A walking tour of JavaBean
Software components are to software what integrated circuits (ICs) are to electronics: " black boxes " that encapsulate functionality and provide services based on a specification. Software reusability has long been a holy grail of software engineering and a major goal of object-oriented programming. Software components are designed to be reusable, even interchangeable. JavaBeans are reusable software components for Java that can be manipulated visually in a builder tool.Practically, they are classes written in the Java programming language conforming to a particular convention. They are used to encapsulate many objects into a single object (the bean), so that the bean can be passed around rather than the individual objects. Java Bean A Java Bean is a java class that should follow following conventions: It should have a no-arg constructor. It should be Serializable. It should provide methods to set and get the values of the properties, known as getter ...
