Java Serialization.

Java has a built in mechanism for converting the state of an object into a specific form of bytes. All of the data , type , and member information of the object is converted into this byte format by a process called "Serialization" and is stored in a file.

The beauty of this technique is that , that Serialization is a JVM independent process. Hence you can serialize an object from Java , and deserialize it from the .NET platform.

Transient Keyword.

The transient keyword is attached to a member field of an object , whose state you do not wish to persist during serialization.
