When an inner class refers to an instance variable that is a member of a lexically enclosing class, the variable of the corresponding lexically enclosing instance is used. A blank final (�4.5.4) field of a lexically enclosing class may not be assigned within an inner class.
If you move the declaration for str1 inside the setval() method, the code will compile. [ April 06, 2006: Message edited by: J Sato ]
