Java is installed as a browser plug-in, unless you have installed a full version of it for programming in java script language using such consoles as NetBeans.
The java interface installs into the application data folder which is by default a hidden folder, this is why you can not see it.
Here's a link to the Java web site and the download link for Windows OSes. http://www.java.com/en/download/inc/windows_new_ie.jsp
