public class BirthdayExperiment
extends Experiment
implements java.io.Serializable

This class models the birthday experiment: a sample of a specified size is chosen with replacement from a population of a specified size. The random variables of interest are the number of distinct values in the sample and the indicator variable that indicates a duplicate sample value.

Overrides:
init in class Experiment

getAppletInfo

public java.lang.String getAppletInfo()
This method provides 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

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent e)
This method handles the scrollbar events for adjusting the population size and sample size.

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 events associated with the random variable choice.

Specified by:
itemStateChanged in interface java.awt.event.ItemListener
Overrides:
itemStateChanged in class Experiment
Parameters:
e - the item event

setParameters

public void setParameters()
This method updates the paramerters of the distribution when these parameters have been changed with the scrollbars.
