Line 68:

* The class must have a public [[default constructor]] (with no arguments). This allows easy instantiation within editing and activation frameworks.

* The class [[property (programming)|properties]] must be accessible using ''get'', ''set'', ''is'' (can be used for boolean properties instead of get), ''to'' and other methods (so-called [[Accessor|accessor methods]] and [[mutator method]]s) according to a standard [[naming conventions (programming)|naming convention]]. This allows easy automated inspection and updating of bean state within frameworks, many of which include custom editors for various types of properties. Setters can have one or more than one argument.

* The class should be [[Serialization#JavaProgramming language support|serializable]]. (This allows applications and frameworks to reliably save, store, and restore the bean's state in a manner independent of the [[Virtual machine|VM]] and of the platform.)
