This is a fundamental concept in Java ...3. If you want the entire structure to be serializable, then you'll need to make the parts serialiable as well. What this means in practice is that you need to make your Dragon, Hero, and Item classes implement Serializable. It's just a marker interface, so you only need to add implements Serializable.Java serialization can also be used to deep clone an object. Java cloning is the most debatable topic in Java community and it surely does have its drawbacks but it is still the most popular and easy way of creating a copy of an object until that object is full filling mandatory conditions of Java cloning.

Mar 5, 2020 · The Serializable Interface. In Java, serialization is achieved via the Serializable interface. A class that is interested in serialization implements this interface during its design. As a result, the instances of this class can be saved and restored, availing the facilities of the serialization mechanism. The Serializable interface contains no ... 2 days ago · When a class implements the java.io.Serializable interface, the JVM takes full responsibility for serializing the class instance. In case of Externalizable, it’s the programmer who should take care of the whole serialization and also deserialization process. Use Case; If we need to serialize the entire object, the Serializable interface is a ... Since serialization is intended to allow the transport of an object from one virtual machine to some other (either over space, as it is used in RMI, or over time, as when the stream is saved to a file), the mechanisms used for security need to be independent of the runtime environment of any particular virtual machine.
