15. Suppose the class Employee is declared as follows: public class Employee { private String name; private double baseSalary: public void setName(String newName) {...} public void setBasSalary(double newSalary){...} public String getName() {...} public double getSalary({...} } a)Declare a class Manager that inherits from the class Employee and adds an instance variable bonus for storing a salary bonus. Omit constructors and methods. ANS: b) Which instance variables does the Manager class have? c) In the manager class, provide the method overrides the getSalary method from the class Employee so that it returns the sum of the salary and the bonus d) Based on the above question, which methods does the manager class inherit? e) In the manager class, override the getName method so that managers have a before their name (such as *John Smith).
True or False A subclass can override methods from its superclass.
Create an Employee Class with the ff: attributes: = String name = double salary = String birthday = __init__(self, name, salary, birthday) = String getDetails() -- returns a String value that represents all the information of the Employee object Create a Manager class that inherits Employee, a Manager will also have the ff: = String department = __init__(self, name, salary, birthday, department) = String getDetails() -- returns a String value that represents all the information of the Manager object Create a Director class that inherits Manager, a Director will also have the ff: = double carAllowance = __init__(self, name, salary, birthday, department, carAllowance) = def playGolf() -- will print a string value '{name of director} plays golf' = String getDetails() -- returns a String value that represents all the information of the Director object Create 2 objects of each class and call their respective getDetails() method.

The ability to construct classes with more specific characteristics that share the properties and methods of existing classes is known as: Abstraction Polymorphism Inheritance of Typecasting
What is the output of the following code? Convert the abstract class into an interface and modify the codes in all classes that will maintain the same output. (Rewrite the code)
