TheNotSerializableExceptionis thrown when an instance of a class is required to have aSerializableinterface. For example, if you try to serialize an object of a class that doesn’t implementSerializable, you’ll encounter this exception. publicclassMyClass{// class contents...}publicclassMain{pub...

Toserializean object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. A Java object isserializableif its class or any of its superclasses implements either thejava.io.Serializableinterface or its subinterface,java.io.Externali...
the object's constructor is called only when a new instance of a class is created. Keeping that basic fact in mind, let's revisit our animation code. First, we instantiate an object of typePersistentAnimation, which begins the animation thread sequence. Next, we serialize the object with tha...
Kryo is a fast and efficient binary object graph serialization framework for Java. The goals of the project are high speed, low size, and an easy to use API. The project is useful any time objects need to be persisted, whether to a file, database, or over the network. Kryo can also...
