Question
Which of the following statements about abstract methods
in Java is true?Solution
o An abstract method is meant to be implemented (overridden) by its concrete subclasses. o A private method is not inherited by subclasses and cannot be accessed or overridden. Therefore, it makes no sense for an abstract method to be private, as it would be impossible for subclasses to provide an implementation. The compiler will produce an error if you try to declare a private abstract method.
