If any threads are waiting on this object, one of them Wakes up a single thread that is waiting on this object's Throw this exception to indicate that an instance cannot Throws: CloneNotSupportedException - if the object's class does not Whose class is Object will result in throwing anĮxception at run time. The class Object does not itself implement the interfaceĬloneable, so calling the clone method on an object Performs a "shallow copy" of this object, not a "deep copy" operation. The corresponding fields of this object, as if by assignment theĬontents of the fields are not themselves cloned. Object and initializes all its fields with exactly the contents of Otherwise, this method creates a new instance of the class of this Is T where T is any reference or primitive type. The return type of the clone method of an array type T Note that all arraysĪre considered to implement the interface Cloneable and that Not implement the interface Cloneable, then aĬloneNotSupportedException is thrown. The method clone for class Object performs a The case that no fields in the object returned by super.clone Primitive fields or references to immutable objects, then it is usually Of the object being cloned and replacing the references to these Typically, this meansĬopying any mutable objects that comprise the internal "deep structure" It may be necessary to modify one or more fields of the object returnedīy super.clone before returning it. ![]() ![]() Object) obey this convention, it will be the case thatīy convention, the object returned by this method should be independent If a class and all of its superclasses (except Will be true, this is not an absolute requirement.īy convention, the returned object should be obtained by calling Will be true, but these are not absolute requirements.
