Reflection


Enables Java code to discover information about the fields, methods and constructors of loaded classes, and to use reflected fields, methods, and constructors to operate on their underlying counterparts on objects, within security restrictions. The API accommodates applications that need access to either the public members of a target object (based on its runtime class) or the members declared by a given class.



Reflection is required for Introspection, the teqniche used by Beans to obtain information on the methods defined in a Bean

In other words, Reflection is a form of RTTI (Run Time Type Information) that allows you to obtain the names and referances of the methods defined in a given class.
