Does the Java anonymous inner class require final method parameters?

Source: Internet
Author: User

Inner classes usually contain callbacks, and the function that references that anonymous inner class is gone, so the inner class references the outside local variable to be final, so that the variable is found when the callback is made, and if the member variable of the perimeter class does not need to be final, Because the inner class itself will contain a peripheral reference (the perimeter class. This), the callback must be accessible.
