1 00:00:05,280 --> 00:00:12,540 For this course, we're going to use an IDE called IntelliJ IDEA. An IDE, or Integrated Development 2 00:00:12,540 --> 00:00:15,510 Environment, is the tool that we use to write programs. 3 00:00:15,630 --> 00:00:23,430 The main feature is a text editor, that we type our code into. But an IDE also compiles and runs our programs for us. 4 00:00:23,910 --> 00:00:27,820 And as you'll see, it also warns us about errors in our code, before we run it. 5 00:00:28,260 --> 00:00:33,310 The IDE we're going to use is called IntelliJ IDEA, created by a company called JetBrains. 6 00:00:34,050 --> 00:00:38,070 There are other IDEs available, and you can use any that you want for this course. 7 00:00:38,430 --> 00:00:43,670 If you've already got an IDE that you like, and you're comfortable using, then it's fine to continue using it. 8 00:00:44,070 --> 00:00:46,980 Most modern IDEs provide the same, or very similar, features. 9 00:00:47,550 --> 00:00:51,960 If you haven't used an IDE before, I suggest you use IntelliJ IDEA. 10 00:00:52,560 --> 00:00:56,550 That way your environment will work the same way as you'll see in the videos. 11 00:00:56,550 --> 00:01:02,670 In this course, you're going to download the latest version from the JetBrains website, so I'm going to go to jetbrains.com. 12 00:01:07,140 --> 00:01:13,350 Come over here to Tools. You can see they've got a variety of products. The one we want is IntelliJ IDEA. click on that. 13 00:01:15,280 --> 00:01:17,550 I'm going to close this little popup, if it appears for you. 14 00:01:17,940 --> 00:01:18,840 Click on download. 15 00:01:20,520 --> 00:01:24,780 So you can see over here to the right, there's a Community Edition. That's the one we're going to download. 16 00:01:24,960 --> 00:01:30,020 The Community Edition is free, so I'm going to click on download. The Ultimate Edition has some extra features, 17 00:01:30,020 --> 00:01:33,780 but you'll have to pay for it. You won't need those extra features for this course. 18 00:01:34,200 --> 00:01:40,000 So we'll leave it to download, and you can see it downloading, in the bottom left hand corner of the screen. 19 00:01:42,400 --> 00:01:44,830 OK, I'm going to open the file, now that's been downloaded. 20 00:01:47,570 --> 00:01:48,720 We're going to close down the browser. 21 00:01:48,750 --> 00:01:55,550 We no longer need that. We're going to select Yes to this option, Do want to allow this app to make changes to your device. 22 00:01:56,690 --> 00:01:57,950 We're going to click on next. 23 00:01:59,370 --> 00:02:03,030 I'm going to leave the destination folder unchanged, and click on next. 24 00:02:04,210 --> 00:02:10,930 On the screen for the installation options, you need to know whether you're running a 64 bit or 32 bit version of Windows. 25 00:02:11,900 --> 00:02:13,720 I showed you how to check that, earlier in the course. 26 00:02:13,840 --> 00:02:15,730 As a recap, come down here. 27 00:02:15,730 --> 00:02:17,830 You can either type 32, or type about, 28 00:02:18,790 --> 00:02:24,970 To get to you about your PC page. Either will get you there. And scrolling down here to system type. 29 00:02:24,970 --> 00:02:29,620 If it says 64 bit operating system, as mine does, then you have a 64 bit version of Windows. 30 00:02:29,620 --> 00:02:31,660 Otherwise you're running a 32 bit version. 31 00:02:32,050 --> 00:02:35,140 And this will be important as we swing back, to our installer screen. 32 00:02:35,140 --> 00:02:40,090 So make a note of which version you're running. And also ignore the x64-based processor. 33 00:02:40,300 --> 00:02:42,550 It's the operating system that we're interested in here. 34 00:02:42,970 --> 00:02:43,980 So closing it down. 35 00:02:44,260 --> 00:02:50,460 So back in the installer, tick the appropriate launcher for your system, in the create desktop shortcut section. 36 00:02:50,890 --> 00:02:58,350 You want a 32 bit launcher on a 32 bit version of Windows, and a 64 bit launcher on a 64 bit version of Windows. 37 00:02:58,690 --> 00:03:03,880 I'm going to click the 64 bit launcher, because my Windows was 64 bit, as we saw. 38 00:03:04,030 --> 00:03:06,430 But make sure you click the right one for your system. 39 00:03:07,370 --> 00:03:14,930 Additionally, and only 32 bit Systems, check the Download and install 32-bit JetBrains runtime box. 40 00:03:15,140 --> 00:03:19,640 I don't need to do that, because I'm running a 64 bit version. Leave everything else un-ticked. 41 00:03:19,670 --> 00:03:25,430 The other options are more for convenience, and aren't essential. Click on Next, then click on Install. 42 00:03:27,570 --> 00:03:29,700 IntelliJ will now install, which will take a few moments. 