Answer :

class RetailItem
{

   private String description;
   private int unitsOnHand;
   private double price;

   public RetailItem(double price, int unitsOnHand, String description)
   {
       this.price = price;
       this.unitsOnHand = unitsOnHand;
       this.description = description;
   }

   public String getDescription()

       return price;
   }
   public int getUnitsOnHand()

       System.out.println(a1.getUnitsOnHand() + " $" + a1.getPrice() + " " + a1.getDescription());
       System.out.println(a2.getUnitsOnHand() + " $" + a2.getPrice() + " " + a2.getDescription());
       System.out.println(a3.getUnitsOnHand() + " $" + a3.getPrice() + " " + a3.getDescription());
       System.out.println(a4.getUnitsOnHand() + " $" + a4.getPrice() + " " + a4.getDescription());
