Java developers

what do i have to import to make my Hash object work in java?

Hash h2 = new Hash();

cannot resolve symbol

or another way i can get objects (integers) to hash to a table instead of adding them to the table myself (no function)?

A silly question, probably...

I know that you can add values to an array at instantiation

String[] alphabet = { "A", "B", "C", "D", ..., "X", "Y", "Z" }

I was wondering if you could do the same for an ArrayList?
