Oracle's newly released Java 7 runtime is relatively painless to install and uninstall.

Java used to be deeply embedded in OS X, but in recent versions of the OS it's an optional install. Here is how to check to see if it is installed, and how to disable or remove it.

You can check which Java version is on your Mac to see if you have the most up-to-date Java running, or you can check on the Java website.

Do you have Java installed on your Mac? Well, you might want to rethink that decision, thanks to adware bundled with the latest Mac OS X installer from Oracle.
