public class UserException
extends CardException

UserException represents a User exception. This class also provides a resource-saving mechanism (the throwIt() method) for user exceptions by using a Java Card runtime environment-owned instance.

Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment Entry Point Objects and can be accessed from any applet context. References to these temporary objects cannot be stored in class variables or instance variables or array components. See Runtime Environment Specification for the Java Card Platform, section 6.2.1 for details.
