InvocationTargetException
Stay organized with collections

InvocationTargetException is a checked exception that wraps
an exception thrown by an invoked method or constructor.
As of release 1.4, this exception has been retrofitted to conform to
the general purpose exception-chaining mechanism. The "target exception"
that is provided at construction time and accessed via the
getTargetException()
method is now known as the cause,
and may be accessed via the Throwable.getCause()
method,
as well as the aforementioned "legacy method."

Constructs an InvocationTargetException
with
null

Public Methods
public
Throwable
getCause
()
Returns the cause of this exception (the thrown target exception,
which may be null
).
Returns
- the cause of this exception.
public
Throwable
getTargetException
()
Get the thrown target exception.
This method predates the general-purpose exception chaining facility.
The Throwable.getCause()
method is now the preferred means of
obtaining this information.
Returns
- the thrown target exception (cause of this exception).
