Must use Object Oriented Programming

Write a program that models an employee. An employee has an employee number, a name, an address, and a hire date. A name consists of a first name and a last name. An address consists of a street, a city, a state (2 characters), and a 5-digit zip code. A date consists of an integer month, day and year. All fields are required to be non-blank. The Date fields should be reasonably valid values (ex. month 1-12, day 1-31, year > 1900 and
