Solution
a. Yes, an abstract class can have a constructor.
Even though an abstract class cannot be instantiated directly, it can have constructors. These constructors are not used for creating objects directly, but they can be used when a subclass of the abstract class is instantiated. The constructor of the abstract class runs before the constructor of the subclass.
