When a superclass is abstract, you cannot instantiate objects of a superclass. How can you use a superclass abstract object?
What will be an ideal response?
When a superclass is abstract, you cannot instantiate objects of the superclass; however, you can indirectly create a reference to a superclass abstract object. A reference is not an object, but it points to a memory address. When you create a reference, you do not use the keyword new to create a concrete object; instead, you create a variable name in which you can hold the memory address of a concrete object.
