English In this video we're going to go ahead and download and install IntelliJ IDEA, which is the editor or the IDE that we're going to be using in this course for our programs. Now this particular video is for Windows platform. Now if you're running a Mac or you're running on Linux, there are separate videos for both those operating systems in this section of the course, so I refer to those videos as appropriate or if you're on Windows you're in the right place. So the first thing to do is to go to the website, that's the site all the creators of this IntelliJ IDEA product that we going to be using, one you get there and come down here and click on IntelliJ, if it's showing if by chance it's not showing for some reason, go to IDE or IDEs and click on IntelliJ IDEA, either way click on that link to go to that page, next option is to click on download, you're then presented with two options to download either the Ultimate Edition or the Community Edition. Now I'm going to go ahead and download the Community Edition, then we're going to talk a little bit about it once it's downloading just to save a bit of time, so I clicked on download as you saw it should pop up you can see down the bottom, I'm going to click on save to save that, I'm just going to go back just to show you the page with the Ultimate Edition and the Community Edition and just talk about they're both there on both versions there. Now the Ultimate Edition is the commercial product, so if you want to use that past a trial period you will need to pay money for it and you'll need to pay JetBrains for that. The Community Edition on the other hand is completely free and you'll never have to pay anything for it, so it can be a good choice in many cases to take the free and open-source version, but if you do want to have access to other commercial features for example Java Enterprise Edition and using other frameworks that aren't compatible or aren't available in the free version, the Community Edition you can take this option here and with the Ultimate Edition there's a 30-day trial option so you can try it out for free for 30 days and then after that ordinarily you would have to pay for it, so refer to that if you decide to download the Ultimate Edition, otherwise as you saw me doing this video I've downloaded to the community edition and that will certainly work okay in this course. Alright so now that that's downloaded, I'm gonna click on run so depending on your browser, you may need to navigate to the folder where you've downloaded it in any event to start up the installer, in this case I've clicked run and it's going to give us the option to start installing, you're going to close the browser down now and they're gonna go through and follow the setup process I'm gonna click on next I'm going to just assume or select or use the default location, the destination folder, don't need to change that. Now the other option you'll need to know is whether you're running a 32-bit or a 64-bit version of Windows. Now in the previous video, I've shown you how to do that in the JDK the Java development kit video I showed you how to determine whether you're running a 32-bit or 64-bit so depending on what you found when you're downloading that video, select the relevant option in my case I was running a 64-bit edition so I'm going to select that obviously you'd select a 32-bit if that's what you're running on your windows is running under 32-bit version and I suggest you click these three associations, there's check boxes and that just enables those particular languages, those files they've got that file extension to be opened up in IntelliJ and that's usually what you want to do and click on next, click on install and that's now going ahead and installing IntelliJ IDEA, so I'm just going to fast forward this video now to save a bit of time and we come back after it's finished installing. Alright, so you can say it's just about finished now we'll just let that finish off. Alright so it's now actually finished the next option is just to click on the check box, so we can run IntelliJ and that's an irrespective of whether you've downloaded the ultimate or in this case the Community Edition, so click on that and click on finish and it's going to start up IntelliJ for us. Now usually you'll see this option and it's coming up telling us that we've got an option to try and import some settings. Now this would be useful if you're running IntelliJ or you have installed a previous version and you want to retain the settings that you've configured in this case I haven't actually installed IntelliJ on this computer and this is most likely the option you'll see, so you can click on do not import settings otherwise there's a location usually selected or found by IntelliJ and you could select that and get IntelliJ to import those settings and use them in your installation of IntelliJ, but in my case I'm going to leave the default do not import settings and click ok. Alright next we need to go through a configuration section to just set up some settings and to tell IntelliJ what options we want, now this is the theme and you can see the one on the left has got a white background the one on the right has got a darker background, we can choose either so select which one you would like prefer to work with knowing that you can always change it later I'm going to select the one with the white background and click on next. Now there's a series of plugins on this screen and you can choose all sorts of things and what I suggest you do generally is leave this as it is now and come back later if you decide you want to install plug-ins and just the other thing to note is if you're running the ultimate version of IntelliJ you'll actually have more options to install plug-ins about I'm just going to click on next, same deal here if we want to change or install these two things which we aren't going to use in this particular course, you can do that now but I'm going to skip both of those and click on start using IntelliJ IDEA and you can see that that's now loaded up IntelliJ. Now the next step we need to do is actually configure the Java development kit and we need to do that so that we can actually program in this course, so the way to do that is to click on configure and click on project defaults and then select project structure and that'll bring us to the screen and if you're not seeing project SDK, showing there, you might have been clicked in another area so just make sure you clicked a project and that will show that and you click on the drop down just to see whether there's been one configured but in my case you can see it says no SDK, SDK meaning software development kit, so what we need to do is create one so that so we can actually program within IntelliJ, so what we need to do is basically associate the Java development kit that we've installed previously with IntelliJ, so to do that I'm going to click on new and I'm going to select JDK. Now what we need to do is navigate to the folder where we installed the Java development kit and I did talk about that in the Java development kit installation video, the need to know where that was installed and if you recall that on my machine in that video it was installed in the Program Files folder, so navigate to that folder and go into the Java subfolder and you'll see that there's these two folder locations - JDK and the JRE and this number may change depending on when you're watching this video but the one you want to select is the JDK then go ahead and click on JDK and click on ok and just before I click on ok, it is important to have a look and make sure that you've selected program files and not program files x86 because there's two directories in there that are very similar and you can see there's this program files x86, if I open that up and have a look you'll see that there's no Java folder there, so a common question will come up far from students not being able to follow the Java folder and that's because they're looking in the Program Files x86 but in my case close it back up again we're in the right place here we're in the Program Files Java and I've clicked on the JDK and make sure you don't click on the JRE because we need the JDK because that's the development kit which includes the extra tools that we need to be able to program ,so I'm going to click on ok with that selected and you can see any other project SDK has been changed here in the past that was known as SDK right now I've got an option there so that's not selected automatically make sure that is selected and the next thing you want to do here is make sure that project language level we can actually see that it says SDK default eight so it is possible to choose other versions, but you won't need to do that at this time so I'll leave that particular version selected, so we don't need to change anything else on this page, I'm going to click on ok we've got a few other settings that we need to configure and then we can actually move on to start our working with program code, so we come back here and click on configure I'm going to click on settings. Once we've done that what do I actually come over here down into editor, we'll expand that out and I click on an expand general and want to do two things firstly, I want to click on auto import you want to make sure that to both add an ambiguous inputs on the fly is clicked and optimized imports on the fly and then I'll just make your coding a little bit easier as we go through the course, so I'm going to apply that change then next to click on is appearance and make sure that show line numbers is selected, now it is actually showing us a default for me but it's for summaries and it wasn't checked make sure you do check that shown line numbers and once you've done that, you can click on ok and we're actually done at this point, so I'm going to end the video here now and we can move on to the next video and start making use of IntelliJ IDEA.
