Java. Lang. Object This class object is the root of all other class object extension hierarchy trees on the Java platform. All other classes extend the class either directly or indirectly. This class provides the default object operation method: Clone () Returns a duplicate of the object. Equals () Compare whether the object is "equal" to the specified object. The comparison rules depend entirely on the implementation of each class. Finalize () This m
