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."

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Public constructors

InvocationTargetException

Added in API level 1
public InvocationTargetException (Throwable target)

Constructs a InvocationTargetException with a target exception.

Parameters
target Throwable: the target exception

InvocationTargetException

Added in API level 1
public InvocationTargetException (Throwable target, 
                String s)

Constructs a InvocationTargetException with a target exception and a detail message.

Parameters
target Throwable: the target exception

s String: the detail message

Protected constructors

InvocationTargetException

Added in API level 1
protected InvocationTargetException ()

Constructs an InvocationTargetException with null as the target exception.

Public methods

getCause

Added in API level 1
public Throwable getCause ()

Returns the cause of this exception (the thrown target exception, which may be null).

Returns
Throwable the cause of this exception.

getTargetException

Added in API level 1
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
Throwable the thrown target exception (cause of this exception).
