![]() ![]() Most of the time the package manager will be perfect, but if you need a specific version, you can check the last part. I will show you how to install Java with the package manager or from the website. Now that you understand all the concepts, we can move to the installation part. ![]() So, basically, you need to install JRE to only run Java applications, or JDK if you want to create them. ![]() It provides a runtime environment to drive Java applications It’s a part of JRE, but you can also download it separately. It includes the compiler, launcher and other required tools It allows you to run Java software on your deviceĪs the name suggests, it’s required for developers It’s the only thing you need if you are not a developer. Here is a list of initials you can find in the “Java world”: Java developers use initials everywhere, and it’s not always easy to understand as a beginner. One last thing I want to clarify is the “JDK” thing. We are almost done with the theory about Java. Sometime you will need to downgrade Java to use a specific version. Most of the time the version from the Raspberry Pi OS repository will be perfect with 99% of your software.Īnd if you have an issue with something, you can check the editor recommendations to see which one you need So, even if you install Java 14 now on your Raspberry Pi, some programs may not work with it, or not be optimized for this version. You should also understand that developers are not following the same rhythm. Here is a summary of the Java version history : VersionĪs always with Debian / Raspberry Pi OS, recent versions are not available in the repository.Ĭurrently, Raspberry Pi OS includes OpenJDK11 (and a few older versions). Java was updated to a new major version almost every 6 months recently. As with most software and programming language, there are regularly new versions available There is no release or sources available for the ARM architecture for the commercial version. On Raspberry Pi, you’ll find only have access to the OpenJDK version. You will probably need more information to understand all the story, but for now just remember that it’s complicated and you have two different products available. You can learn more here if you are interested. OpenJDK is till available under GNU GPL, but the Oracle version is now a commercial product, free for a personal use but a paid service for a commercial use. The short answer is that Java is free and open-source.Ĭurrently, there are two Java versions available : Java SE and OpenJDK. You may also need Java to run some software built with it. So, even if Raspberry Pi is mainly known for Python programming, you can absolutely use it to learn Java or code something with it. ![]() It’s also a strong language with a huge community, so you can find help easily on Stack Overflow for example. It’s working on about any platform without recompilation. What developers like with Java is its portability. You’ll find it almost everywhere, and even it’s an old school language (created in 1995), it’s still very common to use it. Ok, so first point, Java is a popular programming language. Introduction about JavaĪs Java is not as simple as we might think, I start with a quick reminder about different concepts you need to understand before going further. So, the quick answer is simple, but let’s get into a little more detail now.įeel free to use the content table below if you already know the basics. To install Java on another version (Desktop or Lite), the package “openjdk-11-jre” has to be installed with apt or the “Add / Remove software” tool. Java is already installed by default on Raspberry Pi OS Full, so there is nothing to do. I know that many of you have issues with Java on Raspberry Pi, and I will try to help you here with this tutorial And on Linux, you can also add the proprietary topic as Java is now owned by Oracle. Java on Raspberry Pi, and generally on Linux, is a nightmare.Īs on Windows, there are many versions, different packages for users or developers. ![]()
