(Done) Part 1: Write a class named RetailItem that holds data about an item in a retail store. The class should have the following fields: description. The description field references a String object that holds a brief description of the item. unitsOnHand. The unitsOnHand field is an int variable that holds the numbers of units currently in inventory. price. The price filed is a double that holds the item's retail price. Write a constructor that accepts arguments for each field, appropriate mutator methods that store values in these fields, and accessor methods that returns the values in these fields. (having Issues with) After this, write a method in the RetailItem class called purchaseItem. This method will be used to simulate an item(s) purchase. It will accept as a parameter the variable totalItemsToPurchase representing a number of units to buy (e.g. 10). The method should check if its unitsOnHand is enough to satisfy the purchase. If it is not, notify the user. If it is enough, update unitsOnHand with the new value (unitsOnHand totalItemsToPurchase) and return to the user the total cost of the purchase (itemsToPurchase * price). my code:
