The Cloneable Interface has NO methods but is used to indicate that an instance of this class can be "cloned" i.e. that the clone method (defined for overarching Object class) can be used |
The Runnable Interface has one method run() which must always be overwritten and is used to indicate that class with this interface can use threads without being a subclass of Thread. Applets must use Runnable if they need explicit threads because they explicitly are a subclass of panel and as no multiple inheritance, one cannot be a subclass of two classes |
