How to add , remove and retrive a value from array or arraylist?

Question

I wanted to add element in array dynamically.Size is not fixed.Shall I use arraylist or array?Datatype is same.I am adding the value from database whose type is int.Then which datatype shall I used?How to add and remove a value from array or arraylist?

You are asking three fundamentally different questions. 1) Should I use an array list or an array? 2) How do I add a value into an array list 3) How do I add values to an array?

Use Generic List instead of ArrayList to avoid overhead of type casting.
