SERIALIZATION CUSTOMER:

 An Object can be directly saved into a file and can be later reloaded. This process is called Serialization and the restoration is called De-serialization. The extension of the file is ".ser".
An Object is considered ready for serialization if its class implements a Serializable interface.

The serializable interface is called Marker Interface. A Marker Interface is one that has no methods and member variables, but just indicates / marks that the given class is implementing the Interface.
Use ObjectOutputStream class for converting an object to a serialized file.

Input and Output Format:

Enter the Customer name

John

Enter the Customer number

12

Enter the Customer address

Chennai
