If a class is Serializable but its super class in not, what will be the state of the instance variables inherited from super class after deserialization?

Java serialization process only continues in object hierarchy till the class is Serializable i.e. implements Serializable interface in Java and values of the instance variables inherited from super class will be initialized by calling constructor of Non-Serializable Super class during deserialization process. Once the constructor chaining will started it wouldn't be possible to stop that , hence even if classes higher in hierarchy implements Serializable interface , there constructor will be executed. As you see from the statement this Serialization interview question looks very tricky and tough but if you are familiar with key concepts its not that difficult.

Class, Reference and Object

If you like housing metaphors a  class  is like the blueprint for a house. Using this blueprint, you can build as many houses as you like. each house you build (or instantiate, in OO lingo) is an  object , also known as an  instance . each house also has an address, of course. If you want to tell someone where the house is, you give them a card with the address written on it. That card is the object's  reference . If you want to visit the house, you look at the address written on the card. This is called  dereferencing . You can copy that reference as much as you like, but there's just one house -- you're just copying the card that has the address on it, not the house itself. Java methods are always pass-by-value, but the value could be an object's reference. So, if I have: Foo myFoo = new Foo (); // 1 callBar ( myFoo ); // 2 myFoo . doSomething () // 4 void callBar ( Foo foo ) { foo = new Foo (); ...
