Life of final local variable

Is the life of final local variable(inside a method) same as other local variables i.e. do they die as soon as the method call is over with the stack deleted ?
If it is so then how can we aceess a final local variable inside the method local class but other local variables cannot be?
Please clarify my query.

When you create an instance of an anonymous inner class, you are effectively creating a closure, a special language construct that is said to "close over" the local variables. What happens under the hood is that the value of the final variable is copied into a synthetic instance variable of your anonymous instance. The stack-allocated final variable itself dies with the method, as usual.
