This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
It's only the non-final local (method) variables that the local class cannot use. The reason is that local (method) variables are destroyed when the method exits. If these are final, then their values can be copied into any instances of the local class.
But the local class can use non-final variables outside the method (that is, members of the enclosing class).
