Description copied from interface: Cloneable

Creates a copy of the object.

Returns:

a copy of the object

Throws:

java.lang.CloneNotSupportedException - if the instance of the object cannot be cloned. As this is extending Cloneable so its sure it implements it, so this exception may be used for problems on specific object instances.
