Local inner class An inner class that is defined within a block.

. However the inner class cannot use the variables of the outer class if they are not declared as final values. A local class can access all the variables available in the body of the code in which it is defined. The same rules for inner classes apply to local classes with the following exception.

The local classes are completely inaccessible outside the body of the code in which the class is defined. Like local variables the scope of the inner class is restricted within the method. Non-static nested class inner class Member inner class.
