Java Programming (AAP004-3-2-JP)

Acknowledgment

This was a great opportunity for me to put into practice which we learned in few lectures

and my own development knowledge on Java Programming.

First and foremost I would our sincere graduate to My Java Programming lecturer

Mr.Dilhan Thilakarathne for his great guidance in this project.

And special thanks goes to Mr.Balachandran Gnanasekaraiyer who thought me the

concepts on Java, object oriented methods and Harvard referencing which help on this

project as well.

Finally, I would like to thank each and every person who helped me in numerous ways

to make this project a success.

Assumptions

That two players are playing the game simultaneously and sharing the same

computer and input/output devices.

That player knows the aim of the game be the first player to reach the end by

moving across the board from First Square to the hundred square.

That player knows that when the disk lands in a square with base of the ladder

that he have to move up and when he lands on a square with a snake that he

have to return to a less valued square .

That when two players are playing that the both players have equal winning

probability.

That player has basic knowledge how to deal with computer based graphical

user interfaces.

That user who runs this application have installed Java run time (JRE)

environment on his running machine.

Object Oriented Concepts

Classes

The following table shows the classes which used in this application and included

methods of them.

Class Name Purpose Included Methods/Other

Player Class To store and retrieve player information

and statistics.

getPlayerName()

setPlayerName()

setPlayerScore()

getPlayerScore()

Main Class Provide the main interface to the users

locate the snake board

Main() method

Changeplayer()

Specialvalues()

Control Class Store all the game controls ,Image

paths and button names

LoadMain()

Dice Class Generate the Dice random number and

provide it

RandomNumber()

Score Card

Class

Provide the interface for the score card Scorecard()

Welcome Class Provide interface to get the player

information

Welcome()

Music Class Store and provide sound facilities setMusic()

5


Also common methods like paint method, Action performed method will be included in

most of the classes.

Objects

Most of these classes are used in the application are used as instances of them.

Especially the instances ‘control class’ will use in commonly because most of the

application control methods are located in that class.

There will be two instances of player class will be used as player 1 and player 2 for the

two players. Because both players have most common characteristics.

Packages

In this application mainly two packages used .Classes are related to game play is falls

under com.game package and ‘control classes’ will be falls under com.game.option

package.

Getters/Setters

Getters/Setters methods are specially used in player class to retrieve and change the player information, Location and score.

6


Abstraction

According to Sun Microsystems (2009) abstraction is selecting needed characteristics

from a class.

For Example Dice may have endless characteristics like color, width, weight from them

for this application development only need few characteristics like current number, so

it’s necessary only to implement methods for needed characteristics.

Encapsulation

According to Kioskea.net(2009) it describes that encapsulation is restrict access to

certain data or in simple words hiding information .

In this application development encapsulation is used it certain matters like the current

value of a player. Using the access modifier ‘private’ the current value of a player is

hidden and given access only by its class.

Also in a another case the player count should be accessed by several classes in the

application so using access modifier ‘public ’ it given the access to the other classes .

7


Inheritance

Meyer, Bertrand (1997). Object-Oriented Software Construction, describes that

Inheritance in object oriented programming is a relationship with a abstract classes.

Most of the classes which are visible for uses are inheritances from java.awt abstract

class for example following diagram shows the inheritance of the main class in the

application.

java.lang.Object

java.awt.Component

java.awt.Container

java.awt.Window

java.awt.Frame

com.game.Main

Polymorphism

Sierra, Kathy; Bert Bates (2005). Head First Java describes that polymorphism is

means the ability to take more than one form. That means same methods can used in

different behaviors. In this application for example the paint method is used

polymorphism.

8


Logical Design

To move the Disk though the snake board a 2-Dimentional array is used. There are 100

values in the 2-Dimentional array which is same as the snake board. Nested Loop can

travel trough the array and find the necessary location. According to java API Document

an object of a class ‘Dimension’ can store an X axis and the Y axis of a given array or

an value with having the X axis and the Y axis of the location we can relocate the disk at

a given location.

β = constant distance between frame and snake board, n/m= width, height of a box ,

a=Location retrieved by 2-Dimentional array.

The equation to get the x position location is:

x=β+n∗a

The equation to get the y position location is:

y=β+m∗a

9

Snake board

Box

0,0 0,10

n

β

m

Frame


When a location with a snake or a ladder occurs there should be a proper way of

landing on the directed location. Logic for this when a number of a location with a snake

or ladder is occurred you have to redirect to the directed location .Using the same

equation above this can be achieved inside a conditional clauses like IF,ELSE or a

SWITCH .

For demonstration purposes if we think that the number occurred and it should be

redirected to the new location which have the array dimension of 4, 7

The equation to get the new X position location is:

x=β+n∗4

The equation to get the new Y position location is:

y=β+n∗7

The shifting of the players can be done though a simple Boolean logic and player

location and score can be easily retrieve using simple counting methods.

Special Features

Audio Stream

Background music and event sounds are provided using java audio streams. All the

methods that provide sound to the application are located in the ‘music’ class and

instances of this class are created to get the sounds.

According to K.Sierra, B.Bates(2005) in their book Head first java describes that in this

audio stream method the file is taken from a input stream so File not found exception,

I/O exception should be handled.

For example the setMusic method in Music class:

public void setMusic(boolean status)

throws java.io.FileNotFoundException,

java.io.IOException

The above figure shows that the setMusic method is handling both File not found

exception and I/O Exception

Java Swing

To provide message boxes to users some components in java Swing library is

used .Specially JFrame component and JOptonPane component is used to deliver

message box dialogs.

23


Figure 4 - Swing JOptionPane

Limitations

Two players have to play the game simultaneously and can NOT play only by a

single user.

The two players who have registered first have to play the game and player

names cannot be change in middle of a game.

Players have to share the same hardware resources and can NOT play using

networked environments.

When player finishes a game he has to press ‘new game’ button to start a new

game without resetting the board automatically.

Conclusion

Designing this game with object orientated concepts and java programming language is

a quiet challenge. After several weeks of coding and research I could come up with

efferent solutions which match with the assignment requirements.
