The internal form is an + * object having get and opt methods for accessing the + * values by name, and put methods for adding or replacing values + * by name. The values can be any of these types: Boolean, + * JSONArray, JSONObject, Number, + * String, or the JSONObject.NULL object. A JSONObject + * constructor can be used to convert an external form JSON text into an + * internal form whose values can be retrieved with the get and + * opt methods, or to convert values into a JSON text using the + * put and toString methods. 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 opt methods differ from the get methods in that they do + * not throw. Instead, they return a specified value, such as null. + *

+ * The put methods add or replace values in an object. For example, + * + * 

+ * myString = new JSONObject().put("JSON", "Hello, World!").toString();
+ *
+ * + * produces the string {"JSON": "Hello, World"}. + *

+ * The texts produced by the toString methods strictly conform to + * the JSON syntax rules. The constructors are more forgiving in the texts they + * will accept: + *

  • Strings may be quoted with ' (single + * quote).
