This code has a serious security flaw in it. You're taking input from the user and passing it into database queries unvetted.
In general, the code you posted has more room for improvement, but I'd suggest you to not sink exceptions like you're doing.
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.
