Big Java example project "set"

You can use this project as follows:

 - invoke the main method of the driver class SetTest by 
 right-clicking on the class representation and selecting the main method.
 - interactive create LinkedList using "Use Library Class..." menu option in BlueJ.
 (Hint: Use full class name: java.util.HashSet)
 - interactively add values into HashSet.
 - inspect and experiment with other methods

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 20 
"Advanced Data Structures".

 - to learn about set and map data types
 - to understand the implementation of hash tables
