Help wanted. C++ question.

How do I declare a global object 'within' the class's brackets?

class Box{

public:
int x, y;
//Here's the problem.
Box A;//?

bool collision(Box A, Box B){}

}A, B;

Is it even possible to declare global objects within a class? Yes/no? Depending on your answer I may:
 
a) Drop out of college and become a plumber.
b) Kill myself.
c) Finish the app I'm currently working on.

You know what, nobody actually told you how to declare global variables in a class:

class someclass {
public:
static int variable;
};
now, you have someclass::variable available to you wherever you have access to someclass, and it is the same variable for all instances of someclass. In Java, this is someclass.variable.
