Use Terminal To Uninstall JDK

Removing Java from your Mac using the Terminal is a bit more involved than other means. If you’re a tech-savvy person, then this way will give you the most peace of mind, knowing that every Java file on your system will be removed. If you are not tech-savvy, then you may want to try one of the easier options. Open the Terminal application by typing “terminal” in Spotlight or find it in the Applications folder under Utilities.
  1. Input the command sudo rm -rf/Library/Java/JavaVirtualMachines/{put version number here} to remove the JavaDevelopmentKit directory associated with OpenJDK.
  2. Enter your admin password when prompted, and enter y for yes to proceed with the uninstallation process.
  3. Then, type in sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin and press enter. This will delete the Java plugin folder.
  4. After that, type in sudo rm -rf ~/Library/Application\ Support/Oracle/Java and press enter. This will delete any Java-related files from your home library.
  5. Next, type in sudo rm -rf /System/Library/Frameworks/JavaVM.framework and press enter. This will remove the framework for running Java applications.
  6. Finally, type in sudo rm -rf /usr/bin/java to remove the executable file associated with running Java applications. Press enter to complete the process of removing Java from your system.

Using The Libary Command

Removing OpenJDK from your Mac using the Library command is a little bit easier than using Terminal, but still requires a bit of technical know-how:
  1. Open a Finder window and click on the Go menu at the top of your screen.
  2. Select Go to Folder from this menu and type in /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/ – this will open up a new folder with several files inside it.
  3. Now, select all of these files and delete them by dragging them into the Trash bin.
  4. After that, navigate back to your ~/Library/Application Support folder and delete any files related to Java (e.g., jre, jdk).
  5. Finally, navigate to /System/Library/Frameworks/JavaVM.framework and delete any remaining files associated with Java – after doing so, Java should be completely removed from your system.

Use The Java Installation File

Uninstalling OpenJDK on a Mac using the Installation File is an effective way to get rid of any unwanted versions. Here’s what you need to do:
  1. Open Finder, then open the Applications folder. Select the installable OpenJDK application file.
  2. Right-click on it and select the Move to Trash option from the drop-down menu to delete it from your computer.
  3. Enter your admin password when prompted, and enter y for yes to move forward with this process.
  4. After that, open ~/Library/Application Support/Oracle/Java and delete any remaining files related to Java – once complete, you should have successfully removed the application from your Mac.

Using Third-Party Applications

For those who are not so tech-savvy, don’t worry. There are a few third-party solutions you can use for this problem. Here are the two best solutions you can find:
