Q1: Which is true about a method-local inner class?

ANS:B - It can be marked abstract.

Option B is correct because a method-local inner class can be abstract, although it means a subclass of the inner class must be created if the abstract class is to be used (so an abstract method-local inner class is probably not useful). Option A is incorrect because a method-local inner class does not have to be declared final (although it is legal to do so). C and D are incorrect because a method-local inner class cannot be made public (remember-you cannot mark any local variables as public), or static.
