[MUSIC] [MUSIC] Hello and welcome to this tutorial on the installation and configuration of the IDE used in the introductory course on programming: IntelliJ IDEA. To download this software, I invite you to open a browser and go to the jetbrains.com page. On this page you can find the link to the JetBrains installer, either by navigating the page, or by or by going to the navigation bar, select Developper Tools and find link for IntelliJ IDEA, which is, the IDEA software that we are going to use we will use during the course. Select this link and click on the the Download button. If the site did not find your operating system, you can change it by clicking on one of the tabs here. Once you are on the right operating system, find the download button for the the Community version which is free. Press Download, and save the file to your the file on your computer. This download may take a while, and then we'll find you when this one has finished. Once this download is finished, you can run it you can run it directly from your download bar of your browser or by going to your Download folder on your computer and opening the file by double clicking on it. Once this file is opened, you should potentially grant it some permissions grant it some permissions, including permission to install things on your computer. On Windows, this is the window you just just seen, and the elevation prompt. Select Run and Yes, respectively. Once you have arrived at this page, press to this page, press Next. Let it install in the default folder, and then press Next and Install. This procedure may take a few take a few minutes, and we will find you once she has finished. Once the installation is complete, you will now see this page. So select the option Run IntelliJ IDEA Community Edition, and Finish, and let the software start. Once started, you will see this page: the dashboard. In order to get started and to be able to code in Scala, the programming language taught in the course, you will need course, you will need the Scala plug-in. So go to the Plugins tab, here on the left, and find the Scala plug-in. It is either at the top of the Featured list, and if it's not, you can find it by typing Scala in the search bar. Select Install and let the plug-in to install. [Noise] Once this Scala plug-in is finished from installing itself, you will be asked to restart the IDE, you can do this by by pressing this button. Once the IDE is restarted, it is time to start a time to start a new project. Go to the right side of your window and select New Project. Here, find the Scala tab, and the IDEA option. Press Next. Now comes the slightly more critical part of the critical part of the installation. Find a project name that suits you. we'll say Test1. You will need a version of of OpenKit Java, which you can select by clicking on this tab. I recommend you to download a new JDK at version 16 of the vendor Eclipse Temurin AdoptOpenJDK HotSpot. This installation has been tested and working for the purposes of the course. Let it download and, once it has it has downloaded, it will be displayed here. Next, you will need to select a Scala SDK. If you can't find one here, you will have to create a Scala SDK, so press the Create button. Here you can either select a version that you have already installed, or download a new one, by pressing Download, here at the bottom, and selecting the latest version in 2.13.6. This is the stable version with which we teach the course. Once version 2.13.6 is selected, click on Finish, and you can start coding. To code, you will have to create a file which contains a main function, as we have seen in class. To do this, go to the source folder here on the left, right click, select New, Scala Class. Here, in the file type drop-down list of file types, select Object, and we will call this object Hello. To verify that your Scala SDK installation has been done correctly, type the word main. If this prompt appears with main Template for main method, in it, and that, by clicking on it or pressing Enter, it gives you this block of code, then the installation has been completed correctly. Here, in order to demonstrate that the whole thing works, we will ask our program to print the text, Hello, World! which is the initial project of each programming language. To check that this runs correctly, find the green triangles, here on the left. If the green triangle does not exist on your IDE, it may be that your IDE has not finished indexing the language. If something appears in this this area at the bottom right, by saying Indexing JDK, or something like that, is that it hasn't finished yet and, so you have to let it finish. Once this triangle appears, you can click on it, and then, press Run 'the name of your object'. This will create a build, and this build, when finished, will show a piece of window with some text in it: Hello, World! Everything works correctly. So now you have installed IntelliJ IDE, which we will use for the course, correctly configured the JDK that works best, and, as a result, the SDK for the Scala language, which we teach in the course. Thank you for attending this tutorial. [MUSIC] [MUSIC]
