Inheritance (To do)

Add a getAge method in the Person super class
Create a new subclass Student with additional members of your choice to personalize the Student class
Create a new subclass Teacher with additional members of your choice
Override the toString method using the @Override to print a Student and teacher object with new members
Print the student and teacher.
