![]() In IntelliJ IDEA, you can download a JDK package right from the IDE, or you can manually download the necessary JDK distribution and define it in the IDE.įor a manual download, use any available distribution that you like, for example: We recommend that you use one of the OpenJDK builds to avoid potential compliance failures. Before you start developing in Java, download and install a standalone JDK build.ĭue to the changes in the Oracle Java License, you might not have the rights to use Oracle's Java SE for free. The bundled JRE is used for running the IDE itself, and it's not sufficient for developing Java applications. The JRE can be obtained separately from the JDK, but it's not suitable for application development, as it doesn't have essential components such as compilers and debuggers. A JDK is a software package that contains libraries, tools for developing and testing Java applications (development tools), and tools for running applications on the Java platform (Java Runtime Environment - JRE). To develop applications in IntelliJ IDEA, you need a Java SDK (JDK). If you want a module to inherit a project SDK, select the Project SDK option from the Module SDK list. If the necessary SDK is already defined in IntelliJ IDEA, select it from the Module SDK list. Select the module for which you want to set an SDK and click Dependencies. In the next dialog, specify the JDK vendor, version, change the installation path if required, and click Download.įrom the main menu, select File | Project Structure | Project Settings | Modules. Only for JDKs: If you don't have the necessary JDK on your computer, select Add SDK | Download JDK. If the SDK is installed on your computer, but not defined in the IDE, select Add SDK | 'SDK name', and specify the path to the SDK home directory. If the necessary SDK is already defined in IntelliJ IDEA, select it from the SDK list. In the next dialog, specify the JDK vendor, version, change the installation path if required, and click Download.įrom the main menu, select File | Project Structure | Project Settings | Project. Only for JDKs: if you don't have the necessary JDK on your computer, select Download JDK. To add an SDK, click, select the necessary SDK and specify its home directory in the dialog that opens. Configure global SDKsįrom the main menu, select File | Project Structure | Platform Settings | SDKs. ![]() This folder is called an SDK home directory. Red Hat has previously maintained OpenJDK 7, it will continue to support it till June 2020.To define an SDK means to let IntelliJ IDEA know in which folder on your computer the necessary SDK version is installed. Java 8 will be supported till June 2023 while Java 11 will receive updates till October 2024. Red Hat is now taking over the responsibility of maintaining OpenJDK for Java versions 8 and 11. ![]() ![]() The outdated and insecure versions of Java were still being used by IT professionals responsible for the deployment of Java. The company wanted to focus on selling its paid licensing agreements to its enterprise customers. Oracle stopped issuing security updates to Java 8 in January 2019. While developers should be using Java 11, the older Java 8 is the most widely used version of Java on desktops. Java 11 is the first long-term supported (LTS) version of Java. Unlike typical programming languages like C, C++ that receive maintenance updates every few years, Java versions tend to be incremental every six months. The fact that Programmers love Java is no hidden secret and an increasing number of companies are deploying Java in their production environment. The software firm has taken over the reins from Oracle after it ended the commercial support for Java 8 and Oracle JDK 8 implementation of Java SE. Red Hat has come on board to support the OpenJDK 8 and OpenJDK 11.
