Package java.lang

package java.lang

Provides classes that are fundamental to the design of the Java Card technology subset of the Java programming language. The classes in this package are derived from java.lang in the standard Java programming language and represent the core functionality required by the Java Card Virtual Machine. This core functionality is represented by the Object class, which is the base class for all Java language classes and the Throwable class, which is the base class for the exception and runtime exception classes.

The exceptions and runtime exceptions that are included in this package are those that can be thrown by the Java Card Virtual Machine. They represent only a subset of the exceptions available in java.lang in the standard Java programming language.

Class	Description
ArithmeticException	A Java Card runtime environment-owned instance of ArithmeticException is thrown when an exceptional arithmetic condition has occurred.
ArrayIndexOutOfBoundsException	A Java Card runtime environment-owned instance of ArrayIndexOutOfBoundsException is thrown to indicate that an array has been accessed with an illegal index.
ArrayStoreException	A Java Card runtime environment-owned instance of ArrayStoreException is thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects.
ClassCastException	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.
Exception	The class Exception and its subclasses are a form of Throwable that indicate conditions that a reasonable applet might want to catch.
IndexOutOfBoundsException	A Java Card runtime environment-owned instance of IndexOutOfBoundsException is thrown to indicate that an index of some sort (such as to an array) is out of range.
NegativeArraySizeException	A Java Card runtime environment-owned instance of NegativeArraySizeException is thrown if an applet tries to create an array with negative size.
NullPointerException	A Java Card runtime environment-owned instance of NullPointerException is thrown when an applet attempts to use null in a case where an object is required.
Object	Class Object is the root of the Java Card platform class hierarchy.
RuntimeException	RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Card Virtual Machine.
SecurityException	A Java Card runtime environment-owned instance of SecurityException is thrown by the Java Card Virtual Machine to indicate a security violation.
Throwable	The Throwable class is the superclass of all errors and exceptions in the Java Card platform's subset of the Java programming language.
