![]() This command will show us the available packages. ![]() and extract java into the '/opt/jdk' directory: sudo tar -zxf jdk-8u5-linux-圆4.tar.gz -C /opt/jdk. Create a directory for your JDK installation: sudo mkdir /opt/jdk. Step 2: Installing from Ubuntu repository The /opt directory is reserved for all the software and add-on packages that are not part of the default installation. sudo apt update & sudo apt upgrade -yĭepending on how recently you have run the updates, it may take a few minutes or a few seconds.

OpenJDK 17 Installation process Step 1: Update your Ubuntuįor this article, we are using one of our cheap, affordable and fast ServerLynx Linux KVM VPS machines. Deprecation of RMI Activation System: The Remote Method Invocation (RMI) Activation System has been deprecated in OpenJDK 17, reflecting the decreasing usage of this technology in modern Java applications.This enhances code maintainability and security. Sealed Classes: OpenJDK 17 added the ability to declare classes as “sealed,” which restricts which other classes or interfaces can extend or implement them.Deprecation of Applet API: The Applet API, which was widely used for web applets in the past, has been deprecated in OpenJDK 17, marking its gradual phasing out in favor of modern web technologies.It’s especially useful for tasks like working with machine learning libraries or low-level system interactions. Foreign Function and Memory API (Incubator): This feature allows Java code to interoperate with native code more efficiently.This can help prevent unintended dependencies on internal APIs. Strong Encapsulation of Internal APIs: OpenJDK 17 continued the process of encapsulating internal APIs, making the Java platform more modular and secure.This simplifies code by allowing developers to combine type checking and casting in a single operation. Pattern Matching for instanceof: OpenJDK 17 introduced pattern matching for the instanceof operator.Cloud-Native Development: OpenJDK 17 is suitable for developing cloud-native applications and microservices, benefiting from its performance enhancements and support for modern containerization technologies.Mobile Development: Java continues to be a popular choice for Android app development, and OpenJDK 17 can be used for building Android apps, particularly with the adoption of Java 8 features in the Android ecosystem.Its LTS status ensures stability for mission-critical applications. Server-Side Applications: OpenJDK 17 is well-suited for building server-side applications, such as web servers, microservices, and enterprise-level systems.In this article, we will teach you how to install OpenJDK 17 on Ubuntu 20.04 or 22.04 version. The latest OpenJDK LTS version is 21, but version 17 is still regularly maintained and it’s security support ends in 6 years, meaning that many things still rely on it and require it since end of life is not even near. OpenJDK, the open-source implementation of the Java Platform, Standard Edition (Java SE), has become the preferred choice for many developers. Java, with its robust cross-platform capabilities and a thriving ecosystem of applications, remains a fundamental technology for developers and organizations alike.Īs the Java ecosystem evolves, staying up to date with the latest Java Development Kit (JDK) versions is crucial for taking advantage of new features, improvements, and security enhancements. It is really so simple to install OpenJDK 9 on Ubuntu and this tutorial covers the ground on the same process.īefore you begin with the process, make sure you update your Ubuntu operating system by making use of the following command.How to install OpenJDK 17 on Ubuntu 20.04 or 22.04 JDK is a collection of tools required to develop, debug, package Java applications. Programmers use Java Development Kit or JDK to compile and run Java programs. That is why it is so popular and billions of devices have Java installed. I tried to uninstall each one, but I failed for the same reason. So I want to uninstall them all, but I cant erase them. Im using wsl2 ubuntu 20.04.5 I accidentally installed too many openjdk. So Java can be compiled once and run everywhere. I just installed Ubuntu, and this is my first time working in a Linux environment. ![]() But the Java byte code is platform independent. JVM on Linux is different than JVM on Mac OS or Windows and so on. That is, JVM on Windows is different than JVM on Linux or Mac OS. As a computer can only understand machine language, it is the JVM that is responsible for running a Java program. Then a Java Virtual Machine or JVM is used to translate the Java byte code into machine language. It compiles to Java byte code using the Java compiler. But it doesn’ t compile Java code to machine language directly. Java is a high level programming language.
