The basics.

• Download the homework files from D2L, as explained here.
• Complete the files in the src directory correctly.
• Upload the homework files to D2L, as explained here.
• You can view the source code online here [source].

Notes

• Not that much has changed from hw-01.
  • There are three packages:
    • myhw2.data holds the inventory (Public javadoc) (Private javadoc)
    • myhw2.command holds the command interface -- more here next week. (Public javadoc) (Private javadoc)
    • myhw2.main holds the integration test -- more here next week.
  • There are interfaces for Video, Inventory and Record.
  • The inventory object classes are all package-private.
  • The static factory Data provides access to inventory objects.
  • The inventory interface has changed substantially:
    • toCollection has been replaced with two iterator methods: one is an unsorted iterator, the other uses the strategy pattern to return a sorted iterator.
    • The mutator methods of the inventory are all package-private.
    • To modify the inventory from outside the package, one must invoke the run method, passing in a Command object. See the example in file:myhw2/main/TEST1.java [source] [doc-public] [doc-private].
  • RecordObj is a nested class, emphasizing its dependence on InventorySet.
  • Since record objects are protected behind the public interface Record, it is no longer necessary to copy them -- they canot be modified outside the myhw2.data package.
• Complete the incomplete classes (you may wish to paste in some of your hw-01 solution).
• Modify your unit tests so that they pass. (There is no longer any need to test Record).
• Write the integration test myhw2.main.TEST1.
