Transcribed Image Text:Question 4
(a) Define an interface called Product RegisterListener. This interface should
include a void type function called register that accepts a String parameter.
(b)
(c)
(d)
Create an abstract class called Software. Include a String attribute called name and a
double attribute called version. Ensure it can be accessed within the class hierarchy.
Include a constructor to initialize all the attributes. Create an abstract method named
about.
Create a child class called Licensed Software that inherits from the Software and
Product RegistertListener. The class should include a private member called
price as double type. Ensure that this class cannot be sub-classed. Include a constructor
to initialize the data members appropriately. Override the about method to print out all
the software details. Override the register method to pass the email address as the
parameter and it will print out the following sample output:
The software "name" registration details have been sent out
to your user@xxx.com account.
Briefly explain the Polymorphism in object-oriented programming. Use the example of
Software, LicensedSoftware and Freeware (assume another new child class)
which created in part (b) and (c), and write a code ragment to demonstrate the concept
of Polymorphism in software development.
