Java Eclipse executable jar file?

Just a quick example of how to deal with command line options to launch different things, I would have put it into a reply to @serplat's answer but then I can't format it.

Executable JARs don't work that way. They write a manifest file in the JAR that declares where the main class is, and it runs that one. You would have to create 4 different JARs.

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.
