Sorry to crash your parade, but you shouldn't be using an ArrayList of 3 (or any) different types to begin with. If the information is related, create a class that holds the related information and create an ArrayList that holds only one type: objects of this class.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
