You have to create two classes The first class Employee whic

You have to create two classes. The first class \"Employee\" which included:

The private variables:

first name

last name

id number

Wage

hoursWorked

The hoursWorked variable holds how many total hours the person worked. When the hoursWorked is over 40 hours, it will be considered as over time. Wage holds how much the person makes per hour. After passing the 40 hours, they get 1.5x the wage for each additional hour worked.

The functions:

Constructors

Properties

GetGrossPay: calculate the gross pay for the employee

The second class will be \"EmployeeDemo\" class with the main function. In the main function, read the data from the \"employeeinfo.txt\" file and save the data in the array of (Employee) objects. In the file, the first number is the total number of employees and each employee\'s information. After import the data, display a menu for user to choose:

1 Display all employees

2. Add new employee

3 quit the program

(employeeinfo.txt)

Solution

1. Employee.java

package pkg;

public class Employee {
   private String firstName;
   private String lastName;
   private String idNumber;
   private double wage;
   private double hoursWorked;

   public Employee() {
       super();
   }

   public Employee(String firstName, String lastName, String idNumber,
           double wage, double hoursWorked) {
       super();
       this.firstName = firstName;
       this.lastName = lastName;
       this.idNumber = idNumber;
       this.wage = wage;
       this.hoursWorked = hoursWorked;
   }

   public double getGrossPay() {
       if (hoursWorked > 40) {
           double gp = 40 * wage + (hoursWorked - 40) * wage * 0.5;
           return gp;
       } else {
           return hoursWorked * wage;
       }

   }

   public String getFirstName() {
       return firstName;
   }

   public void setFirstName(String firstName) {
       this.firstName = firstName;
   }

   public String getLastName() {
       return lastName;
   }

   public void setLastName(String lastName) {
       this.lastName = lastName;
   }

   public String getIdNumber() {
       return idNumber;
   }

   public void setIdNumber(String idNumber) {
       this.idNumber = idNumber;
   }

   public double getWage() {
       return wage;
   }

   public void setWage(double wage) {
       this.wage = wage;
   }

   public double getHoursWorked() {
       return hoursWorked;
   }

   public void setHoursWorked(double hoursWorked) {
       this.hoursWorked = hoursWorked;
   }

   @Override
   public String toString() {
       return \"Employee [firstName=\" + firstName + \", lastName=\" + lastName
               + \", idNumber=\" + idNumber + \", wage=\" + wage
               + \", hoursWorked=\" + hoursWorked + \", Gross Pay =\"
               + getGrossPay() + \"]\";
   }
