Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

Note: To run below program, you need to add RetailItem program and the main structure as written in question made in module 4.

import java.util.Scanner;
import java.text.DecimalFormat;
public class CashRegister
{
private RetailItem item;
private double price;
private double subTotal;
private double salesTax;
private double total;
private final double TAX_RATE=0.06;
private int quantity;
private double retail;public static class retailitem
{
private String description;
private int unitsOnHand;
private double price;
public retailitem()
{

}
public retailitem(String description, int unitsOnHand, double price)
{
this.description = description;
this.unitsOnHand = unitsOnHand;
this.price = price;
}
public String getDescription()
{
return description;
}
public int getUnits()
{
return unitsOnHand;
}
public double getPrice()
{
return price;
}

public retailitem copy()
{
retailitem copy = new retailitem(description,unitsOnHand,price);
return copy;
}

public String toString()
{
return "Item is" + description + "There are"
+ unitsOnHand + " " + "left in the store" +
"It currently is selling for" + " " + price;
}

}
/**
Constructor
@param RetailItem The item to purchase.
@param quantity The number of items.
@param price The price of item.
*/

public CashRegister(RetailItem i, int q)
{
//Create a copy of the object referenced by
//Retail Item.
this.item = new RetailItem(i);
quantity = q;
}
/**
getItem method
@return A copy of the RetailItem object
for the item being purchased.
*/

public RetailItem getRetailItem()
{

//Retun a copy of the object referenced by item
RetailItem myRetailItem = new RetailItem("Designer Jeans", 40, 34.95);
CashRegister myCashRegister = new CashRegister(myRetailItem, 1);
return new RetailItem();
}

/**
The getPrice method rerurns the item's price.
@return The item's price.
*/
public double getPrice()
{
return price;
}

/**
getUnit method
@return The number of items being puchased.
*/

public int getQuantity()
{
return quantity;
}

/**
getsubtotal method
@return The subtotal of the item puchased
*/

public double getSubTotal()
{
subTotal = item.getPrice() * quantity;
return subTotal;
}

/**
getSalesTax method
@return The sales tax of the items puchased
*/

public double getTax()
{
salesTax = this.getSubTotal() * TAX_RATE;
return salesTax;
}

/**
getTotal method
@return The total of the items puchased
*/
public double getTotal()
{
total = this.getSubTotal() + this.getTax();
return total;
}
}