43 00:03:33,940 --> 00:03:39,370 All right, so once it's installed, tick the box to Run IntelliJ IDEA Community Edition, and click finish. 44 00:03:42,580 --> 00:03:47,350 You may or may not see this pop up. If you do see it, this is a standard privacy policy type agreement. 45 00:03:48,390 --> 00:03:52,290 Confirm that you've read it, and obviously you want to read that at some point. Click on Continue. 46 00:03:53,250 --> 00:03:54,630 The screen may pop up as well. 47 00:03:55,050 --> 00:03:59,130 You can always change the behavior, you can see the link there, in settings, if you need to change it at a later time. 48 00:03:59,480 --> 00:04:01,020 I normally select Don't send. 49 00:04:04,090 --> 00:04:09,130 Now, you may or may not be prompted also to import settings from your previous installation. I wasn't 50 00:04:09,130 --> 00:04:12,340 prompted. But most students will be installing this for the first time. 51 00:04:12,550 --> 00:04:16,079 So make sure, if you are prompted for that, to select Do not import settings. 52 00:04:16,089 --> 00:04:18,670 And again, you saw that I wasn't actually prompted there for that. 53 00:04:19,540 --> 00:04:23,990 At this point, we're now at the welcome screen. Now this new version, which was released at the beginning 54 00:04:23,990 --> 00:04:29,570 of December 2020, has a different Welcome screen to the earlier versions of Intellij IDEA. 55 00:04:30,320 --> 00:04:34,690 Most of the time you'll be working with Projects selected, and you can see that in the left hand side. 56 00:04:35,090 --> 00:04:37,910 This is where you create new projects and open your existing ones. 57 00:04:38,450 --> 00:04:43,100 We'll be creating our first project in the next section of the course, but there's a couple more things 58 00:04:43,100 --> 00:04:44,570 we should configure before we do that. 59 00:04:45,330 --> 00:04:49,250 The one thing you may not like is the dark background that IntelliJ uses. 60 00:04:49,430 --> 00:04:54,100 And that's okay, because you can change it. You can click on Customize, over here to the left, and we 61 00:04:54,110 --> 00:04:56,030 get some options that control the display. 62 00:04:56,570 --> 00:05:01,790 The default color theme has a dark background. JetBrains calls the theme Darcula. 63 00:05:01,970 --> 00:05:04,730 Many programmers prefer that, and it's now the default. 64 00:05:05,150 --> 00:05:09,720 But if you prefer a light background, click the dropdown and choose one of the lighter themes. 65 00:05:10,070 --> 00:05:15,110 Personally, I also prefer a dark background, but it doesn't show up that well on video, so I'm going 66 00:05:15,110 --> 00:05:16,970 to change mine to IntelliJ Light. 67 00:05:17,960 --> 00:05:23,230 If you've set your operating system to use a light or dark theme, you can check the Sync with OS box. 68 00:05:23,530 --> 00:05:26,950 That works on Windows and Mac, but doesn't, unfortunately, work on Linux. 69 00:05:27,560 --> 00:05:31,180 If you want to change the font size that IntelliJ uses, you can do that from here, too. 70 00:05:31,630 --> 00:05:36,190 You can also adjust the colors for red and green colorblindness, if that's something you'd find useful. 71 00:05:36,520 --> 00:05:36,790 All right. 72 00:05:36,800 --> 00:05:41,030 So at this point, we're now done. We've now successful installed IntelliJ IDEA. 73 00:05:41,470 --> 00:05:45,550 So now that you've done that, we do have a few minor configurations that we need to finish up. 74 00:05:46,120 --> 00:05:51,370 Specifically, what we need to do is configure it for the Software Development Kit, so that we can start 75 00:05:51,370 --> 00:05:55,110 creating programs in this course. But we're going to do that in a separate video. 76 00:05:55,900 --> 00:05:58,360 I'll end the video now and we'll see you in the next video. 77 00:05:58,630 --> 00:06:02,380 Where we start making a few other changes, to configure IntelliJ IDEA. 78 00:06:03,110 --> 00:06:05,710 Now skip over the videos for the other operating systems. 79 00:06:05,890 --> 00:06:08,980 So if you're using windows, you can now skip the videos for Mac or Linux. 80 00:06:09,280 --> 00:06:16,120 But make sure you do watch the last video in this section, the one called Configuring IntelliJ IDEA for Windows, Mac and Linux. 81 00:06:16,420 --> 00:06:20,140 This is where we'll set up IntelliJ to work with our chosen language code. 82 00:06:20,530 --> 00:06:25,050 Now, the steps are the same for all three operating systems, and I've covered them all in the same video. 83 00:06:25,390 --> 00:06:27,670 So it's very important that you *don't* skip that video. 84 00:06:27,880 --> 00:06:32,740 You *must* follow the steps in the Configuring IntelliJ IDEA for Windows, Mac and Linux. 85 00:06:32,920 --> 00:06:34,750 So I'll see you in that video.
