Create a project PersonSuperclass that has four files in it:
The Person class includes instance variables that identify a person by name and age (an int value). Include accessor methods for those two attributes, as well as a celebrateBirthday method that increases the person's age by one.
The Student subclass inherits from Person, and includes a String instance variable major that identifies that student's major in school. Include a getMajor method as well.
The Instructor subclass that also inherits from Person, and includes a double variable salary that tracks the instructor's yearly pay, and a getSalary() method.
A PersonSuperclassTester program creates and tests instances of each of these classes.
