If the code that calls the method that throws the exception can properly deal with the exception then it should catch it. If it cannot deal with the exception then it should throw it up.
If you can handle it you handle it. For example, if you are loading a properties file and you get a FileNotFoundException perhaps you can use some default properties. In this case you handle the exception.
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.
