Chapter 13, Problem 6PP
Program Plan Intro
Tower of Hanoi
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”.
- Set “state” equal to “DONE”.
- If the condition “!simplerMover.hasMoreMoves()” is equal to true,
- If the value of “disks” is equal to 1,
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.
- Define the “main” method.
