Which of the follow are true statements. a. Any named class can be declared abstract. b. An incompletely implemented class must be declared abstract. c. A local class can be declared abstract. d. An abstract class can be instantiated. e. An abstact class is implicitly final. f. An abstact class must declare at least one abstract method. g. An abstact class can not extend a concrete class. h. None of the above. Is letter a correct ? What about classes that are already declared as final ? help! im confused
A class that is not anonymous can be declared abstract as long as it is not also declared using a modifier that is not compatible with the abstract modifier. Maybe a better way to ask that same question would be as follows. a. An anonymous class can be declared abstract. The correct answer would be "false". To avoid confusion I think I'll change answer option 'a' to the above in the next version of the exam.
