Updating java mac

On a computer with multiple web browsers, be sure to check the Java version in every browser.I say this because multiple copies of Java can sometimes be installed with different browsers using different copies.

So I wrote a very simple applet (the source code is on the About page) that gets this information from the JRE and displays it in a pink rectangle.Download image J (6MB) as a double-clickable Mac OS X application.Also available bundled with Java 1.8.0_101 (requires OS X 10.8 or later). Download Image J bundled with Java 1.8.0_112 (82MB). Download Image J bundled with 64-bit Java 1.6.0_24 (37MB), bundled with 32-bit Java 1.6.0_24 (44MB) or bundled with 64-bit Java 1.8.0_112 (70MB).Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. To install a lower version of the JRE, first uninstall the current version as described in "Uninstalling the JRE". The one exception is that the system will not replace the current JRE with a lower version.When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time.The Java FX SDK and Runtime are also installed and integrated into the standard JDK directory structure.The Image J Java source consists of 132,000 lines of code in 348 files. Many web pages use Java applets for interactive content such as online games.If Java is working, you will see a pink rectangle above with one line of text that says something like: Java Version 1.8.0_25 from Oracle Corporation or Java Version 1.7.0_67 from Oracle Corporation or Java Version 1.6.0_45 from Sun Microsystems Inc. RUNNING THIS APPLET: Java security has changed quite a lot over the years and running this applet has gotten much more complicated. In the Bizarro world of Oracle, unsigned applets are treated as more dangerous than signed applets. First, unsigned applets run in a restricted Java sandbox whereas signed applets are given unrestricted access to the system.Yes, the sandbox has been buggy and broken, but some security is better than none.
