20.3. Basic Serialization Example

Try these first

1. 1.

   What does the Serializable interface signify in Java?

   Hint

   Think about the process of serialization.

2. 2.

   In the example, what is the purpose of the FileOutputStream?

   Hint

   Consider what happens in file handling.

3. 3.

   What is the purpose of the Serializable interface?

   • To store data in databases
   • To handle exceptions

   Hint

   Remember the context of data transfer.

4. 4.

   True or False: Deserialization is the process of converting an object into a byte stream.

   • True
   • False

   Hint

   Remember the definitions of both processes.

5. 5.

   Modify the provided Student class to include additional fields, such as email and age, and implement serialization. Discuss how these fields affect serialization.

   Hint

   Consider object integrity during serialization.

6. 6.

   Create a scenario where a serialized object's class structure changes after serialization. Explain the implications and how to handle deserialization.

   Hint

   Think about how Java checks object versions during deserialization.
