You are to design and then build a software simulation of a DVD player that also has WIFI capability and can connect to Netflix and play streaming video (we will keep it to Netflix at the moment). You are given the complete specification for the remote control until. It is modeled in the Analysis Classification model provided to you. Your task will be:

In assignment #4 to complete the analysis and design of the DVDPLayer class which is the model (in the MV two-tier arvchitecture) so that we can test out its functioning against the remote control before actually building the hardware DVD Player.

Implement the classes RemoteControl and DVDPlayer to demonstrate that the remote control can correctly and completely control the DVD player. For output of the DVD player functioning you can either direct status messages to the console, or build a GUI to demonstrate the DVD status. In either case, this is a view and must be totally separate from the DVDPlayer class.

System Requirements:

The remote control has been chosen. The following descriptions provide what is expected behaviour from the DVD player when each button is pressed:

HomeBtn: places the DVD player into home state and displays the home screen. If connected to the inetrnet, the connection is terminated. If a DVD is playing, it is stopped.

InternetBtn: If at home screen and internet service is available, connect to the last internet site visited (ex. Netflix). If there is no last site, go to list of sites screen. If no internet service is available, do nothing.

NavRightBtn: Move the cursor display to the right

NavLeftBtn: Move the cursor display to the left

NavUpBtn: Move the cursor display up one line

NavDownBtn: Move the cursor display down one line

PlayBtn: if a DVD is inserted and we are not in internet mode, begin playing the DVD. If

connected to an internet site, play (or select) the highlighted item (ex. Movie)

StopBtn: if playing a DVD, stop playing. If streaming an Internet movie stop and return to the

movie select screen.

PauseBtn: Pause playing the DVD or Internet movie

FFwdBtn: Fast-forward the DVD or Internet movie

FRevBtn: Fast-reverse the DVD or Internet movie

SkipSceneFwdBtn: skip one sceen forward on the DVD; if an internet movie, play in fast-forward

SkipSceneRevBtn: skip one sceen backward on the DVD; if an internet movie, play in fast-reverse

EjectBtn: If a DVD is in the drawer, open the drawer.

CloseDrawerBtn: Close the drawer if open.

OpenDrawerBtn: Open the drawer if closed.

AcceptBtn: (Internet only) Accept the highlighted item on the Internet site

PowerBtn: If DVD is currently ON, turn it OFF. If it is OFF, turn it ON.

In this part, you implement your model in Java. This part will not be marked according to how well the implementation behaves according to the description of the DVD. It will be marked according to how well you implemented your model from assignment #4. You must:

Accurately implement your model (behaviors, states, events and relationships)

Keep the model separate from the view no view code in the model; no model code in the view

You may use either a GUI or console for the view (or a combination). For example, you can have

a window GUI representing the buttons of the remote, while displaying text on the console advising what the DVD is doing. Do not incorporate input/output into the console if you use a GUI for the remote.

You may

o Make minor adjustments to your model while implementing: you may discover that you identified attributes that are, in fact, redundent or unnecessary. You may also discover the need for attributes you did not identify in the model. Also methods may be identifed in your model that you now find unnecssary, or introduce methods that are not in the model because you discovered they were necessary.

o Any deviations from the model must be well documented (i.e. why you removed the characteristic, or why you introduced a characteristic)
