need help

[manamino]

hi, I'm new to xml, actually I'm taking a course in xml and I should choose a certain project related to xml.
I want to ask about xml and java
the things that I know about java is some classes ( I made a program of bouncing ball in java and changed some java game programs). but I need to know how to use java in databases and how to relate it to xml
Is it too dificult or I can learn it knowing that I'm ready to learn and already I'm learning xml.
If anyone wants to help me please send me links to some websites where it is simple to learn java .
Also if any one can give me an example of a certain project that can be done easily using java and xml u'll be more than welcome
