Java is completely diffrent than JavaScript and jquery is simply a javascript library so when u use jquery u use actually JavaScript

Answer 4

ValentinHacker is right. I'd add that JS (javascript) is a (usually, though you could use a js shell) client side scripting language mostly used in web pages.

Java is another programming language and can be used with jsp (Java EE) to have web capabilities, but it will be server side (only able to modify data once it is sent to the server).

Java used to have the capability to make apps built in a page (applets), but applets functionality are getting removed from modern browsers and it will probably die off soon.
