JavaBean is a software object that interacts with other objects according to a strict set of guidelines - the JavaBean Specification. By following these guidlines, the bean can most easily be used with other objects. JavaBean is an architecture - and platform-independent set of classes for creating and using Java software components. JavaBean inherit "persistence".Persistence is handled automatically in JavaBean by using serialization mechanism. Serialization is the process of storing or retrieving information through a standard protocol. JavaBean specifies a rich of mechanisms for interaction between objects,along with common actions that most objectd will need to support,such as persistence and event handling.
With visual tools,you can use a variety of JavaBean components together without necessarily writing any code.JavaBeans components expose their own interfaces visually,providing a means to edit their properties without programming.Furthermore,by using a visual editor,you can drop a JavaBeans component directly into an application without writing any code.This is entirely new level of flexibility and reusability that was impossible in Java alone.
