Here are step-by-step instructions, created by chatGPT but not tested by PDS, for installing OpenJDK 11 on Linux, macOS, and Windows:

1. Installing OpenJDK 11 on Linux

Debian/Ubuntu-Based Systems:

1. Update your package list:

   sudo apt update

2. Install OpenJDK 11:

   sudo apt install openjdk-11-jdk

3. Verify the installation:

   java -version

   This command should display OpenJDK version 11.

CentOS/RHEL-Based Systems:

1. Install the EPEL repository (if not already installed):

   sudo yum install epel-release

2. Install OpenJDK 11:

   sudo yum install java-11-openjdk-devel

3. Verify the installation:

   java -version

Fedora:

1. Install OpenJDK 11:

   sudo dnf install java-11-openjdk-devel

2. Verify the installation:

   java -version

2. Installing OpenJDK 11 on macOS

1. Install Homebrew (if not already installed):
   Open a terminal and paste the following command to install Homebrew:

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Update Homebrew:

   brew update

3. Install OpenJDK 11:

   brew install openjdk@11

4. Add OpenJDK 11 to your PATH:

   echo 'export PATH="/usr/local/opt/openjdk@11/bin:$PATH"' >> ~/.bash_profile
   source ~/.bash_profile

5. Verify the installation:

   java -version

3. Installing OpenJDK 11 on Windows

1. Download OpenJDK 11:

   • Visit the Adoptium website or the Oracle website and download the OpenJDK 11 installer for Windows.

2. Run the Installer:

   • Double-click the downloaded .msi file to run the installer.
   • Follow the installation instructions and accept the default options.

3. Set the JAVA_HOME Environment Variable:

   • Go to Control Panel > System and Security > System > Advanced system settings.
   • Click on Environment Variables.
   • Under System variables, click New and enter JAVA_HOME as the variable name and the path to your JDK installation (e.g., C:\Program Files\OpenJDK\jdk-11) as the variable value.
   • Find the Path variable in the list of system variables, select it, and click Edit. Add %JAVA_HOME%\bin to the list of paths.

4. Verify the installation:

   • Open a Command Prompt and type:

     java -version

   • This should display OpenJDK version 11.

5. Troubleshooting:

• The 32-bit JRE is the default on Windows, and even the online installer for Windows on the Java Download All Operating Systems page only installs the 32-bit JRE. If you see an error like that described under this common error, you have the wrong JRE installed.
• If the either of these commands fail, it indicates Java is not installed or the version is not at least 1.9. Consult the local system administrator for installation of this software. For the do-it-yourself crowd, the Java software can be downloaded from the Java Download page.

These steps should help you install OpenJDK 11 on your respective operating system. Let me know if you need any further assistance!
