item ID numbers

[Nicholas Lefebvre]

I need to make a program that can aoutomaticaly create and asign a ID number to a new item but the ID number can not be repeated once. How would i do that the rest of the program is working i just need to genereate it.

Depending on your id requirement, you can consider AtomicInteger, AtomicLong or UUID

My advice: Use a database.

Chances are that your Item will have to be stored somewhere anyway, so why not use the place where you're going to store it?

I dont know how to start setting up the database but i do know how to start the data base is access but MySQL and that i dont know.So could you tell me the steps involved.

create a java class containing the jdbc mysql class objects there you define your database name and password. but before that you need to download the plugin and extract it into your jar file library.
