- Object models, as well as the concepts of encapsulation and polymorphism, are inexorably intertwined.arrow_forwardA subclass of an abstract class must be able to do all of the things the parent class can do. True or not?arrow_forwardEncapsulation and polymorphism, both object-oriented ideas, are linked with object models.arrow_forward
- Question 2: Recall and apply the concepts of object oriented programming (Java) (iii) We have to calculate the percentage of marks obtained in three subjects (each out of 100) by student A and in four subjects (each out of 100) by student B. Create an abstract class 'Marks' with an abstract method 'getPercentage'. It is inherited by two other classes 'A' and 'B' each having a method with the same name which returns the percentage of the students. The constructor of student A takes the marks in three subjects as its parameters and the marks in four subjects as its parameters for student B. Create an object for eac of the two classes and print the percentage of marks for both the students.arrow_forwardWhen inheriting from an abstract class, a subclass is obligated to implement each and every one of the abstract methods that the parent class provides. Is there a mistake in my understanding of this?arrow_forwardlanguage: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…arrow_forward
