WEBVTT 00:00.040 --> 00:00.520 Hi everyone. 00:00.520 --> 00:01.120 Welcome back. 00:01.120 --> 00:05.920 In this lecture I would like to take a step back and then look at where we are at this point of the 00:05.920 --> 00:06.400 course. 00:06.400 --> 00:10.000 So far we have covered all the Java eight features. 00:10.000 --> 00:15.120 We have looked at lambdas, streams, optionals and new date time APIs. 00:15.120 --> 00:18.480 So basically, the first part of the course that I promised came to an end. 00:18.520 --> 00:23.240 Now it's time to look at all the features from Java nine and beyond. 00:23.240 --> 00:29.000 So we are going to be exploring all these features that are listed in the Java nine and beyond section 00:29.000 --> 00:29.480 here. 00:29.480 --> 00:34.000 So for this purpose, we are going to be working on a different project starting from this particular 00:34.000 --> 00:34.520 lecture. 00:34.520 --> 00:40.200 So in this lecture we are going to be setting up the base project for exploring all the Java nine features 00:40.200 --> 00:40.840 and beyond. 00:40.880 --> 00:42.640 Let's go back to the GitHub repo. 00:42.640 --> 00:47.760 And then I would like to download the base project from GitHub repo and then set it up in our IntelliJ. 00:47.800 --> 00:48.160 Okay. 00:48.200 --> 00:50.680 So I'm going to be going back to the GitHub repo. 00:50.720 --> 00:51.200 There you go. 00:51.240 --> 00:52.440 The modern Java v2. 00:52.480 --> 00:53.240 That's a repo. 00:53.280 --> 00:55.120 What I'm going to do I'm going to click on this one. 00:55.120 --> 00:57.640 And then I'm going to be downloading the zip file. 00:57.640 --> 00:58.240 There you go. 00:58.280 --> 00:59.600 The zip file got downloaded. 00:59.600 --> 01:00.640 So this is where it is. 01:00.680 --> 01:03.480 And then I'm going to be going inside this project. 01:03.480 --> 01:06.560 And in the project you will have something called modern Java. 01:06.600 --> 01:08.440 Okay I'm going to copy this one. 01:08.440 --> 01:11.520 And then I'm going to go to my modern Java v2 folder here. 01:11.520 --> 01:13.880 And then I'm going to place it over here. 01:13.880 --> 01:18.560 And you need to ensure that you are on the main branch, because this is a branch which has the starter 01:18.560 --> 01:20.840 code for the modern Java project. 01:20.840 --> 01:23.920 So now what we are going to do I'm going to go back to the IntelliJ. 01:23.960 --> 01:27.280 So in IntelliJ I'm going to click on the file and then click on the new. 01:27.280 --> 01:30.680 And then I'm going to select project from existing sources. 01:30.680 --> 01:31.560 Click on this one. 01:31.560 --> 01:35.640 And then we are going to go to the folder where I have copied and pasted that. 01:35.640 --> 01:36.880 So it's inside this one. 01:36.880 --> 01:38.760 Select this project and then click open. 01:38.760 --> 01:41.360 So this will open the project in a new window. 01:41.360 --> 01:44.240 And this project is going to be a Gradle based project. 01:44.280 --> 01:46.840 We will not be making any changes to the Gradle project. 01:46.840 --> 01:48.920 It's just that you need to select this build tool. 01:48.960 --> 01:53.480 Even if you have not worked on Gradle, you don't have to worry about it because we will not be making 01:53.480 --> 01:56.360 any changes to this particular bill file at all. 01:56.360 --> 01:58.480 So click Gradle here and then click create. 01:58.480 --> 02:02.440 So this is going to be importing the project in a new IntelliJ window. 02:02.480 --> 02:03.000 There you go. 02:03.040 --> 02:05.480 Or it might be opening in a tab in your case. 02:05.480 --> 02:09.040 And you can see that in the bottom it is importing the Gradle project. 02:09.040 --> 02:09.440 There you go. 02:09.480 --> 02:10.800 The project got imported. 02:10.800 --> 02:15.640 And then the one thing that I want to show you is that if you open the Build.gradle file, which is 02:15.640 --> 02:21.280 at the base path, the version of Java is being configured in this particular file. 02:21.280 --> 02:24.960 So if you take a look at it we have this sub project section. 02:24.960 --> 02:30.320 And this sub project section actually has a configuration where we define the source compatibility as 02:30.360 --> 02:31.440 version 25. 02:31.680 --> 02:37.320 This means we are using the latest and greatest version of Java at the time of recording this lecture. 02:37.320 --> 02:42.440 And this is the latest LTS version which is the long term stable version. 02:42.760 --> 02:43.280 Okay. 02:43.320 --> 02:45.280 So now we have this over here. 02:45.280 --> 02:51.880 And the next thing is that if we go to the settings, you need to ensure that we are using the Gradle 02:51.880 --> 02:53.880 JVM also as Java 25. 02:53.880 --> 02:57.440 So if you open the settings you'll go to the build execution in development. 02:57.440 --> 03:00.360 And then we will have the Build Tool section over here. 03:00.400 --> 03:04.720 Click on the Gradle and then you select the Gradle JVM as Java 25. 03:04.720 --> 03:07.400 So you will have all these different versions available. 03:07.640 --> 03:10.440 These are the different versions of Java I have in this machine. 03:10.440 --> 03:13.240 So Java 21, Java 17, Java 11. 03:13.240 --> 03:17.440 But the one that I'm going to be choosing is that eclipse 25. 03:17.480 --> 03:20.640 This is the one that we installed in our previous lecture. 03:20.640 --> 03:22.600 So click apply and then click okay okay. 03:22.640 --> 03:24.600 So you can see that it's being refreshing. 03:24.600 --> 03:25.680 Something over here. 03:25.720 --> 03:32.200 This is a signal that we are actually configuring this workspace for Java 25 okay. 03:32.240 --> 03:35.190 So other option is basically opening this window. 03:35.190 --> 03:40.510 So in this window you still need to choose the SDK as Java 25. 03:40.910 --> 03:42.430 Let's see how to go to this window. 03:42.430 --> 03:45.750 Right click on this project open module settings. 03:45.750 --> 03:49.350 If you open that, this is the one which gives you this project structure. 03:49.510 --> 03:51.230 And then click on the project over here. 03:51.230 --> 03:55.750 So you need to have the SDK as Java 25 and the language level. 03:55.750 --> 03:59.390 I'm going to set it up as 25 over here apply. 04:00.230 --> 04:08.070 And then okay so when you have these setup completed this means your workspace is set up for Java 25. 04:08.270 --> 04:14.910 Now what I'm going to do is I'm going to open one of the actual project module and then go to the main. 04:15.150 --> 04:18.590 And then we are going to be selecting the war over here. 04:18.590 --> 04:21.070 So I'm going to be running this particular example. 04:21.070 --> 04:24.070 So this example should execute as expected. 04:24.110 --> 04:24.670 There you go. 04:24.990 --> 04:31.790 As long as you see this result this means our project is configured successfully for Java 25. 04:31.950 --> 04:34.030 And the code is working as expected. 04:34.230 --> 04:39.710 Starting from next lecture, we will explore all the features from Java nine until the latest stable 04:39.710 --> 04:42.070 version at the time of recording this lecture. 04:42.110 --> 04:43.670 This marks the end of this lecture. 04:43.670 --> 04:44.750 Thank you for watching.
