public final class JSONObject
extends JSONValue
```
This class provides an implementation of a JSON value that represents an object with zero or more name-value pairs. In each pair, the name is a JSON string and the value is any type of JSON value (null, true, false, number, string, array, or object). Although the ECMA-404 specification does not explicitly forbid a JSON object from having multiple fields with the same name, RFC 7159 section 4 states that field names should be unique, and this implementation does not support objects in which multiple fields have the same name. Note that this uniqueness constraint only applies to the fields directly contained within an object, and does not prevent an object from having a field value that is an object (or that is an array containing one or more objects) that use a field name that is also in use in the outer object. Similarly, if an array contains multiple JSON objects, then there is no restriction preventing the same field names from being used in separate objects within that array.

The string representation of a JSON object is an open curly brace (U+007B) followed by a comma-delimited list of the name-value pairs that comprise the fields in that object and a closing curly brace (U+007D). Each name-value pair is represented as a JSON string followed by a colon and the appropriate string representation of the value. There must not be a comma between the last field and the closing curly brace. There may optionally be any amount of whitespace (where whitespace characters include the ASCII space, horizontal tab, line feed, and carriage return characters) after the open curly brace, on either or both sides of the colon separating a field name from its value, on either or both sides of commas separating fields, and before the closing curly brace. The order in which fields appear in the string representation is not considered significant.

The string representation returned by the toString() method (or appended to the buffer provided to the toString(StringBuilder) method) will include one space before each field name and one space before the closing curly brace. There will not be any space on either side of the colon separating the field name from its value, and there will not be any space between a field value and the comma that follows it. The string representation of each field name will use the same logic as the JSONString.toString() method, and the string representation of each field value will be obtained using that value's toString method.

The normalized string representation will not include any optional spaces, and the normalized string representation of each field value will be obtained using that value's toNormalizedString method. Field names will be treated in a case-sensitive manner, but all characters outside the LDAP printable character set will be escaped using the \u-style Unicode encoding. The normalized string representation will have fields listed in lexicographic order.
