Modifier and Type | Method and Description |
---|---|
void |
actionPerformed(java.awt.event.ActionEvent e)
This method handles the action events associated with the simulation buttons.
|
void |
doExperiment()
This method defines the experiment: n Bernoulli trials are performed and
the the values of the random variable are computed.
|
java.lang.String |
getAppletInfo()
This method returns basic information about the applet, including copyright
information, descriptive information, and instructions.
|
javax.swing.JTable |
getResultTable() |
void |
graphUpdate() |
void |
init()
This method initializes the experiment, including the Galton board,
random variable table and graph, and the toolbar.
|
void |
itemStateChanged(java.awt.event.ItemEvent e)
This method handles the choice event, for selecting the random variable
to display.
|
void |
reset()
This method resets the experiment, including the Galton board, the record
table, the random variable graph and table.
|
void |
run()
This method starts run mode, by first turning off the step timer if necessary.
|
void |
setDistribution()
This method sets the parameters of the distributions, and is called when
one of these parameters is changed with the scrollbar.
|
void |
stateChanged(javax.swing.event.ChangeEvent e)
This method handles the scroll events that adjust the number of trials and
the probability of success.
|
void |
step()
This method runs the experiment one time, by dropping the ball through
the Galton board.
|
void |
stop()
This method stops the experiment, by first stopping the step timer and then calling the usual
stop method.
|
void |
update()
This method updates the display, including the Galton board, the record
table, the random variable graph and table.

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.actionPerformed
