Write a class that holds the following personal data: name, address, age, and phone number. Store each datum in a field of an appropriate type. (Hint: What is the best type for a variable that stores a phone number? Perhaps counterintuitively, is not a numeric type. Why not?) Write getters and setters for each of your class’ fields. Demonstrate your class by writing an application program that creates three instances of it. One instance should hold your information and the other two should hold the information of two of your friends or family members.
