Question

Create a class Client. Your Client class should include the following attributes:

Company Name (string)

Company id (string)

Billing address (string)

Billing city (string)

Billing state (string)

Write a constructor to initialize the above Employee attributes.

Create another class HourlyClient that inherits from the Client class.   HourClient must use the inherited parent class variables and add in hourlyRate and hoursBilled. Your Hourly Client class should contain a constructor that calls the constructor from the Client class to initialize the common instance variables but also initializes the hourlyRate and hoursBilled. Add a billing method to HourlyClient to calculate the amount due from a service provided. Note that billing amount is hourlyRate * hoursBilled

Create a test class that prompts the user for the information for five hourly clients, creates an arraylist of 5 hourly client objects, display the attributes and billing for each of the five hourly clients. Display the company name and billing amount for each company and the total billing amount for all five companies.

package Array;

import java.util.ArrayList;

// Defines a class to store client information

class Client

{

// Instance variable to store client information

String companyName;

String companyId;

String billingAddress;

String billingCity;

String billingState;

// Default constructor to assign default values

// to instance variable

Client()

{

companyName = companyId = billingAddress =

billingCity = billingState = "";

}// End of default constructor

// Parameterized constructor to assign parameter values

// to instance variables

Client(String cn, String ci, String ba, String bc, String bs)

{

companyName = cn;

companyId = ci;

}// End of parameterized constructor

// Overloads toString() method to return client information

public String toString()

{

}// End of method

}// End of class Client

// Defines a derived class HourlyClient extended

// from super Client class  

class HourlyClient extends Client

{

// Instance variable to store client information

double hourlyRate;

double hoursBilled;

double billingAmount;

// Default constructor to assign default values to instance variable

HourlyClient()

{

// Calls the super class default constructor

super();

hourlyRate = hoursBilled = 0.0;

}// End of default constructor

// Parameterized constructor to assign parameter values

// to instance variables

HourlyClient(String cn, String ci, String ba,

String bc, String bs, double hr, double hb)

{

// Calls the super class parameterized constructor

hourlyRate = hr;

hoursBilled = hb;

billingAmount = 0.0;

}// End of parameterized constructor

// Method to calculate billing amount

void calculateAmount()

{

billingAmount = hourlyRate * hoursBilled;

}// End of method

// Overloads toString() method to return hourly client information

public String toString()

{

// Calls the super class toString() method

// Concatenates hourly client information

return super.toString() +

"\n Hourly Rate: " + hourlyRate +

"\n Hours Billed: " + hoursBilled +

"\n Billing Amount: " + billingAmount;

}// End of method

}// End of class HourlyClient

// Driver class definition

public class ArrayListClient

{

// main method definition

public static void main(String ss[])

{

// Creates a string array and stores company name

String companyName[] = {"Sujan", "Ambica", "Sanjibani",

// Creates a double array and stores hourly rate

double hourlyRate [] = {89.56, 55.23, 78.89, 33.45, 91.2};

// Creates a double array and stores hours billed

double hoursBilled [] ={12, 20, 10, 45, 36};

// Creates an array of object of class HourlyClient

// of size 5

HourlyClient hc[] = new HourlyClient[5];

// Creates an array list to store class HourlyClient object

ArrayList<HourlyClient> hcArray =

new ArrayList<HourlyClient>();

// Loops till number of company

for(int c = 0; c < hc.length; c++)

{

// Creates an object of class HourlyClient using

// parameterized constructor and adds it to

// array list

hcArray.add(new HourlyClient(companyName[c],

companyId[c], billingAddress[c],

billingCity[c], billingState[c],

hourlyRate[c], hoursBilled[c]));

// Calls the method to calculate amount

hcArray.get(c).calculateAmount();

// Displays each object information

System.out.println(hcArray.get(c));

}// End of for loop

}// End of main method

}// End of class
