To serialize an 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 is serializable if its class or any of its superclasses implements either the java. io. Serializable interface or its subinterface, java.
object serialization is a process used to convert the state of an object into a byte stream, which can be persisted into disk/file or sent over the network to any other running java virtual machine. the reverse process of creating an object from the byte stream is called deserialization .
