need in simple java

Design a class named Person and its two subclasses named Student and Employee.

A person has a name, phone number, and e-mail address.

A student has class status (freshman, sophomore, junior, or senior) and a GPA.

An employee has office, salary, and date hired.

Include in each class a constructor that has all the data fields and override the toString method to return the data fields.

Do not include getters and setters in the classes.

Write a test program that creates three objects: a Person object, a Student object, and an Employee object. Display the details of each object using its toString() method.
