- Create a class Course to describe a course according to the following requirements: A course has three attributes: courseName, courseCode, fees. Create a constructor without parameters to initialize all the instance variables to default values (0 for numbers and "" for a string). Create a constructor to initialize all the attributes to specific values. Add all setter and getter methods Create a tester class with the main method. The tester class must be named using your first and last In this class performs the following: Create a course object c1 using the default constructor. Create a course object c2 with the following information: courseName =” object oriented programing”, courseCode = “CS230” , fees = a value from your choice. Change the course fees of c2 to your age.

- Question: You are asked to create Employee class with at least 3 operational methods, then extend it to create at least two subclasses, in addition to a driver class. Make sure to use abstraction and overriding. Examples of the subclasses: Teacher and Admin Full time and Part time Manager and Assistant Examples of methods: Calculate bonus Calculate deduction Employee of the month Calculate GOSI amount Calculate retention rate Check the leave balance Feel free to add any method out of this list Please note the following: Briefly explain the idea of your system.
