![]() If you don't have the necessary JDK on your computer, select Add SDK | Download JDK. If the JDK is installed on your computer, but not defined in the IDE, select Add SDK | JDK, and specify the path to the JDK home directory (for example, /Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk). If the necessary JDK is already defined in IntelliJ IDEA, select it from the SDK list. If you don't know which distribution to choose, and you don't have specific requirements that instruct you to use one of the existing distributions, use Oracle OpenJDK. 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 is not sufficient for developing Java applications. 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. 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. Go to File | Project Structure | Project Settings | Modules. ![]() In the next dialog, specify the JDK vendor, version, change the installation path if required, and click Download. 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. Go to 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. Go to File | Project Structure | Platform Settings | SDKs. This folder is called an SDK home directory. Java should be available to use within a few minutes.To define an SDK means to let IntelliJ IDEA know in which folder on your computer the necessary SDK version is installed. The Java installation wizard will guide you through the installation step by step. Step 3: Depending on the download option you chose you can extract the downloaded ZIP files or double-click on the executable file. Then you must agree to the license agreement to start and complete the Java download. Step 2: Specify whether you need an “圆4 Compressed Archive” as ZIP file, an “圆4 Installer” as EXE file or an “圆4 MSI Installer” as MSI file. If you want to install the Java Development Kit directly, open the Oracle website for Java downloads and download the installation file. You’ll see the for the current Java download (as of 2022: Java 18) available on the homepage. ![]() Step 1: Go to the Java developer website in the browser. Install Java in Windows 11 as a developer by following these steps: And of course, the Java Runtime Environment (JRE) is also included. The JDK contains handy tools and services such as a Compiler and Interpreter, an editor for Java, API classes, documentation tools, debugger, programs for signing, archiver as well as tools for performance monitoring, applets and the web service importer. Are you interested in running Java in the browser and also using it for programming? Downloading the free Java Development Kit (JDK) from the Java website is advised in this case.
