Java is a programming language that helps many websites run correctly. When you visit a site that uses Java, it stores some data in a cache on your computer, which helps these sites run faster.

If you're having issues with Java on your Mac or PC, you can clear its cache, which forces it to reload its data. This can clear up bugs and other unusual behavior.

It's worth pointing out, however, that few popular programs or websites rely on Java anymore, and Java is considered by some to be a significant security risk. If you don't have a specific need for Java, you should consider uninstalling it.

Q: I am running Mountain Lion (OS X 10.8) or later and Gatekeeper is blocking an app from launching. What is going on?

A: Gatekeeper, introduced in Mountain Lion (OS X 10.8), is designed to prevent potentially malicious apps from launching. When you attempt to launch an app that doesn't meet certain criteria, Gatekeeper will block the launch. To override this, you can modify Gatekeeper's default settings, or explicitly right/control-click the application and choose Open.

To create a Java application that will launch without interruption under the default Gatekeeper settings, the app must be bundled with a JRE, use Oracle's launcher stub, and be signed with an Apple Developer ID. For more information on creating an app that satisfies these requirements, see Packaging a Java App for Distribution on a Mac.

Q: What happened to the Java Preferences app in Application -> Utilities?

A: The Java Preferences app was part of Apple Java installation and is not used by Oracle Java. Therefore, OS X releases from Apple that do not include Apple Java will not include Java Preferences.

One of the functions of Java Preferences was to set the current version of the JRE. Under Oracle Java, only a single version of the JRE can be installed at a time. For more information, see JRE 7 Installation for Mac OS X.

To access the Java Control Panel, click the Java icon in the System Preferences panel. If the Java icon is not present (under the Other category) in System Preferences, you do not have an Oracle JRE installed.

Q: I have Oracle's version the JRE installed, but it is not listed in Java Preferences.

A: This is correct. The JRE will not show up in the Java Preferences list unless you install the full JDK.

Q: I have Oracle's version of the JRE installed, but when I try to use java from the command line, it does not work.
