8.7 Exceptions

An exception is an event that occurs during the execution of a
program that disrupts the normal flow of instructions. Java provides
checked and unchecked exceptions. For checked exceptions, where
the application can take appropriate actions for anticipated errors,
JDM provides the javax.datamining.JDMException as the base class
that inherits from the standard Java exception. JDM provides sub-
classes of JDMException to allow specialized exception handling in
applications.
Unchecked exceptions result from unanticipated application
execution failure and may require stopping the application. For
unchecked exceptions, vendors may choose among several
options: throw standard Java RuntimeException objects, wrap these
exceptions as appropriate in JDMException or JDMRuntimeExcep-
tion objects, or throw the specific JDM subclass of a Java runtime
exception.
