Since this is homework we shouldn't give you the full answer. You've obviously learnt what a class is and what an instance of a class is.
Since you are trying to learn Java, I would refrain from posting the complete code. Instead let me point out issues in your code.
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.
