548338 Java Tutor Wanted

My 18 year old son is currently studying Java as part of his Diploma in Web Development. He is having problems with this subject and sometimes finds it difficult to continue. He requires a Java programmer, that knows what he is doing that can help him complete assignments. Assignments include (but are not limited to), these features: * Playing music, pausing it, and stopping it. * Reading and writing to a SQL database (I think it's MSSQL, but it may be MYSQL) * Reading and writing to and from an XML flat file database. * Sorting a list of lists by date (ascending and descending, stored in UNIX timestamp) (list of lists, being the output of the XML file) * Searching through a list of lists, and returning the entries. He obviously requires a programmer with: * Good OOP knowledge. * Proper knowledge of interfaces. * Someone who can guide me in the right direction, and explain things to me. If it helps, he works as a web developer, and makes a living by programming in PHP, Javascript, and SQL. Please let me know if you are adequate for this position. We would prefer someone who can briefly check over his assignment and answer questions that he has. You must have a good understanding of the English language and be easy to deal with. We are not sure how many questions he may have for you as he continues with this subject. Payment could be on a pay per incident basis, not sure there. Please advise.
