Don' look at me, I didn't write the textbook. I asked the instructor about it, he said Java didn't support polymorphism. I showed him his assignment points to the textbook under polymorphism and all he said was oh ok. Now you see why I am having difficulty with this class. A noob learning from an idiot. Spells success huh. Anyways I am taking macosxnerd101 advice and playing with it and see what I can do. I know he wrote the line for me but want to make sure I understand it.

I want to override inventValue(). I think I have the DigitalCamera class set up to do so. I have the inventValue() method set up in Cameras and DigitalCamera. Is this correct? I am very new to java and the book calls it polymorphism but that's a textbook for ya.

mind boggling huh?

haha I realize this. Trust me, I realize it.

if I add another ) at the end it cannot find the array.

			sort();																// sort array on output
			for(int i = 0; i<length; i++)										// loop for output from array
			// output from array
			System.out.println("Department Name: " + product[i].displayDept() + " " + "Item name: " + product[i].displayItem() + " " + "Item Number: " + product[i].itemNumber() + " " + "Units Available: " + product[i].unitsAvail() + " " + "Unit Price: $" + product[i].price() + "\n" + "Value of items in stock : $" + product[i].inventValue() + "\n" + "Value of entire inventory : $" + product[i].total_Value() + "\n");
