Installing Java 17 on Raspberry Pi


Introduction

This guide will show you how to enable the already available Java 17 JDK versions on the Raspberry Pi. The OpenJDK is essential for running applications like Ignition Edge on your Pi. OpenJDK is a development environment for building applications, applets, and components using the Java programming language.

Steps to Install Java 17

1. Open Add/Remove Software:

  • Go to the top left corner and click the home logo with the raspberry icon.

  • Navigate to Preferences and select "Add/Remove Software."

The Raspberry Menu expanded with the Preferences menu also expanded and the "Add / Remove Software" option highlighted.

2. Search for OpenJDK

  • In the search bar, type OpenJDK and press Enter.

  • Scroll through the list to find the relevant packages.

The software search menu with "openJDK" in the search bar and the following softwares highlighted: OpenJDK Development Kit (JDK), OpenJDK Development Kit (JDK) (headless), OpenJDK Java Runtime, using Hotspot JIT, and OpenJDK Java Runtime, using Hotspot JIT (headless).

3. Select the following packages:

  • OpenJDK Development Kit (JDK)

  • OpenJDK Development Kit (JDK) (headless)

  • OpenJDK Java Runtime, using Hotspot JIT

  • OpenJDK Java Runtime, using Hotspot JIT (headless)


4. Install the Selected Packages:

  • Select all four packages mentioned above.

  • Click "Apply" to install the selected packages. You only need to do this once if all four packages are selected.

5. Verify Installation:

  • Open a terminal window.

  • Run the following command to verify the installation:
        java -version.

  • You should see the version information for Java 17, confirming the installation was successful.

Additional Information

  • OpenJDK Development Kit (JDK):

    • This package provides the full Java development environment, including the compiler and other tools needed to develop Java applications.

  • OpenJDK Development Kit (JDK) (headless):

    • This package is a headless version of the JDK, suitable for running applications without a graphical user interface.

  • OpenJDK Java Runtime, using Hotspot Jit:

    • This package includes the Java runtime environment with the Hotspot Just-In-Time compiler for optimized performance.

  • OpenJDK Java Runtime, using Hotspot Jit (headless):

    • This is the headless version of the Java runtime environment, optimized for server environments without a GUI.

By following these steps, you will have Java 17 installed on your Raspberry Pi, enabling you to run Ignition Edge and other Java-based applications. This setup ensures that you have the necessary development and runtime environments for building and running Java applications on your Raspberry Pi.
