Question
An abstract class can define ____ inside of it.A) Inner abstract classB) Inner concrete classC) static methodsD) All the above
Solution
D) All the above
Explanation:
A) Inner abstract class: An abstract class can have an inner abstract class. An inner abstract class is a class that is declared within another class and is abstract.
B) Inner concrete class: An abstract class can also have an inner concrete class. An inner concrete class is a class that is declared within another class and is not abstract.
C) Static methods: An abstract class can have static methods. A static method belongs to the class rather than the instance of a class.
So, an abstract class can define an inner abstract class, an inner concrete class, and static methods inside of it. Therefore, the answer is D) All the above.
