There is a "Student" class (subclass of "User" class) already running in IRAS app. Now, if UGC gives permission to IUB tomorrow to offer Ph.D degree, then we need to extend the "Student" class to have "ResearchStudent" class. Now the question is: do we need to make the "Student" an abstract class?
Yes
No
Logically Doesn't matter
Employee is the abstract super class. Accountant, SalesExecutive & Marketing Manager are subclasses of Employee. Now paySalary() qualifies to be an abstract method of Employee class
true
false
