In Swing, you might use a CardLayout . You can have each "page" be a card, and the name of the card (chosen when adding cards to the layout) would be equivalent to the URI you want.
My solution for doing things like this usually involves the listener pattern. In a nutshell, you reduce coupling by providing a way to send and receive events to and from interested parties (composites in this case). This is fairly easy to implement, even when retrofitting.
This way, your events and parties can change without changing the dependent code.
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.
