Can someone help me understand why I have an error that says "Type mismatch cannot convert from Boolean to boolean".

A boolean is a primitive. A Boolean is an object that does nothing other than hold a boolean so you can deal with those things that are so picky that they only hold Objects.

I am assuming you have a Boolean that you need to get into a boolean. You can use the booleanValue method in the Boolean class. It takes a Boolean object and returns the value of it as a boolean. Something like this:
... Boolean wrappedB = new Boolean("true"); boolean b = wrappedB.booleanValue(); // the boolean b now has the value true ...
hope that helps
did I say boolean/boolean enough in that post?
