3 3 00:00:03,963 --> 00:00:05,650 Let's write some code. 4 4 00:00:05,650 --> 00:00:07,370 So looking at our to-do list here, 5 5 00:00:07,370 --> 00:00:08,826 or our step-by-step, 6 6 00:00:08,826 --> 00:00:10,295 the first thing we need to do is 7 7 00:00:10,295 --> 00:00:14,128 define the dependency interface and the class. 8 8 00:00:15,070 --> 00:00:19,165 And we'll make use of that same dependency from earlier, 9 9 00:00:19,165 --> 00:00:22,432 fortune service and happy fortune service, 10 10 00:00:22,432 --> 00:00:24,509 but we'll go ahead and cut the code again from scratch 11 11 00:00:24,509 --> 00:00:26,204 just so we're all on track 12 12 00:00:26,204 --> 00:00:28,090 and everything is sinked up. 13 13 00:00:28,090 --> 00:00:29,665 I'll simply do a right click, 14 14 00:00:29,665 --> 00:00:31,582 I'll say new interface. 15 15 00:00:33,700 --> 00:00:38,514 And the name of this interface is FortuneService. 16 16 00:00:38,514 --> 00:00:39,399 Another name there, 17 17 00:00:39,399 --> 00:00:41,126 I keep all the other defaults 18 18 00:00:41,126 --> 00:00:42,543 and I hit finish. 19 19 00:00:45,608 --> 00:00:48,294 So at this point I have a very basic fortune service. 20 20 00:00:48,294 --> 00:00:50,666 There's nothing inside of it. 21 21 00:00:50,666 --> 00:00:53,390 I'm gonna define just one method here, 22 22 00:00:53,390 --> 00:00:55,765 this method will be called 23 23 00:00:55,765 --> 00:00:56,682 getFortune. 24 24 00:00:57,609 --> 00:00:59,529 And open paren, close paren, and a semicolon, 25 25 00:00:59,529 --> 00:01:00,362 and that's it. 26 26 00:01:00,362 --> 00:01:01,374 Somethin' very simple. 27 27 00:01:01,374 --> 00:01:02,597 Not much coding. 28 28 00:01:02,597 --> 00:01:04,559 We like to keep it short 29 29 00:01:04,559 --> 00:01:06,976 and we like to keep it sweet. 30 30 00:01:09,591 --> 00:01:11,720 So there's our fortune service, 31 31 00:01:11,720 --> 00:01:13,935 now what we wanna do is actually create a class 32 32 00:01:13,935 --> 00:01:16,457 that'll actually implement this interface. 33 33 00:01:16,457 --> 00:01:18,687 So I'll move back over here to my package, 34 34 00:01:18,687 --> 00:01:22,270 I'll do a right click, I'll say new, class. 35 35 00:01:26,297 --> 00:01:30,464 Now the name of this class will be HappyFortuneService. 36 36 00:01:31,328 --> 00:01:34,441 So that's the name and then this class 37 37 00:01:34,441 --> 00:01:36,598 will actually implement an interface. 38 38 00:01:36,598 --> 00:01:38,532 So down in the interfaces section, 39 39 00:01:38,532 --> 00:01:41,858 let's click on that button to the right called add. 40 40 00:01:41,858 --> 00:01:44,723 And the name of the interface that we're looking for 41 41 00:01:44,723 --> 00:01:46,706 here is called FortuneService. 42 42 00:01:46,706 --> 00:01:48,221 So I just type in fortune up top, 43 43 00:01:48,221 --> 00:01:50,317 you'll get this FortuneService listing there 44 44 00:01:50,317 --> 00:01:51,725 as a matching item. 45 45 00:01:51,725 --> 00:01:54,549 Then go ahead and hit on the okay button. 46 46 00:01:54,549 --> 00:01:57,029 So our interfaces section should be updated 47 47 00:01:57,029 --> 00:01:58,720 with FortuneService. 48 48 00:01:58,720 --> 00:01:59,796 Looks good. 49 49 00:01:59,796 --> 00:02:01,127 Let's keep all the other defaults 50 50 00:02:01,127 --> 00:02:03,794 and let's hit the finish button. 51 51 00:02:04,689 --> 00:02:05,629 Okay, good. 52 52 00:02:05,629 --> 00:02:06,462 Here we go. 53 53 00:02:06,462 --> 00:02:08,339 So we have our HappyFortuneService implements 54 54 00:02:08,339 --> 00:02:09,245 FortuneService, 55 55 00:02:09,245 --> 00:02:11,118 we're simply gonna give a very basic 56 56 00:02:11,118 --> 00:02:12,696 implementation here. 57 57 00:02:12,696 --> 00:02:15,251 On line seven, I'll simply say return, 58 58 00:02:15,251 --> 00:02:18,501 and I will say today is your lucky day. 59 59 00:02:20,604 --> 00:02:22,127 And I'll add the double quote there 60 60 00:02:22,127 --> 00:02:23,014 and that's it. 61 61 00:02:23,014 --> 00:02:26,327 So that's a basic implementation here of this 62 62 00:02:26,327 --> 00:02:27,994 HappyFortuneService. 63 63 00:02:29,412 --> 00:02:30,318 This looks good. 64 64 00:02:30,318 --> 00:02:31,736 Now the one thing that we're gonna do different 65 65 00:02:31,736 --> 00:02:33,457 that we didn't do earlier in the videos 66 66 00:02:33,457 --> 00:02:36,301 is that we're gonna add this @Component annotation. 67 67 00:02:36,301 --> 00:02:39,384 Remember Spring will scan our package 68 68 00:02:40,236 --> 00:02:42,331 and it'll register all components. 69 69 00:02:42,331 --> 00:02:44,110 So we want this HappyFortuneService 70 70 00:02:44,110 --> 00:02:46,365 to be a component that's registered. 71 71 00:02:46,365 --> 00:02:50,532 That looks good and I think we're in good shape so far. 72 72 00:02:58,072 --> 00:03:00,066 Now the next thing we wanna do is we wanna enhance 73 73 00:03:00,066 --> 00:03:01,512 our coach interface. 74 74 00:03:01,512 --> 00:03:04,223 We actually wanna add a method to the coach interface. 75 75 00:03:04,223 --> 00:03:07,232 Right now the coach can give us daily workouts 76 76 00:03:07,232 --> 00:03:10,184 but we also want the coach to be able to give us 77 77 00:03:10,184 --> 00:03:12,294 our daily fortune. 78 78 00:03:12,294 --> 00:03:13,680 So in coach dot java, 79 79 00:03:13,680 --> 00:03:15,700 I'm gonna add a new method here called 80 80 00:03:15,700 --> 00:03:18,867 GetDailyFortune that returns a string. 81 81 00:03:20,681 --> 00:03:21,514 And that's it. 82 82 00:03:21,514 --> 00:03:24,258 We keep it very simple for right now. 83 83 00:03:24,258 --> 00:03:25,165 Okay, great. 84 84 00:03:25,165 --> 00:03:26,516 This looks good so far. 85 85 00:03:26,516 --> 00:03:27,349 Good job. 6777
