To install the Java Development Kit (JDK) on your system, you can follow these general steps. Please note that the specific instructions may vary depending on your operating system.

1. Visit the Oracle JDK or OpenJDK Website:

First, decide whether you want to install the Oracle JDK (a commercial version with long-term support) or the OpenJDK (an open-source implementation of the Java Platform).

• For Oracle JDK: Visit the Oracle JDK download page (https://www.oracle.com/java/technologies/javase-downloads.html) and download the appropriate version for your operating system. Accept the terms and conditions, and proceed with the download.

• For OpenJDK: Visit the AdoptOpenJDK website (https://adoptopenjdk.net/) or the official OpenJDK website (https://jdk.java.net/) and download the desired version. OpenJDK is available for various platforms, including Windows, macOS, and Linux.

2. Installation Steps (Windows, macOS, Linux):

The installation process may vary depending on your operating system. Here are instructions for the most common ones:

• Windows:

  • For Oracle JDK: Run the downloaded installer and follow the on-screen instructions.
  • For OpenJDK: You can use Windows package managers like Chocolatey or scoop to install OpenJDK. Alternatively, you can manually extract the downloaded archive and set the PATH environment variable to include the JDK’s bin directory.

• macOS:

  • For Oracle JDK: Run the downloaded DMG file and follow the installation steps.
  • For OpenJDK: macOS users can use package managers like Homebrew (brew install openjdk@11) to install OpenJDK.

• Linux:

  • For Oracle JDK: Run the downloaded installer or follow the instructions for your package manager (e.g., DEB or RPM) if available.
  • For OpenJDK: Use your package manager (e.g., apt, yum, or dnf) to install OpenJDK. For example, on Ubuntu, you can run sudo apt install openjdk-11-jdk.

3. Verify Installation:

After the installation is complete, you can verify it by opening a terminal or command prompt and running the following command:

This command will display the installed Java version. Additionally, you can check the JDK version with:

Both commands should provide information about the installed JDK version.
