 00:00:46,310 --> 00:00:48,670 And as you can see it's going to show us nothing. 16 00:00:48,680 --> 00:00:52,070 So let's go inside the Carter java file. 17 00:00:52,640 --> 00:00:58,580 As you can see here we've got the car class here and inside the car class we've got the main method. 18 00:00:58,580 --> 00:00:59,980 This is the starting point. 19 00:00:59,980 --> 00:01:03,920 We're actually running our Java codes. 20 00:01:04,090 --> 00:01:09,340 And as you can see here inside the main method there are no statements here. 21 00:01:09,400 --> 00:01:16,700 So that's why we saw nothing when we actually wanted to execute the statements inside this method. 22 00:01:16,780 --> 00:01:17,320 OK. 23 00:01:17,470 --> 00:01:26,530 So let's actually put in a statement here system that out that Prince Len McKay and inside Apprentice's 24 00:01:26,560 --> 00:01:31,830 I wanna towplane high from car. 25 00:01:32,560 --> 00:01:33,190 OK. 26 00:01:33,550 --> 00:01:40,390 So we need to put in the semi-colon at the end of the statement and let's actually run this class again 27 00:01:41,030 --> 00:01:46,070 like like underclasses project run as job application. 28 00:01:46,450 --> 00:01:48,500 And this time choose car class. 29 00:01:48,510 --> 00:01:50,230 OK. 30 00:01:50,530 --> 00:01:51,320 OK. 31 00:01:51,340 --> 00:01:52,170 That's correct. 32 00:01:52,270 --> 00:01:58,760 And as you can see here the console is going to show us the high from car message. 33 00:01:58,770 --> 00:01:59,490 OK. 34 00:01:59,950 --> 00:02:03,280 It's going to actually execute this code here. 35 00:02:03,340 --> 00:02:11,910 Now I want to actually teach you another concept as you can see there is a smart class here. 36 00:02:11,980 --> 00:02:13,380 There is animal class year. 37 00:02:13,390 --> 00:02:14,930 This is the Animal class. 38 00:02:15,090 --> 00:02:19,500 And let's actually run this project again and see what happens. 39 00:02:19,900 --> 00:02:20,530 OK. 40 00:02:20,710 --> 00:02:25,740 As you can see these are the different Java classes that we have created earlier. 41 00:02:25,930 --> 00:02:26,470 OK. 42 00:02:26,620 --> 00:02:29,410 The car class my class and sport class. 43 00:02:29,530 --> 00:02:31,730 But where is the Atom class. 44 00:02:32,020 --> 00:02:35,590 OK so let's actually see what's happening here. 45 00:02:35,650 --> 00:02:38,260 There is no main method. 46 00:02:38,620 --> 00:02:43,830 Inside the Animal class but there is a main method inside the car class. 47 00:02:43,840 --> 00:02:49,840 There is a main effort inside my class and there is also a main Inside Sport class. 48 00:02:50,200 --> 00:02:50,980 OK. 49 00:02:51,200 --> 00:02:56,160 Now let's actually declare our main event inside the Animal class and see what happens. 50 00:02:56,200 --> 00:02:56,790 OK. 51 00:02:57,160 --> 00:03:10,950 Public static void main and inside Apprentice's stream through the chapiter as brackets and arcs. 52 00:03:10,960 --> 00:03:11,690 OK. 53 00:03:11,950 --> 00:03:14,690 And then we need to open and close our main effort. 54 00:03:14,740 --> 00:03:19,960 OK so I'm not going to actually put any statements here. 55 00:03:20,170 --> 00:03:24,150 So let's actually run this project again and see what happens. 56 00:03:24,260 --> 00:03:26,720 Ran as job application. 57 00:03:26,800 --> 00:03:30,890 So as you can see here there is a there's an Animal class here. 58 00:03:31,150 --> 00:03:39,640 So now we understand that if we don't create if we actually don't declare a main of it in our class. 59 00:03:39,640 --> 00:03:42,430 Java won't allow us to run our class. 60 00:03:42,490 --> 00:03:43,890 OK. 61 00:03:44,530 --> 00:03:47,450 Actually no statements will be executed. 62 00:03:47,640 --> 00:03:47,910 OK. 63 00:03:47,920 --> 00:03:53,970 If you actually don't declare our main method in inside the class. 64 00:03:53,980 --> 00:03:55,090 So thanks for watching. 65 00:03:55,090 --> 00:03:57,920 I think that's enough for this tutorial. 66 00:03:58,580 --> 00:04:00,570 I'll see you in the next tutorial.
