What is serialization and deserialization in Java?

In Java, serialization is a mechanism to persist java objects in a form of a sequence of bytes that includes the object’s data as well as information about the object’s type and its value. When there is a need to send your data object over a network or to store it in files you can use serialization. In other words, you can say that Serialization is the process for the conversion of an object code into a byte stream. Whereas, Deserialization is the reverse process of serialization, where the byte stream is used to recreate the actual Java object code in memory.
