JavaBeans are software components written in the Java programming language. The JavaBeans specification by Sun Microsystems defines them as "reusable software components that can be manipulated visually in a builder tool". In spite of many similarities, JavaBeans should not be confused with Enterprise JavaBeans (EJB), a server-side component technology that is part of Java EE.
JavaBean conventions In order to function as a JavaBean class, an object class must obey certain conventions about method naming, construction, and behavior. These conventions make it possible to have tools that can use, reuse, replace, and connect JavaBeans. The required conventions are: Because these requirements are largely expressed as conventions rather than by implementing interfaces, some developers view Java Beans as Plain Old Java Objects that follow certain naming conventions. JavaBean Example
Adoption AWT, Swing, and SWT, the major Java GUI toolkits, use JavaBeans conventions for its components, which allows GUI editors like the Eclipse Visual Editor to maintain a hierarchy of components and to provide access to their properties via getters and setters. See also | ||||||||
