What version of Java am I using?

NOTE: The latest version of major browsers like Chrome and Firefox does not support NPAPI plugins anymore (except for Flash). This means the some plugins like Java, Microsoft Silverlight and Adobe Acrobat will not work anymore out of the box. The reason is because they make browsing slower, less secure and more likely to crash. In replacement, browser makers have implemented various Web APIs so that websites can do the same things they’ve always done using plugins.

For some applications and Websites to run properly you must have Java installed on your Computer. To visit the official java page, click here. The page automatically detects java installed on your computer and shows the version of Java installed.
