Next, we need to configure the PATH environment variable so we can run Java from a command prompt.
There are some reports that this software is potentially malicious or may install other unwanted bundled software. These could be false positives and our users are advised to be careful while installing this software. IcedTea-Web is an open source implementation of Java Web Start.

Step 1 — Installing Java
Oracle JDK comes with the JRE included, so you don’t need to install that separately. Both of these versions are officially recognized by Oracle. Both are also developed by Oracle, but OpenJDK has the addition of community contributions due java se 7 tutorials to its open-source nature. However, starting with Java 11 the two options are now functionally identical as detailed by Oracle. The choice between which to install comes down to choosing the appropriate licensing for your circumstance.
Eclipse Temurin is the open source Java SE build based upon OpenJDK. Temurin is available for a wide range of platforms and Java SE versions. The latest releases recommended for use in production are listed below, and are regularly updated and supported by the Adoptium community.
Test the Oracle JDK 7 Installation #
In 2021, Microsoft started distributing compatible “Microsoft Build of OpenJDK” for Java 11 first then also for Java 17. Their builds support not only Windows, but also Linux and macOS. These binaries are provided primarily for use by implementors of
the Java SE 7 Platform Specification and are recommended for
reference purposes only.
We keep supporting LTS Liberica JDK builds even after the corresponding versions of OpenJDK are no longer supported. Liberica JDK is based on OpenJDK with additional enhancements to boost performance, security and compatibility with different platforms. Another key difference is the reliable support BellSoft provides for their build of JDK, which does not exist for OpenJDK. First we set up an environment variable that will point to our JDK installation. Java SE Development Kit (JDK) is the next Java platform by Sun Microsystems.
Other Linux
Apache Harmony has since been retired, and Google has switched its Harmony components with equivalent ones from OpenJDK. Among the new capabilities in the new version of standard Java are context-specific deserialization filters support, which is a security enhancement, and a preview of pattern matching for switch statements. JDK 17 features everything that has been added since the last LTS release, JDK 11, which arrived three years ago. IntelliSense is a general term for language features, including intelligent code completion (in-context method and variable suggestions) across all your files and for both built-in and third-party modules. VS Code supports code completion and IntelliSense for Java through Language Support for Java™ by Red Hat. It also provides AI-assisted IntelliSense called IntelliCode by putting what you’re most likely to use at the top of your completion list.
To help you set up quickly, we recommend you use the Coding Pack for Java, which is the bundle of VS Code, the Java Development Kit (JDK), and a collection of suggested extensions by Microsoft. The Coding Pack can also be used to fix an existing development environment. In this tutorial you installed multiple versions of Java and learned how to manage them. You can now install software which runs on Java, such as Tomcat, Jetty, Glassfish, Cassandra or Jenkins. One option for installing Java is to use the version packaged with Ubuntu. By default, Ubuntu 22.04 includes Open JDK 11, which is an open-source variant of the JRE and JDK.
The JDK also contains a Java Runtime Environment (JRE) that is able to run compiled Java code. To do this the JRE uses Java libraries and a Java Virtual Machine (JVM) that executes the compiled Java code. In this guide, I’m going to show you exactly how to download and install JDK 1.7 on Windows.
Migration help, container images and package installation guides are available in the documentation section. The officially supported Java platform, first developed at Sun and now stewarded by Oracle, is Java SE. Releases are based on the OpenJDK project, a free and open-source project with an open development model. Other Java implementations exist, however—in part due to Java’s early history as proprietary software. In contrast, some implementations were created to offer some benefits over the standard implementation, often the result of some area of academic or corporate-sponsored research. Many Linux distributions include builds of OpenJDK through the IcedTea project started by Red Hat, which provides a more straightforward build and integration environment.
Java 17
It continues to support various preview features in previous JDK releases; and has also introduced some new features. It has nine new developer features, including a simple web server and another preview of pattern matching for switch. TCK is the Technology Compatibility Kit for Java™, the test suite used by Oracle to ensure compatible implementations of the OpenJDK such as Liberica JDK.
- You will not be able to access
the source code if you are downloading from a country that is not
on this list. - This article will give you an overview of different capabilities of Visual Studio Code for Java developers.
- IBM initially developed OpenJ9 as the proprietary J9[342] but has since relicensed the project and donated it to the Eclipse Foundation.
- The team with 15+ years of Java™ experience is always ready to help you.
- The JRE can be obtained separately from the JDK, but it is not suitable for application development, as it doesn’t have essential components such as compilers and debuggers.
