However, you can still obtain OpenJDK 11, which is functionally equivalent to Oracle JDK 11 and is available as an open-source alternative. Here’s how you can download and install OpenJDK 11:

1. OpenJDK 11 (Adoptium):

   • Visit the Adoptium website: https://adoptium.net/
   • On the home page, you will find the “Latest Release” section.
   • Under “OpenJDK 11 (LTS)”, select your preferred version (e.g., HotSpot, OpenJ9).
   • Choose your platform (e.g., Windows, macOS, Linux).
   • Click the “Latest Release” button for the selected configuration to start the download.
   • Once the download is complete, run the installer and follow the installation instructions.

2. OpenJDK 11 (Alternative Sources):

   • You can also obtain OpenJDK 11 from other sources such as AdoptOpenJDK (which has been renamed to Adoptium) and distributions like Amazon Corretto and Red Hat OpenJDK.
   • Visit the respective websites for these distributions to download OpenJDK 11 according to your platform and requirements.

3. Package Managers:

   • On some Linux distributions, you can use package managers like apt, yum, or brew to install OpenJDK 11. For example, on Ubuntu, you can use the following command:
     arduinoCopy code

     sudo apt-get install openjdk-11-jdk

After you have successfully installed OpenJDK 11, you can set up environment variables, such as JAVA_HOME and update your system’s PATH to make it the default Java version if needed.
