+/**
+ * A JSONArray is an ordered sequence of values. Its external text form is a
+ * string wrapped in square brackets with commas separating the values. The
+ * internal form is an object having get and opt
+ * methods for accessing the values by index, and put methods for
+ * adding or replacing values. The values can be any of these types:
+ * Boolean, JSONArray, JSONObject,
+ * Number, String, or the
+ * JSONObject.NULL object.
+ *
+ * The constructor can convert a JSON text into a Java object. The
+ * toString method converts to JSON text.
+ *
+ * A get method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An opt method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ *
+ * The generic get() and opt() methods return an
+ * object which you can cast or query for type. There are also typed
+ * get and opt methods that do type checking and type
+ * coercion for you.
+ *
+ * The texts produced by the toString methods strictly conform to
+ * JSON syntax rules. The constructors are more forgiving in the texts they will
+ * accept:
+ *
, (comma) may appear just
+ * before the closing bracket.null value will be inserted when there
+ * is , (comma) elision.' (single
+ * quote).{ } [ ] / \ : , = ; # and if they do not look like numbers
+ * and if they are not the reserved words true,
+ * false, or null.; (semicolon) as
+ * well as by , (comma).0x- (hex) prefix.[ (left bracket)
+ * and ends with ] (right bracket).
