How to get the mysql list and use it?

Hello everyone, I'm new to programming started two months and today I'm going through a challenge I'll explain to you.

Well, I created a plugin in which the player can buy a certain region, but the information is being registered in a HashMap and every time I restart the server the information basically leaks and everything starts over ..

I learned now the mecher with the basics of mysql and I know how to register information, however now I do not know how to make the plugin I did check the mysql list, Good to get easier to understand this is the system in which verifies the regions : http://pastebin.com/DJsp9nbA

And this place is where it stores information: http://pastebin.com/S8dfuYkU, Sorry for the mess .. But what I wanted to change is how to check this list by taking the information that is registered in my mysql, How do I do this?


Sorry my English because I'm Brazilian!

 

@timtower Yes I know how to store and get information.

 

@timtower Well the plugin I made it takes the HashMap <list> where all the saved information is stored, I get a mysql information at a time I know, but I get several as if it were a <list> I do not know. I do not know if I'm being very accurate, but I want to get all the information that is in the table and return me as a <list>

Catching onEnable and saving not onDisable would it?

 

@timtower Is it basically something like: ?
