Create a program that has at least three classes. The class with main. A class that defines a Name (first name, middle name, and last name). A class that defines a Person (name, gender, age, and salary). (You can add other classes if you want.) Then, define all setters and getters, constructors and toString methods. Then, create and attach a UML for the Person and Name classes. You do not need to create or attach a design tool for this assignment (other than the UMLs). Specifications for the main: The program will create and populate at least three different people. The program will allow a user to change the fields for a person. The program will output the data for all three people. Rules: Gender must have three possible values: M, F or O (other). Age must be between 1 and 120. Salary must be a positive number. The first and last name must be in sentence case. (Billy Armstrong) A middle name is optional (the code will account for this)
