Deserialization is a process of retrieving object from byte stream. We have to fallow below steps for de-serialization
1. The object to be serialized need to implement java.io.Serializable interface.
2. It will use Java’s default serialization mechanism.
3. Generate serial version id for that serializable object.
4. Only default constructor is applicable to all class hierarchy (from child to all super classes if any). It is necessary at deserialization otherwise throw InvalidClassException.
5. Generate serial version UID for all super classes in hierarchy (all super classes if any) otherwise the properties of all its super classes will be assigned to its default value during deserializtion.
6. ObjectInputStream is used to read [readObject()] object.
7. FileInputStream is used to read from flat file.
8. The flat file extension should be (<file-name>.ser)

1. The object to be serialized need to implement java.io.Serializable / java.io. Externalizable interface.
2. Generate serial version id for that serializable object.
3. ObjectInputStream is used to read [readObject() or readExternal()] object.
4. FileInputStream is used to read from flat file.
5. The flat file extension should be (<file-name>.ser)

Can you use this() and super() both in a constructor?
all are saying java doesn't support multiple inheritance but by default Object class is super class for all the user defined classes and we can extend atmost one class so each class can extend more than one class so java supports multiple inheritance?i am confused with this,pls any one explain me.
