 * Invoking Object's clone method on an instance that does not implement the
90ce3da70b43 Initial load
duke
parents:

    35
 * <code>Cloneable</code> interface results in the exception

 * <code>CloneNotSupportedException</code> being thrown.

90ce3da70b43 Initial load

 * Note that this interface does <i>not</i> contain the <tt>clone</tt> method.
90ce3da70b43 Initial load

 * Therefore, it is not possible to clone an object merely by virtue of the
90ce3da70b43 Initial load

 * fact that it implements this interface.  Even if the clone method is invoked
90ce3da70b43 Initial load

 * reflectively, there is no guarantee that it will succeed.
