 String s)

Modifier	Constructor	Description
`protected`	Constructs an `InvocationTargetException` with `null` as the target exception.
	Constructs a InvocationTargetException with a target exception.
	Constructs a InvocationTargetException with a target exception and a detail message.

Method Summary

Modifier and Type	Method	Description
`Throwable`	`getCause()`	Returns the cause of this exception (the thrown target exception, which may be `null`).
`Throwable`	`getTargetException()`	Get the thrown target exception.

Methods declared in class Throwable

Modifier and Type	Method	Description
`final void`	`addSuppressed(Throwable exception)`	Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
`Throwable`	`fillInStackTrace()`	Fills in the execution stack trace.
`String`	`getLocalizedMessage()`	Creates a localized description of this throwable.
`String`	`getMessage()`	Returns the detail message string of this throwable.
`StackTraceElement[]`	`getStackTrace()`	Provides programmatic access to the stack trace information printed by `Throwable.printStackTrace()`.
`final Throwable[]`	`getSuppressed()`	Returns an array containing all of the exceptions that were suppressed, typically by the `try`-with-resources statement, in order to deliver this exception.
`Throwable`	`initCause(Throwable cause)`	Initializes the cause of this throwable to the specified value.
`void`	`printStackTrace()`	Prints this throwable and its backtrace to the standard error stream.
`void`	`printStackTrace(PrintStream s)`	Prints this throwable and its backtrace to the specified print stream.
`void`	`printStackTrace(PrintWriter s)`	Prints this throwable and its backtrace to the specified print writer.
`void`	`setStackTrace(StackTraceElement[] stackTrace)`	Sets the stack trace elements that will be returned by `Throwable.getStackTrace()` and printed by `Throwable.printStackTrace()` and related methods.
`String`	`toString()`	Returns a short description of this throwable.

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
`protected Object`	`clone()`	Creates and returns a copy of this object.
`boolean`	`equals(Object obj)`	Indicates whether some other object is "equal to" this one.
`protected void`	`finalize()`	Deprecated, for removal: This API element is subject to removal in a future version. Finalization is deprecated and subject to removal in a future release.
`final Class<?>`	`getClass()`	Returns the runtime class of this `Object`.
`int`	`hashCode()`	Returns a hash code value for this object.
`final void`	`notify()`	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.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`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(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.

Constructor Details

InvocationTargetException

protected InvocationTargetException()

Constructs an InvocationTargetException with null as the target exception.

InvocationTargetException

public InvocationTargetException(Throwable target)

Constructs a InvocationTargetException with a target exception.

Parameters:: target - the target exception, may be null

InvocationTargetException

public InvocationTargetException(Throwable target, String s)

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

Parameters:: target - the target exception, may be null; s - the detail message, may be null

Method Details

getTargetException

public Throwable getTargetException()

Get the thrown target exception.

API Note:: 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).

getCause

public Throwable getCause()

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

Overrides:: getCause in class Throwable
Returns:: the cause of this exception.
