I'm not sure, but it sounds like you're trying to "run" this code. This class does not have a main method - so create a class like "BoxApp" that has a main method and put it in the same folder as the Box class, and run some code like Box box1 = new Box(10, 10) Box another box = new Box(20) etc - in other words, create objects of the class you just created.
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.
