How Can A Sub-class Of Serializable Super Class Avoid Serialization?

1.	How Can A Sub-class Of Serializable Super Class Avoid Serialization? If Serializable Interface Is Implemented By The Super Class Of A Class, How Can The Serialization Of The Class Be Avoided?
Answer» In Java, if the super class of a class is IMPLEMENTING SERIALIZABLE interface, it means that it is already serializable. Since, an interface cannot be unimplemented, it is not possible to make a class non-serializable. However, the serialization of a new class can be avoided. For this, writeObject () and readObject() methods should be implemented in your class so that a Not Serializable Exception can be THROWN by these methods. And, this can be DONE by customizing the Java Serialization PROCESS. Below the code that demonstrates it class MySubClass extends SomeSerializableSuperClass { private void writeObject(java.io.ObjectOutputStream out) throws IOException { throw new NotSerializableException(“Can not serialize this class”); } private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException { throw new NotSerializableException(“Can not serialize this class”); } private void readObjectNoData() throws ObjectStreamException; { throw new NotSerializableException(“Can not serialize this class”); } } In Java, if the super class of a class is implementing Serializable interface, it means that it is already serializable.
