RetailItem Exceptions

Programming Challenge 4 of Chapter 3 required you to write a RetailItem class that held data pertaining to a retail item. Write an exception class that can be instantiated and thrown when a negative number is given for the price. Write another exception class that can be instantiated and thrown when a negative number is given for the units on hand. Demonstrate the exception classes in a program.

Programming Challenge 4

RetailItem Class

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 is a String object that holds a brief description of the item.

• unitsOnHand. The unitsOnHand field is an int variable that holds the number of units currently in inventory.

• price. The price field is a double that holds the item’s retail price.

Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them.
