They both do the same thing on web sites which need java, but the microsoft version is now obsolete owing to a dispute with Sun Microsystems over who owns the java technology. The Sun version is now the accepted standard and it's free from here:http://www.java.com/...load/manual.jsp
It's called the 'Java Runtime Environment' and that's what you need.
Choose one of the two download options at the top of the list on that web page. The 'Online Installation' will install itself as it's downloading. The 'Offline installation' lets you download the whole thing as a single setup file, which you need to double-click to install just like any other setup file. Choosing that method also means you can save the file if you need to re-install it sometime without having to download it again. When it's installed it will automatically work on Java websites and for Java compiled applications without you having to turn it on.
