* A class implements the <code>Cloneable</code> interface to |

* <p> |
|
34 |
* Invoking Object's clone method on an instance that does not implement the |

* Note that this interface does <i>not</i> contain the {@code clone} method. |
2 | 44 |
* Therefore, it is not possible to clone an object merely by virtue of the |
45 |
* fact that it implements this interface. Even if the clone method is invoked |
|
46 |
* reflectively, there is no guarantee that it will succeed. |
