When not to use a private field?
<p>When should it be considered dangerous to use a <strong>private</strong> field all over the place in the methods of your class?  I mostly just create the variable and set it to a default value like null.  Then in my methods reference it and set it to an instance of that object type from the methods.</p>

<p>I don't know if my question makes sense but let me know if it doesn't and I'll clarify.</p>
