English In this video, I'm going to go ahead and download and install the JDK which is the Java development kit which contains the software to be able to run programs in this course. Now if you're running on a Mac or a Linux machine, you want to check out a specific video that we've created in this section of the course for those operating systems, the reason is the steps are slightly different for each platform. So this is the windows video. So, if you are on Windows going to start by going to java.oracle.com it'll bring you to a page from Oracle which are now the owners of the Java product. When I come over here and the technologies and click on Java SE and once that page loads, come over here and click on downloads and finally once we get to that page, there's this little icon here this little image and it will say Java platform JDK and a number here. Now it's highly likely that this number will change in the future because Oracle release at regular intervals updates to the Java development kit, so if you're going to later number then that's fine, just click on the graphic there and that will take you to the download page, when we can actually download the software. Now what we need to do is determine whether your computer is of 32 or is running a 32 or 64-bit version of Windows, the reason for that is that there's two versions of the JDK available, you can see here windows x86 and windows x64 so what that means is windows x86 is for computers running 32-bit version of Windows and Windows x64 is for 64-bit version of Windows, so to find out which version you're running on your computer, you basically want to get into control panel or if I'm Windows 10 it's settings, so I'm going to come down here, click on the start icon, click on settings, once you get into your control panel or in my case windows settings click on system and then there's an option down here for about that's certainly what it is for Windows 10, it might be slightly different for older versions of Windows, but there's an option on all versions of Windows to tell you what version of Windows you're running and here on the system type, you can see that it's a 64-bit operating system so ignore this part to the right where it says x64 based processor, because it is possible confusingly to have a 64-bit processor but to be running a 32-bit version of the Windows operating system. So the bit the important bit here is to the left when it's a 64-bit operating system that tells me there that I'm running a 64-bit version of the operating system and I can now choose my download the only other option that would come up would be a 32-bit version and once you know that, you can close that screen down you come back to the page that we loaded previously and choose the relevant version. Now before that allow you to download, you need to click on accept license agreement this little radio button that you saw me click and now I need to choose the version, so a 32-bit version that would be the windows x86 version in my case 64-bit, 64-bit version or 64-bit edition of Windows, so I'm going to click on that little option there to me, so you'll choose which other one is appropriate and I'm going to click on run to let Windows run this, so that we can go ahead and install it. So I'll just fast-forward this while it continues and completes the download. Okay so I've gone ahead and the download is finished and it started because I selected it to run now if you didn't select run, you might have to double click the downloaded program to start it but in any event it should start, I'm going to close in the browser because we no longer need it and you get to a process like this an installation process that we can actually go through. So I can come through here now, I can click on next now you may actually need to know this later in the course, so just keep to the back your mind or perhaps write down the area or the path that this software has been installed in, you can see in my case it's going to be installed in c colon backslash Program Files backslash Java and then this number will relate to the version that you've downloaded, the important part is Program Files slash Java so you may need may or may not need that later in the course but have a make a mental note of that or write it down so you know. Click on next, we don't need to change any options there, we'll let it do its thing and install, next thing it does is install JDK but it also wants to install the JRE, JRE stands for Java Runtime Edition and you do need to have both things on your computer in order to be able to use Java, so we're going to just click on next, noting that that directory the C colon backslash program files slash Java so it's actually putting it in a different sub folder and again you may need that later in the course, click on next and let it do its thing again. Alright, so at this point so you can see that it's come up and said the java SE development kit 8 update and then the number has been successfully installed, so we're actually done so and click on close. I'm going to finish the video here let's move on to the next one.
