Create a Person abstract class. The Person class must have a name, lastName and also an abstract class called getDescription() that returns a String. Create a Student class that extends the Person abstract class. Besides the properties that they inherit, for each student you must also have a courseGrade (in a percentage format i. e. 90%). For all fields you must create appropriate getters and setters and you should use appropriate access modifiers so that you use encapsulation. You must implement the getDescription function so that it returns a message: " has a grade of ", substituting all text inside <> with the equivalent values of each field.

Create a Lecturer class that extends the Person abstract class. Besides the properties that they inherit, each Lecturer must also have an ArrayList with the courses that the lecturer teaches. For all fields you must create appropriate getters and setters and you should use appropriate access modifiers so that you use encapsulation. You must implement the getDescription function so that it returns a message: " is teaching the following courses: with the equivalent values of each field.

Create a class called MainClass. Inside you must implement a main method that creates instances of the Lecturer and Student classes and invokes the method of the getDescription on each of them.
