Which statement is true about a static nested class?

Answer: D. It does not have access to non-static members of the enclosing class.

A static nested class does not have access to non-static members of the enclosing class.

Solution

Option A is wrong since a reference to an instance of the enclosing class is not required of static nested classes (hence cannot be used by them).

Option B is incorrect because a nested or inner class need not extend anything by default.

Option C is wrong since static nested classes can declare and define non-static members.

A static nested class cannot access the non-static members of the class because it is not connected to an instance of the enclosing class, just like a static method. Therefore, the answer to the question- Which statement is true about a static nested class is option D.
