Write a Java class called Employee (Parts of the code is given below), which has three private

fields firstName (String), lastName (String) and yearsEmployed (double). Implement

accessor/mutator methods for the private fields and toString() method, that returns a String

representation, which contains employee name and years she was employed.

public class Employee {

private String firstName;

...

}

Write a client program called EmployeeClient that creates an instance of Employee class, sets

values for the fields (name: John Doe, yearsEmployed: 4.5), and prints out the information about

an object.

Please note that you need to create 2 source files one for the class implementation

(Employee.java) and one for the client code (EmployeeClient.java).
