Serialization:- Serialization can also cause breakage of singleton property of singleton classes. Serialization is used to convert an object of byte stream and save in a file or send over a network. Suppose you serialize an object of a singleton class. Then if you de-serialize that object it will create a new instance and hence break the singleton pattern. As you can see, hashCode of both instances is different, hence there are 2 objects of a singleton class. Thus, the class is no more singleton. Above both hashcodes are same hence no other instance is created. Cloning: Cloning is a concept to create duplicate objects. Using clone we can create copy of object. Suppose, we create clone of a singleton object, then it wil create a copy that is there are two instances of a singleton class, hence the class is no more singleton. Two different hashCode means there are 2 different objects of singleton class.
