Answer / ashok
Callback methods are those which are called automatically
by the application/system when a particular condition has
been met.It could be Event handling, or methods in servlet
life cycle etc.eg: Servlets callback method destroy() will
be called by the container while container is shutting
down.

Answer / robz
This type of methods are generally called by the container,
the developer does not need to call these methods
explicitly. Most of the languages specifies the callback
method by passing the address of the subroutine to the
system to the request is calling back from, But java
performs the same thing by using interfaces. Java does not
allow passing the address of subroutine but allows passing
an instance of a class that implements the standard
interface. For this purpose anonymous classes are mainly
used as they support a better compact definition of the
class that is required as a new class.
