Serialization detection?

class MyClass implements Serializable{}

What must I write so that the Object knows when it is getting serialized and deserialized to do something before getting serialized and after getting deserialized?

You can use readObject and writeObject methods for this purpose. writeObject method will be executed when serializing your object reference.

Basically, you will do it like this:

public class MyClassToSerialize implements Serializable {
    private int data;
    /* ... methods ... */
    private void writeObject(ObjectOutputStream os) throws IOException {
        os.defaultWrite(); //serialization of the current serializable fields
        //add behavior here
    }
}

More info on the usage of these methods: http://docs.oracle.com/javase/7/docs/platform/serialization/spec/serialTOC.html
