public class ClassCastException
extends RuntimeException

A Java Card runtime environment-owned instance of ClassCastException is thrown to indicate that the code has attempted to cast an object to a subclass of which it is not an instance. For example, the following code generates a ClassCastException:

        Object x = new OwnerPIN( (byte)3, (byte)8);
        JCSystem.getAppletShareableInterfaceObject( (AID)x, (byte)5 );

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.

This Java Card platform class's functionality is a strict subset of the definition in the JavaTM 2 Platform Standard Edition (J2SETM) API Specification.
