Java enables you to run applications and games on your Mac




One of the main advantages of Java is that it is cross-platform, which means that it can run on different operating systems, such as Windows, Linux, macOS, etc. This means that if an application or a game is written in Java, you can run it on your Mac without any compatibility issues. Some examples of popular applications and games that are written in Java are Minecraft, Eclipse, NetBeans, LibreOffice, etc.


Java is required by some websites and software




Another reason why you might need Java on your Mac is that some websites and software require it to function properly. For example, some online banking websites use Java to provide security features, some online courses use Java to deliver interactive content, some web conferencing tools use Java to enable audio and video communication, etc. If you don't have Java installed on your Mac, you might not be able to access or use these websites and software.


How to check if you have Java installed on your Mac




Now that you know what Java is and why you might need it, let's see how to check if you have it installed on your Mac. There are three ways to do this:

  • Look for the Java icon in the bottom row of the System Preferences window. If you see it, that means you have Java installed on your Mac.



  • Click on the Java icon to open the Java Control Panel. Here you can see more information about your Java installation, such as the version number, the update status, the security settings, etc.

To uninstall Java on your Mac, follow these steps:
