The util.JSONArray class provides methods to handle an array of values, following the JSON string syntax.

The util.JSONArray class is provided in the util C-Extension library. To use the util.JSONArray class, you must import the util package in your program:

A JSONArray object must be created before usage with one of the class methods like util.JSONArray.create().

The JSONArray class provides methods for accessing, adding/replacing or deleting the array values by index with the get(), put() and remove() methods.
