java.lang.Objectjava.lang.Throwable
java.lang.Exception
java.lang.ClassNotFoundException
Thrown when an application tries to load in a class through its string name using:
forName method in class Class.
findSystemClass method in class
ClassLoader .
loadClass method in class ClassLoader.
but no definition for the class with the specified name could be found.
As of release 1.4, this exception has been retrofitted to conform to
the general purpose exception-chaining mechanism. The "optional exception
that was raised while loading the class" that may be provided at
construction time and accessed via the getException() method is
now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy method."
