Big Java example project "input2"

You can use this project as follows:

 - invoke the main method of the driver class InputTest by right-clicking 
 on the class representation and selecting the main method.
 - interactively create DataSet objects
 - call the add method of each object 
 - then call the getAverage and getMaximum methods
 - use BlueJ's inspection capabilities to watch change of internal 
 state after each call

Note: Sometimes in BlueJ a dialog (such as input dialog or file chooser)
 appears right at the back of any open windows.  If you cannot see
 a dialog after calling the Driver class main method, minimize any 
 other windows to find the dialog.

  
This project illustrates concepts covered in Big Java, Chapter 6 
"Iteration".
  
 - to be able to program loops with the while, for, and do statements
 - to avoid infinite loops and off-by-one errors
 - to learn how to process input
