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. See Installing the JRE on macOS. If you have not yet installed Apple's Java macOS 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in. The best approach to install Java on the Mac is to get the latest version of Java JRE directly from Oracle. This is fairly straight forward and you can either initiate the process from the terminal application in macOS or by going directly to the Java download page on Oracles website.

You can find Java version on Mac without running a Java applet in your web browser. Fortunately, there are a variety of methods to find the Java version on Mac. Below is a description of some of those methods. Also see Java Support in Safari 12.
Using Command Line in Terminal
Terminal is a program included with macOS that provides command line access to the operating system. Terminal is located under Applications folder -> Utilities folder. To find the Java version using command line, launch the Terminal application. Type or copy/paste the following line into the Terminal window:
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
The Java version will display as output in the Terminal window, and will look similar to the output below:
java version '1.8.0_40'
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
In this case, Java 8 Update 40 is the Java version installed on this Mac.
Using the Java Control Panel
You may find Java version on Mac using the Java Control Panel instead. For information about locating the Java Control Panel, please see the Where is the Mac Java Control Panel located article. Once you have launched the Java Control Panel, click the General tab.
In the section entitled About, click the About… button. A new About Java window will launch. Java version information will display within the window.
In this case, Java 8 Update 40 is the Java version installed on this Mac.
Using the Online Test Java Page
You may also test your Java online to determine which version of Java is installed on your Mac. To test Java on your Mac, visit the Test Java page provided by Oracle on its Java.comweb site. This utility will not only check your current Java installation, but will also remove old Java versions from your computer that may pose a security threat to your system. If your Java is working correctly, and no out-of-date Java versions are found, you will see the following notification accompanied by information about your Java installation and your computer:
As it states in the Verified Java Version web page, Java 8 Update 40 is installed on this Mac. If your Java is not working properly, the Test Java page displays additional configuration options that you may need to check, as well as download and installation instructions if needed.

Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. It is now an optional install that you must select.
Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.
If the Java runtime is not installed, some issues that are known to occur include -
- Failure to launch.
- Install Java runtime prompts when you attempt to use the applications.
- Applications hang or quit.
