ClassNotFoundException
open class ClassNotFoundException : ReflectiveOperationException

Thrown when an application tries to load in a class through its string name using:
- The
forNamemethod in classClass. - The
findSystemClassmethod in classClassLoader. - The
loadClassmethod in classClassLoader.
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 java.lang.Throwable#getCause() method, as well as the aforementioned "legacy method."
