Domain Objects - The Bid
  • Example 4 shows the source code for the interface for the Bid object
  • A very simple object
    • Contains the amount of the bid
      • Note that this simply returns an integer
      • Defined (externally) to be the amount (in cents) of the bid
      • No formatted output methods in bean -- just business logic
    • Also contains the date the bid was made on
      • Note the use of the serializable calendar class again
