Non-static nested classes are called inner classes. Nested classes that are declared static are called static nested classes. A nested class is a member of its enclosing class. Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private.

It can extend exactly one class or implement exactly one interface . It can implement multiple interfaces regardless of whether it also extends a class.
Read moreWhich is true about an anonymous inner class it can extend exactly one class and implement exactly one interface it can extend exactly one class and?
Ans: C Explanation: Option C is correct because the syntax of an anonymous inner class allows for only one named type after the new , and that type must be either a single interface (in which case the anonymous class implements that one interface) or a single class (in which case the anonymous…25 Ara 2018
