Class InvocationTargetException

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.ReflectiveOperationException
    - - java.lang.reflect.InvocationTargetException

All Implemented Interfaces:

Serializable
```
public class InvocationTargetException
extends ReflectiveOperationException
```
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."

```
public Throwable getTargetException()
```
    Get the thrown target exception.

    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.
