Need help with the CashRegister Class to make a Sales Receipt?

[oneorderja]

Modifty the Cash Register Class to create a file containing a sales receipt. The program should ask the user for the quantity of the items being purchased and then generate a file with contents to similar to the following:

SALES RECEIPT
UNIT PRICE: 10.00
QUANTITY: 5
SUBTOTAL: 50
SALES TAX: 3
TOTAL: 53

My Code:

public class CashRegister
{
private RetailItem retailItem;
private int quantityItems;
private final double SALES_TAX = .06;
private int subTotal;
private double price;



public CashRegister ()
{
quantityItems = 0;
subTotal = 0;
}


public CashRegister(RetailItem retailObject, int quantity, )
{
price = retailObject.getPrice();

quantityItems = quantity;

}



public RetailItem getRetailItem()
{

return new RetailItem();
}

public double getSubTotal()
{
return quantityItems * retailItem.getPrice();
}

public double getTax()
{
return SALES_TAX;
}


public double getTotal()
{
return subTotal + SALES_TAX;
}

public String toString()
{
return " Unit Price:" + price + "Quantity:" + quantityItems;

}
}


import java.util.Scanner;

public class SalesReciept
{
public static void main (String [] args)
{

CashRegister register = new CashRegister();




}
}

Ok im trying to modify the CashRegister Class to generate a Sales Receipt with the following :
SALES RECEIPT
UNIT PRICE: 10.00
QUANTITY: 5
SUBTOTAL: 50
SALES TAX: 3
TOTAL: 53

I created the Sales Receipt class and created an instance of the CashRegister, now have no idea where to move to next.

Thanks so much!!
