public class NullPointerException

extends RuntimeException

A JCRE owned instance of NullPointerExceptionis thrown when an applet attempts to use null in a case where an object is required. These include:

• Calling the instance method of a null object.
• Accessing or modifying the field of a null object.
• Taking the length of null as if it were an array.
• Accessing or modifying the slots of null as if it were an array.
• Throwing null as if it were a Throwable value.

JCRE owned instances of exception classes are temporary JCRE 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 Java Card Runtime Environment (JCRE) Specification, section 6.2.1 for details.

This Java Card class's functionality is a strict subset of the definition in the Java Platform Core API Specification.
