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?

Isn't it funny how there's always time and money enough to do it WRONG?

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.
