Problem: I need to create a 2-arg constructor to do the following
-->
2-arg constructor that accepts a RetailItem object as an argument that is used to initialize the retailCost attribute.
The 2-arg constructor is created in the CashRegister class.
here are my classes so far:
-------------------------------------------------------
/*
* Retailitem Class Modification
*/
public class RetailItem
{
//attributes
private String description; // Item description
private int itemNumber; // Item number
private CostData cost; // Cost data
//constructors
public RetailItem()
{
}//end default constructor
public RetailItem(String desc, int itemNum,
double wholesale, double retail)
{
description = desc;
itemNumber = itemNum;
cost = new CostData(wholesale, retail);
}//end 3-arg constructor
public RetailItem(String desc, double retail)
{
description = desc;
cost = new CostData(retail);
}//end 2-arg constructo
//Setters
public void setWholesaleCost(double w)
{
cost.wholesaleCost = w;
}
public void setRetailCost(double r)
{
cost.retailCost = r;
}
//Getters
public String getDescription()
{
return description;
}
public int getItemNumber()
{
return itemNumber;
}
public double getWholesaleCost()
{
return cost.wholesaleCost;
}
public double getRetailCost()
{
return cost.retailCost;
}
/**
* CostData Inner Class
*/
private class CostData
{
//attributes
public double wholesaleCost; // Wholesale cost
public double retailCost; // Retail cost
//constructors
public CostData(double w, double r)
{
wholesaleCost = w;
retailCost = r;
}//end constructor
public CostData(double retail)
{
retailCost = retail;
}//end 1-arg constructor
}//end CostData class
}//end RetailItem class------------------------------------------------------------------
public class CashRegister
{
//Attributes
public double retailCost;
public int quantity;
final double TAX_RATE = 0.06;
double subtotal;
double Tax;
double total;
// File salesReceipt;
RetailItem myRetail = new RetailItem();
//Constructors
public CashRegister()
{
}//default constructor
public CashRegister(int q)
{
//this.retailCost = r;
quantity = q;
}//end 2-arg constructor
//Methods
public double getSubTotal()
{
subtotal = retailCost*quantity;
return subtotal;
}//end getSubTotal
public double getTax()
{
Tax = retailCost*TAX_RATE;
return Tax;
}//end getTax
public double getTotal()
{
total = subtotal+Tax;
return total;
}//end getTotal
// public File createReceipt(double p,int q, double s, double st, double t )
// {
// salesReceipt = new File("salesReceipt.txt");
// return salesReceipt;
// }//end createReceipt
}//end CashRegister-------------------------------------------------------------
public class Transaction
{
//Constructors
public Transaction()
{
}//end default constructor
//Methods
public static void main(String[] args)
{
String itemName = " ";
double itemCost = 0.00;
Scanner sc = new Scanner(System.in);
NumberFormat nf = NumberFormat.getCurrencyInstance();
RetailItem myRetailItem = new RetailItem();
CashRegister myCashRegister = new CashRegister();
System.out.print("What is the name of the item being purchased? : " );
itemName = sc.nextLine();
System.out.print("What is the cost of the item? : ");
System.out.print("How many " + itemName + "(s) are you buying? ");
myCashRegister.quantity = sc.nextInt();
System.out.println();
System.out.println();
System.out.println();
System.out.print("Subtotal: " + nf.format(myCashRegister.getSubTotal()));
System.out.println();
System.out.print("Salestax: ");
System.out.println();
System.out.print("Total: ");
System.out.println();
System.out.print("Your receipt is printing.");
}//end Main
}//end classMainly I just need help in creating that 2 arg constructor.
