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: - *

    - *
  • 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.

Its external - * form is a string wrapped in curly braces with colons between the names and - * values, and commas between the values and names. 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: - *

    - *
  • An extra , (comma) may appear just - * before the closing brace.
    • - *
  • 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.
