What is serialization ?? How can we achieve it using Java and Why it is required ??

What ??
Serialization is the process of saving an object's state to a sequence of bytes; deserialization is the process of rebuilding those bytes into a live object.


How can we achieve it using Java ??


The Java Serialization API provides a standard mechanism for developers to handle object serialization


A Typical Serialization Algorithm does following:

• It writes out the metadata of the class associated with an instance.
• It recursively writes out the description of the superclass until it finds java.lang.object.
• Once it finishes writing the metadata information, it then starts with the actual data associated with the instance. But this time, it starts from the topmost superclass.
• It recursively writes the data associated with the instance, starting from the least superclass to the most-derived class.
