Global Variables Bad
<p>Ok after reading this article and also some of the examples I am still not clear on what global variables mean.  So its say private variables in your class are global?</p>

<p>So can someone explain this to me in simple terms the context.  Does this mean even private fields at the top of your class?  I'm not clear on the definition of a "global variable" so that I can distinguish if I'm doing something "bad" in my classes.</p>
