These two are often confused so I'll explain the difference and what they do. Javascript is built into every browser and is standardized. This allows a web page to execute operations on your computer. Simple example here is inserting smilies into posts. As another example the fuel comparison calculator, when you change a value the browser executes a command to recalculate the values in the last column. Obviously Javascript has great value and it will be pretty difficult to find a site that hasn't implemented it's use in some fashion.
Java on the other hand is something completely different. This is a third party proprietary application similar to Adobe's flash, it may even be used for applications other than a web browser. Like Flash it's on the way out the door. It's been a very long time since this was widely used. If you have Java installed you likely do not need it, it's very unlikely any websites or application you use require it. Since it poses a potential security risk the best thing to do is uninstall it from Windows. If for whatever reason you find that you need Java it can always be reinstalled.
