Assuming that the validators and the processor are reusable I'd take a completely other approach. I'd inject all the RecordValidators in the constructor and add a CanHandle(? packageFile) method to them and select the matching one in the loop or alternatively inject a validator selector having all the validators and get it from this one.
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.
