Goal is to provide platform-independent component architecture. Developer writes reusable software components and then puts together applications from components using a visual builder's tool.

A Java Bean is a reusable component. It is different from an ordinary class because its method signatures and class definitions allow introspection (by the application builder's tool). Introspection can find
-
properties - these can not only be inspected but set, to allow customization
-
events
-
Visual interface(BeanBox) accesses properties of individual Beans and can link them together to form complex programs

Beans also allow persistence - a bean can be customized and then stored back to disk.
|
| 4 |
A Bean implements the Java interface "Serializable" which allows the builder tool to work with design time and run time.
