A walk-through of the preceding program is left as an exercise for you.

EXAMPLE 8-3

Consider the following class definition:
public class Inventory
{

private String name;
private int itemNum;
private double price;
private int unitsInStock;

public Inventory() //Constructor 1

{

name = "";
itemNum = -1;
price = 0.0;
unitsInStock = 0;

}
