How to Access package private Class from a Class in some other package?

Not possible. The security model is this : a model to provide security :) If you designed class Hi and delivered it to customers with private access, you wouldn't like them to be able to bypass your restrictions, would you?

Yes. Reflection can be used to bypass the Java access rules, if your application has full privilege.

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.
