public class Main
extends java.applet.Applet

This is a basic skeleton application which launches the necessary code for a four-function calculator. It relies on a (Runnable) ButtonHandler to repeatedly call getButton() and consume the buttonIDs that the CalculatorGUI object produces.

Method Detail

printUsageAndQuit

public static void printUsageAndQuit()
Print the usage information to the standard error stream, and quit.


printExceptionAndQuit

public static void printExceptionAndQuit(java.lang.Exception e)
Print the exception and any other debugging information to the standard error stream, and quit.


main

public static void main(java.lang.String[] argv)
Expects a single argument on the command line, which is the name of the student's button handler class. The student's class should have a constructor that accepts either a Calculator, or nothing at all.


init

public void init()
Initilize the Calculator (as an Applet). We don't have the complications of main here because we're not worried about loading student's code.
