Why the inner class declared in a method can acces only the final variables.. one of the reasons i read was that since final variables are constants they exist even after the method is over. does that means that the inner class defined inside a method exists beyond the method. could i somehow access the inner class. // sorry for a silly questions... ------------------

Sure the local class object created in a method could exist afterward. Think of the case in which a method returns an object created inside the method in a local class.

Also- an inner class can access more than final variables. It can access final local variables and it can access all member (class and instance) variables of the outer class - whether final or not.

Am i right in understanding that an inner class defined inside a method cannot access local variables in other member functions of outer class. Since the scope of any local variable is only within the method where it is defined. There was a question on Marcus Green mock exam 2 which highlighted on this. I did not look it carefully and got it wrong. Can someone verify this please.

So only the vars/expressions/statements which are inside the same block can have access to them. [This message has been edited by maha anna (edited March 15, 2000).]
