Teacher Class

Consider Teacher class as a sub class of Person

1. What is the additional attribute that a teacher class can have?
2. Discuss the different types of constructor that this class can have and how will you use Super keyword?
3. Override the toString() method of person class which will display the all details of that particular person.

Create a test class and test all classes by creating their objects and by calling their toString() method.

Create a rough class diagram for above scenario.
