I have one question or infact should say I am stuck at this and looking for a solution.
Is there any way to deserialize an object even if its serialVersionUID is changed OR say to ignore this exception for that object and let it continue deserialization of other fields?

Let me explain this, Say I have a serializable class MyClass which has two fields:
—————————————-
MyClass implements Serialzable{
Class1 field1;
Class2 field2;
private static final long serialVersionUID = 1L;
}
—————————————-
Where Class1 and Class2 both are also serializable now if Class1’s UID is changed (its a third party class so out of my control) but I still want to deserailize MyClass (even with null OR default value for field1) how can I do this?

and for the nomenclature, such interfaces are called ‘Marker Interface’ in Java. Another example is Cloneable interface.

Adding to it as void writeObject(ObjectOutputStream out)and
void readObject(ObjectInputStream in) are both private methods, it means they are not extended from any class (overridden), hence do not belong to any particular class in the java API. Somethings in java are meant for JVM to invoke

@Ravi P
void writeObject(ObjectOutputStream out)and
void readObject(ObjectInputStream in) are does not belong to any class hierarchy in java API. They basically form a part of Jav serialization mechanism. whenever you serialize any object, JVM checks wether any method like writeObject(ObjectOutputStream out) has been declared. This is to intercept the normal serialization mechanism caused by calling ObjectOutputStream.writeObject.
