fashioncollection2

The document outlines the definition of a class named `Employee`, which inherits from the `Person` class and includes attributes such as salary, hire date, and social security number. It provides a set of constructors, accessor methods, mutator methods, and an equality method, along with a test program for the `Employee` class that demonstrates its functionality through multiple test cases. The test program allows users to modify employee records and validate equivalency between instances.

define a class name Employee whose objects are records for employee. Derive this class from the class person given in the listing 8.1. An employee record inherits an employee's name from the class Person. In addition, an employee record contains an annual salary represented as a single value of type double, a hire date that gives the year hired as a single value of type int, and an identification number that is a value of type String. Give your class a reasonable complement of constructors, accessor methods, and mutator methods, as well as an equals method. Write a program to fully test your class definition this is the test file import java.util.*; public class EmployeeTest { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); char repeat; do // repeat if user says 'yes' { // Test the nine constructors (uses writeOutput method) Employee e1 = new Employee(); // default constructor System.out.println("Using default constructor:"); e1.writeOutput(); System.out.println(); System.out.println("==============================="); Employee e2 = new Employee("Mondo Kane"); System.out.println("Using constructor with just name:"); e2.writeOutput(); System.out.println(); System.out.println("==============================="); Employee e3 = new Employee("Fleetis Pascal", 111111.11); System.out.println("Constructor with name & salary :");
