Introspection:
For those who are queasy about the idea of enforced naming conventions, explicit information about a class can be provided using the BeanInfo class. When a RAD Tool wants to find out about a JavaBean, it asks with the Introspector class by name, and if the matching BeanInfo is found the tool uses the names of the properties, events and methods defined inside that pre-packaged class.
