[mustachMan]

int this code:

Item(String idIn, String nameIn, String retailIn, String quantityIn,
			boolean noDiscountIn)
		{
			id = idIn;
			name = nameIn;
			retail = Double.parseDouble(retailIn);
			quantity = Integer.parseInt(quantityIn);
			noDiscount = noDiscountIn;
			
			if (noDiscount == true)
				price = retail;
			
			
			else if (quantity > 400 || noDiscount == false)
				price = retail * .5D;
			else if (quantity > 200 || noDiscount == false)
				price = retail * .6D;
			else if ( noDiscount == false)
				price = retail * .7D;
				price = Math.floor(price * 100 + .5) / 100;

D tells the compiler that you mean 0.5 as a double value, not a float.

See, for instance, Data Types in Oracle's Java Tutorial.
