Deprecated. Use the json.objects classes.
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
coersion 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:
- An extra
, (comma) may appear just
before the closing bracket.
- The
null value will be inserted when there
is , (comma) elision.
- Strings may be quoted with
' (single
quote).
- Strings do not need to be quoted at all if they do not begin with a quote
or single quote, and if they do not contain leading or trailing spaces,
and if they do not contain any of these characters:
{ } [ ] / \ : , = ; # and if they do not look like numbers
and if they are not the reserved words true,
false, or null.
- Values can be separated by
; (semicolon) as
well as by , (comma).
- Numbers may have the
0- (octal) or
0x- (hex) prefix.
- Comments written in the slashshlash, slashstar, and hash conventions
will be ignored.
