util.JSONArray class
util.JSONArray class is used to modify and manipulate ordered lists of values according to the syntax of JSON string.
JSON array is an ordered list of value pairs:
[234,3456,24656,34561]
[a, ab, abc, aa, aabb, aabbcc]
JSON arrays are enclosed in square brackets - [ to begin the array and ] to end it. Values are separated by , (comma):
