Program plan:

Filename: “DiskMover.java”

This program file is used to define a class “DiskMover”. In the code,

Import the required packages.

Define a class “DiskMover”.

Define constants “BEFORE_LARGEST”, “LARGEST”, “AFTER_LARGEST”, and “DONE”.

Define the class members “source”, “target”, “disks”, “simplerMover”.

Define the “DiskMover()” constructor.

Initialize the class members “source”, “target”, “disks”.

If the value of “disk” is greater than 1,

Define the object “simplerMover” of class “DiskMover”.

Set “BEFORE_LARGEST” to “state”.

Define the “hasMoreMoves()” constructor.

Return the result of “state != DONE”.

Define the “nextMove()” constructor.

If the value of “disks” is equal to 1,

Set the “state” equal to “DONE”.

Return the “source” and “target”.

If the “state” equal to “LARGEST”,

Set the “state” equal to “AFTER_LARGEST”.

Create a variable “other” and set its value.

Define the object “simplerMover” of class “DiskMover”.

Return the “source” and “target”.

Get the move to string variable “r”.

If the condition “!simplerMover.hasMoreMoves()” is equal to true,

Check if “state==BREFORE_LARGEST”,

Set “state” equal to “LARGEST”.

Else,

Set “state” equal to “DONE”.

Return the value of “r”.

Filename: “DiskMoverDemo.java”

This program file is used to define a class “DiskMoverDemo”. In the code,

Import the required packages.

Define a class “DiskMoverDemo”.

Define the “main” method.

Define an integer variable “n”.

Define the object “mover” of “DiskMover”.

Iterate a “while” loop,

Call the method “nextMove()” using “mover” and return the value.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
