Method Detail

init

public void init()

This method initializes the applet, including the sliders for the parameters of the distribution, the about button, the choice box for the type of graph, the choice box for the type of distribution, the toolbar, and the quantile and probability fields.

Overrides:

init in class java.applet.Applet

getAppletInfo

public java.lang.String getAppletInfo()

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

Overrides:

getAppletInfo in class java.applet.Applet

Returns:

applet information

actionPerformed

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

This method handles the events associated with changes in the text fields (the quantile field and the probability field), and handles events associated with the about button.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Parameters:

e - the action event

itemStateChanged

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

Parameters:

e - the change event

setDistribution

public void setDistribution()

This method sets the distribution when the parameters change.

format

public java.lang.String format(double x)
