Class in this week's practice program, we are "stepping up our game" a bit and we are going to begin seeing a more complex, but more "real world" object oriented program structure, using a 3-tiered (business, presentation, data layer). The good news is that for the Pizza Practice program you are not going to start from scratch, and everything you are being asked to do in this program is demonstrated in the example Circle program.

If you have any questions or need any help post a question in the Programming/Practice Help discussion in the Introduction & Resources module.

Start by downloading the attached "Week5_Pizza_FileIO_Shell.zip" program, unzip the program and open it up into Netbeans. The shell project will compile and execute, and even read a stream file and populate the list with data from a string file.

Review the PizzaFileIO class and:

In the writeData method add code to add the missing order fields to the record

In the readData method add code to add the missing fields to the order object

Review the OrderList class

In the remove method add statements to remove the order from the list

In the save method add the statement to write the array list to the file.

Graphical User Interface
