- ## 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.
