public class RouletteWheel
extends javax.swing.JComponent
implements java.io.Serializable

This class models the standard American roulette wheel. The wheel has 38 slots labeled 0, 00, and 1 to 36. Of the slots labeled 1-26, 18 are red and 18 are green. The roulette wheel object is supplied with an image of a real roulette wheel.

This method paints the roulette wheel by drawing the image and drawing the ball in the appropriate slot.

Overrides:

paintComponent in class javax.swing.JComponent

Parameters:

g - the graphics context

setScore

public void setScore(int s)

This method sets the current score of the roulette wheel (the number of the slot containing the ball).

Parameters:

s - the score

spin

public int spin()

This method "spins" the wheel by selecting the score at ranom.

Returns:

the random score

getScore

public int getScore()

This method returns the current score.

Returns:

the number of the slot containing the ball

getScore

public int getScore(int i)

setBallDrawn

public void setBallDrawn(boolean b)

This method sets the boolean state of the ball.

Parameters:

b - true if the ball is drawn

isBallDrawn

public boolean isBallDrawn()

This method returns the boolean state of the ball

Returns:
