WEBVTT 00:00.960 --> 00:01.640 Hi everyone. 00:01.640 --> 00:02.320 Welcome back. 00:02.360 --> 00:06.240 In this lecture we are going to be coding the similar functionality. 00:06.240 --> 00:12.520 But we are going to be try to implement the same functionality using the coding assistant. 00:12.520 --> 00:15.480 So we hand coded this whole logic right. 00:15.520 --> 00:20.200 And also we ran the program and then validated the program. 00:20.200 --> 00:27.000 Now I'm going to show you one additional approach of coding the same logic using our GitHub copilot. 00:27.160 --> 00:28.400 So in your package. 00:28.400 --> 00:33.120 So if you open the stream Gatherer's package you will see a markdown file over here. 00:33.400 --> 00:41.680 So this markdown file has all the prompts that are required to replicate the code we have been doing 00:41.680 --> 00:42.200 so far. 00:42.200 --> 00:48.240 And I have the prompts available pretty much for all the functionalities that we are going to be exploring 00:48.240 --> 00:50.920 for the stream Gatherer's API. 00:51.080 --> 00:56.080 So in this case, what I'm going to do, let's say you want to do the same coding logic, right? 00:56.120 --> 01:01.960 But you still don't want to hand code it basically the traditional way of coding everything by yourself. 01:02.160 --> 01:07.120 Then what you can do is you can leverage this stream Gatherer's markdown file, and then you can see 01:07.220 --> 01:13.460 that I have a prompt named Windows Fixed Operations certain creating fixed size groups. 01:13.460 --> 01:16.740 So I'll create a table of contents also over here. 01:17.580 --> 01:17.940 There you go. 01:17.980 --> 01:19.380 We have the table of contents. 01:19.380 --> 01:22.100 So it has the windows fixed operations. 01:22.100 --> 01:24.660 If we go to this one it talks about this one right. 01:24.700 --> 01:28.820 So I'm going to be copying this and then open the copilot chat. 01:28.820 --> 01:30.180 I'm not going to use the agent mode. 01:30.180 --> 01:30.500 For now. 01:30.500 --> 01:31.820 Let's use the ask mode. 01:32.020 --> 01:33.460 Let's create a brand new chat. 01:33.660 --> 01:34.300 There you go. 01:34.540 --> 01:36.940 So in here I'm going to be placing this one. 01:36.940 --> 01:38.620 So what is the prompt actually. 01:38.620 --> 01:45.020 So the prompt says that create a method that demonstrates the fixed size windowing of movie collections. 01:45.020 --> 01:47.060 And this is the name of the function it's going to be. 01:47.060 --> 01:48.900 That's the expected function signature. 01:49.060 --> 01:53.860 And then I'm going to be passing these requirements to the LM okay. 01:53.900 --> 01:57.900 So in this case the section header should be windows fixed. 01:57.940 --> 01:59.060 That's what this one is. 01:59.060 --> 02:01.060 Basically this is the print line. 02:01.260 --> 02:04.380 Let me put this in a side by side view and then explain this code okay. 02:04.420 --> 02:09.300 And then what we are doing is that hey the gather that window fixed three to group the movies into windows 02:09.300 --> 02:15.480 of three and process each window as a separate collection and print window contents with proper formatting, 02:15.640 --> 02:18.800 and display each movie with indentation of this one. 02:18.840 --> 02:25.920 Add spacing between windows for clarity, and then handle classes where final window may contain fewer 02:25.920 --> 02:27.040 than three movies. 02:27.120 --> 02:27.760 So here. 02:27.760 --> 02:29.880 This is a very descriptive prompt. 02:29.880 --> 02:35.160 The reason why I'm giving this descriptive is that I would like to have the same code that I have done 02:35.160 --> 02:40.400 to be replicated, but when you are working on some features, let's say you have some thoughts on your 02:40.400 --> 02:40.800 head. 02:40.840 --> 02:44.520 You can actually provide those thoughts in simple manner. 02:44.720 --> 02:48.320 You should still be able to see the similar code replicated for you. 02:48.480 --> 02:53.480 Okay, so now I'm going to pass this prompt and then ask it to write the code for me. 02:53.480 --> 02:57.200 So I'm not doing agent mode, I'm just doing the ask mode okay. 02:57.240 --> 02:58.240 And then press enter. 03:02.160 --> 03:08.000 So here you can see write the same code that we wrote over here is being written for us. 03:08.280 --> 03:10.320 So it says that this is a sysout. 03:10.320 --> 03:12.640 And then we have the gather window fixed of three. 03:12.680 --> 03:18.960 And then you have the whole code being printed in the console after the gatherer gathers the windows 03:18.960 --> 03:20.260 of fixed size three. 03:20.300 --> 03:21.660 And then you can see that. 03:21.700 --> 03:23.540 Here is a quick summary of what's done. 03:23.580 --> 03:26.380 Here we have the group stream into fixed size windows. 