Introspection, which relies on reflection and the Reflection API, is an essential mechanism that makes JavaBeans possible. Beans are independent software components that rely on their ability to communicate with other beans to get jobs done. In addition, JavaBeans-compatible application builder environments must be able to expose the properties, methods, and events encapsulated by beans to enable rapid application development (RAD). In this chapter, you explored the Java Reflection API and introspection using the java.beans.Introspector class. Now that you understand reflection and introspection, you can create bean container classes or JavaBeans development tools.
