序列化必须将二进制对象转换为XML(或其他字符串)表示形式，以便将其存储在数据库/文件中或通过web服务调用通过网络发送。反序列化是相反的过程——将XML/字符串转换回对象。

序列化只不过是将Java支持的对象转换为文件支持的形式

                         (OR)

将Java支持的形式转换为网络支持的形式..序列化的主要范围只是将数据从一层传输到另一层…只有序列化的对象，我们可以通过网络发送。

只要考虑一下下面的想法就能理解它。

序列化:

"hello world".split() returns ['hello', 'world']

反序列化:

" ".join(['hello', 'world']) returns "hello world"

When instantiating (constructing) the actual object(the thing) from a class (blueprint) there is a need to save the object (thing) by serializing it (breaking it down to its basic atomic structure) to a space in memory. (Kind of like Star Treks Transporter). You break the thing down into it stream of information that can be transported somewhere and stored. Then when you want to reconstruct the thing you just pull the atomically stored instance back into the object. Different from instaniation.

Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization. ... This illustration shows the overall process of serialization ... Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications
