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.

In this tutorial, you learned how to install Java Runtime Environment ( JRE) and the Java Developer Kit ( JDK) on Ubuntu 20.04 and Ubuntu 18.04.To define an SDK means to let IntelliJ IDEA know in which folder on your computer the necessary SDK version is installed. You will get the following output: /usr/lib/jvm/java-11-openjdk-amd64

Verify that the environment variable is set: $ echo $JAVA_HOME Save the file and reload the file to apply the changes to your current session: $ source /etc/environment Then open /etc/environment file using nano text editor: $ sudo nano /etc/environmentĪdd the following line at the end of the file, make sure to replace the location of your Java installation path. You will get the following output: /usr/lib/jvm/java-11-openjdk-amd64/bin/java To set the JAVA_HOME environment variable, first, discover where Java is installed by running the following command. Most of the Java-based software programs use the JAVA_HOME environment variable to discover the Java installation location. Setting the JAVA_HOME Environment Variable in Ubuntu

You will get the following output: javac 11.0.10 $ sudo apt install default-jdkĪfter installation, verify the JDK installation by checking the version as shown. To install the JDK, run the following command. Once JRE installed, you might also need the JDK ( Java Development Kit) in order to compile and run a Java-based application. OpenJDK 64-Bit Server VM (build 11.0.10+9-Ubuntu-0ubuntu1.20.04, mixed mode, sharing) OpenJDK Runtime Environment (build 11.0.10+9-Ubuntu-0ubuntu1.20.04) You will get the following output: openjdk version '11.0.10' Once Java installed, you can verify the installation with: $ java -version Now run the following command to install the default OpenJDK 11, which will provide Java Runtime Environment ( JRE). Sudo apt install openjdk-8-jre-headless # version 8u282-b08-0ubuntu1~20.04 Sudo apt install default-jre # version 2:1.11-72 Command 'java' not found, but can be installed with: If Java is not currently installed, you will get the following output.
