Method Detail

init

public void init()

This method initializes the experiment, including the Galton board, random variable table and graph, and the toolbar.

Overrides:

init in class Experiment

getAppletInfo

public java.lang.String getAppletInfo()

This method returns basic information about the applet, including copyright information, descriptive information, and instructions.

Specified by:

getAppletInfo in interface IExperiment

Overrides:

getAppletInfo in class Experiment

Returns:

applet information

doExperiment

public void doExperiment()

This method defines the experiment: n Bernoulli trials are performed and the the values of the random variable are computed.

Specified by:

doExperiment in interface IExperiment

Overrides:

doExperiment in class Experiment

step

public void step()

This method runs the experiment one time, by dropping the ball through the Galton board. Run mode is stopped, if necessary.

Specified by:

step in interface IExperiment

Overrides:

step in class Experiment

run

public void run()

This method starts run mode, by first turning off the step timer if necessary.

Overrides:

run in class Experiment

stop

public void stop()

This method stops the experiment, by first stopping the step timer and then calling the usual stop method.

Specified by:

stop in interface IExperiment

Overrides:

stop in class Experiment

reset

public void reset()

This method resets the experiment, including the Galton board, the record table, the random variable graph and table. The step timer is stopped if necessary.

Specified by:

reset in interface IExperiment

Overrides:

reset in class Experiment

update

public void update()

This method updates the display, including the Galton board, the record table, the random variable graph and table.

Specified by:

update in interface IExperiment

Overrides:

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent e)

This method handles the scroll events that adjust the number of trials and the probability of success.

Specified by:

stateChanged in interface javax.swing.event.ChangeListener

Overrides:

stateChanged in class Experiment

Parameters:

e - the change event

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent e)

This method handles the choice event, for selecting the random variable to display.

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

Overrides:

itemStateChanged in class Experiment

Parameters:

e - the item event

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Description copied from class: Experiment

This method handles the action events associated with the simulation buttons. The single step button calls the step method, which runs the experiment one time, and then stops. The run button calls the run method, which runs the experiment repeatedly. The stop button calls the stop method, which stops the run mode and then calls the update method if necessary. The reset button callse the reset method. The about button shows a message dialog box with the text from getAppletInfo method. This method also handles the timer events.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Overrides:

actionPerformed in class Experiment

Parameters:

e - the action event

setDistribution

public void setDistribution()

This method sets the parameters of the distributions, and is called when one of these parameters is changed with the scrollbar.

getResultTable

public javax.swing.JTable getResultTable()

Specified by:

getResultTable in interface IExperiment

Overrides:

getResultTable in class Experiment
