Tree views of incoming and outgoing references in the heap walker reference view. JProfiler's intuitive GUI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues. Java Development Kit Installation OverviewĪll right so that’s now the housekeeping done.JProfiler is an award-winning all-in-one Java proFILEr.Let’s talk about installing the software we need for this course. So we’re going to be using JDK version 11 in this course. Now JDK stands for the Java Development Kit and it’s the software that is used to create and run Java programs. Now we’re also gonna be using IntelliJ IDEA and that’s much like a word processor but for creating programs. Now on I’m one of the early adopters of IntelliJ. I started using it way back in the early 2000s and it’s a very powerful piece of software packed with lots of features for both beginners and pro developers, but the great thing about it is it’s extremely beginner-friendly as well and there’s a free community edition or paid ultimate edition. You don’t need to spend any money for either of those tools actually and in the upcoming videos in this section of the course, I’m gonna show you how to get the Java Development Kit and IntelliJ IDEA working for Windows, Mac, and also for Linux. Now if you wanna use another IDE, Integrated Development Environment, Eclipse, or something of that nature, you’re welcome to do that. Java Development Kit Installation OverviewĪll right, so it’s time now to install the Java Development Kit. Now if you’re wondering why we’re using Amazon Corretto and why we’re using JDK 11.īut getting back to this course though, there are Amazon Corretto articles, installation articles for the Java Development Kit, for Windows, Mac, and Linux in this section. And in addition, for IntelliJ, there’s also an article for the Windows platform, Mac, and Linux. So read the relevant article for your operating system and once you’ve done that, for both the JDK and IntelliJ IDEA, there’s then a single article for you to go through, irrespective of the operating system you’re running and that gives you some configuration, or an overview of the configuration steps you need to take within IntelliJ, to get it all working together. So make sure you check out that article after you’ve installed both the JDK and IntelliJ IDEA. Let’s get stuck into it in the next part of the article. All right, so it’s time now to install the Java Development Kit. Now we’re going to be using an open-source version of a Java Development Kit, the Open JDK and that’s the creatable version we’re using is created by Amazon and they call it Amazon Corretto. We’ll be using JDK version 11 in this course and not later versions. In a nutshell, version 11 is the LTS, or long-term support version of Java. Now if you’re wondering why we’re using Amazon Corretto and why we’re using JDK 11, I’ve also written some articles, check those out. They give you the reasoning why we’re using Amazon Corretto and why we’re using JDK version 11. Installing IntelliJ Ideaįor this series of articles, we’re going to use an IDE called IntelliJ IDEA. An IDE, or Integrated Development Environment, is the tool that we use to write programs. The main feature is a text editor, that we type our code into. But an IDE also compiles and runs our programs for us. And as you’ll see, it also warns us about errors in our code, before we run it. The IDE we’re going to use is called IntelliJ IDEA, created by a company called JetBrains. There are other IDEs available, and you can use any that you want for this course. If you’ve already got an IDE that you like, and you’re comfortable using, then it’s fine to continue using it. Most modern IDEs provide the same, or very similar, features. If you haven’t used an IDE before, I suggest you use IntelliJ IDEA. That way your environment will work the same way as you’ll see in the videos. In this course, you’re going to download the latest version from the JetBrains website, so I’m going to go to. You can see they’ve got a variety of products. I’m going to close this little popup if it appears for you.