03:26.620 --> 03:28.300 Handles the last window gracefully. 03:28.620 --> 03:30.700 And then printing the title over here. 03:30.700 --> 03:33.300 Now you can actually also ask more questions on. 03:33.340 --> 03:37.820 That can you explain more about the windows fixed. 03:40.820 --> 03:44.100 So here it gives you some different examples actually. 03:44.100 --> 03:46.500 So here it gave you a very simple example. 03:46.500 --> 03:48.380 Here we have a list of integers. 03:48.380 --> 03:50.860 And then this is the gather function. 03:50.860 --> 03:53.300 And then this is the output how it's going to be. 03:53.340 --> 03:57.060 And it also talks about what is the key characteristics over here. 03:57.060 --> 04:00.500 And then you can see that with 12 movies how the result is going to be. 04:00.660 --> 04:05.500 And comparison with windows lining is something which we are going to look in the next lecture. 04:05.500 --> 04:07.460 But this is a beauty of this coding assistant. 04:07.500 --> 04:10.540 Now what I'm going to do is that I'm going to remove this whole code. 04:10.620 --> 04:11.060 Okay. 04:11.260 --> 04:14.500 Now I'm going to ask the agent to make the change for me. 04:14.500 --> 04:16.420 So now I'm going to go to the agent mode. 04:16.900 --> 04:24.260 Can you please make the change in the demo dot Java file, please use the initial code that you generated 04:24.260 --> 04:25.140 for movies. 04:25.140 --> 04:26.310 So I'm going to press enter. 04:26.350 --> 04:26.550 Okay. 04:26.590 --> 04:31.110 So this is an agent mode which is going to go to this file and then make the change for you. 04:31.150 --> 04:33.870 You'll be able to see it as it's doing the changes. 04:33.870 --> 04:38.750 So let me close this one open so you can see that it is going to be starting to edit. 04:38.790 --> 04:39.590 You see this right. 04:39.590 --> 04:41.350 It edited the file for you. 04:41.350 --> 04:45.670 So here we have the similar code which is movie stream gather for each. 04:45.870 --> 04:48.950 It's the same code that we wrote beforehand. 04:48.990 --> 04:50.750 Now you have this code readily available. 04:50.790 --> 04:55.070 All you got to do is give this prompt and it will write the code for you. 04:55.110 --> 05:00.630 Let's say if you are really lazy to type in, but you still understand the complete concept, if you 05:00.630 --> 05:05.230 want the AA to do the for you, it will very much do the job for you without any issues. 05:05.270 --> 05:09.790 Now what I'm going to do, I'm going to be accepting this change, and then I'm going to run the program 05:09.790 --> 05:12.110 again, and then I'll show you the result. 05:13.990 --> 05:14.710 There you go. 05:14.750 --> 05:17.110 It's the same result that we have over here. 05:17.110 --> 05:22.790 So this is the beauty of these copilot assistant where you don't have to hard code everything. 05:23.030 --> 05:25.710 All you got to do is provide a proper prompt. 05:25.750 --> 05:28.870 It will write the code for you without any issues. 05:28.870 --> 05:31.870 And this also improves our speed of learning. 05:31.870 --> 05:37.690 And also from a developer standpoint, all you got to do is you ask the prompt, the LM will write the 05:37.690 --> 05:38.530 code for you. 05:38.570 --> 05:42.810 You will be like a human in the loop who validates the code is good or bad. 05:43.050 --> 05:48.090 If the code generated is not aligned to what you are thinking, all you got to do is give it a feedback. 05:48.090 --> 05:49.770 It will make the changes for you. 05:49.770 --> 05:54.730 So in the following lectures I'll be hand coding this stream gatherer API concepts. 05:54.730 --> 05:59.810 But this is something which I would like to show you as a modern way of learning things. 05:59.810 --> 06:02.210 Modern way of coding concepts. 06:02.250 --> 06:04.050 Modern way of building applications. 06:04.050 --> 06:11.050 Using these AI assistants, these AI assistants are going to stay and it's going to continuously get 06:11.050 --> 06:11.570 better. 06:11.650 --> 06:17.090 I hope you all were able to successfully code this windows fixed concept using the AI assistant. 06:17.090 --> 06:21.970 And in your case, all these concepts will be available as part of these prompts. 06:22.330 --> 06:28.730 Um, please go ahead and start using these concepts of using AI assistant to write the code for you, 06:28.770 --> 06:35.090 which is again going to improve the developers productivity and also the speed of learning as you learn 06:35.130 --> 06:36.010 new concepts. 06:36.010 --> 06:37.530 This marks the end of this lecture. 06:37.530 --> 06:38.610 Thank you for watching.
