First correction in the code I like to make is we usually wont create objects of type ArrayList but only List
Second I dont think 1005 is a valid name ....
Ooooooooh enough of finding the mistakes Sorry dude
About your question what I understood you need is the little bit complicated In fact I dont know the way to do that .. ie
"the variable name will be dynamic "
Actually do you really need something like that , From my three years of programming I was happy with the 'static' variables
Cant you tell me a situation you will need this
