What you can expect

This book will explain how to use the following classes:

  • JSONObject
  • JSONValue
  • JSONParser
  • JSONArray
  • ParseException

An investigation into the use of the other classes and interfaces will be left as "an exercise for the student" .

Run the program

I encourage you to copy the code from Listing 1 . Execute the code and confirm that you get the same results as those shown in Figure 1 . Experiment with the code, making changes, and observing the results of your changes. Make certain that youcan explain why your changes behave as they do.

Complete program listing

Listing 1 provides the source code for the program named Code.java .
