public interface Cloneable
Cloneableinterface to indicate to the
Object.clone()method that it is legal for that method to make a field-for-field copy of instances of that class.
Invoking Object's clone method on an instance that does not implement the
interface results in the exception
CloneNotSupportedException being thrown.
By convention, classes that implement this interface should override Object.clone (which
is protected) with a public method. See
Object.clone() for details on
overriding this method.
Note that this interface does not contain the clone method. Therefore, it is not possible to clone an object merely by virtue of the fact that it implements this interface. Even if the clone method is invoked reflectively, there is no guarantee that it will succeed.
