Removing Java 8 JDK from Mac
Uninstall Java 8 in a flash on your Mac using Terminal:
Next, remove the Java runtime and additional components with:
This command not only removes JDK but also the browser plugin. Java 8 is now uninstalled from your machine.
Post-removal checks
Post-removal, run these commands in your Terminal to ensure Java 8 is uninstalled:
If Java 8 is still detected, it could mean there are configurations or aliases from past installations. Arrow the target away from JDK 8 by properly setting JAVA_HOME:
List all the JDKs installed on your system using /usr/libexec/java_home -V. This should not list down JDK 8 anymore.
Cleaning up Java-related preferences
If you have Java-related preferences lingering in your system, run the following command to clean them:
Swapping Java versions
If you use multiple Java versions, the Terminal can be your best friend. You can create an alias and use it to switch Java versions easily:
Maintaining an alias not only keeps your development environment neat and tidy, it also enhances security.
Adjustments in your IDE
If you use IntelliJ or any other IDE, update your settings to reflect the changes we made. Make sure it points to the correct JDK version.
If you're using NetBeans or other IDEs that require JDK 6 from Apple, ensure you install it exclusively. This can avoid any possible compatibility issues.
Compatibility and backup
Before removing JDK files, I cannot emphasize enough the importance of backup. Accidents happen, and they cause data loss! So, back up, folks!
Ensure your tools and IDEs are compatible with the new Java versions. Navigating through the storm of JDK versions can be so much easier with compatibility!
Avoiding future troubles
Stay alert and keep an eye on IDE updates about newer Java version support. Regular research on platform compatibility can promise a smooth transition between Java versions.
Reinstallation and updates
If a new JDK needs to be installed, consider the package manager, Homebrew. It makes installation smooth as an eel:
Remember to keep JDK updated for mitigating security vulnerabilities, even while online gaming (I'm talking to you, Minecraft players!).
