Java Beans Interview Questions and Answers
Question: What is a Bean? Why is not a Bean an Applet?Answer: JavaBeans components, or Beans, are reusable software components that can be manipulated visually in a builder tool. Beans can be combined to create traditional applications, or their smaller web-oriented brethren, applets. In addition, applets can be designed to work as reusable Beans.Individual Beans will function quite differently, but typical unifying features that distinguish a Bean are: ► Introspection: enables a builder tool to analyze how a Bean works ► Customization: enables a developer to use an app builder tool to customize the appearance and behavior of a Bean ► Events: enables Beans to communicate and connect together ► Properties: enable developers to customize and program with Beans ► Persistence: enables developers to customize Beans in an app builder, and then retrieve those Beans, with customized features intact, for future use. |
