defaultWriteObject method in serialization of java is used to read transient variable also if we use it with readObject method

Question

 private void writeObject(ObjectOutputStream o)
        throws IOException {  
        o.writeObject(propertyTwo);

        o.defaultWriteObject();  
  }

        private void readObject(ObjectInputStream o)
        throws IOException, ClassNotFoundException {

        propertyTwo = (String) o.readObject();
        o.defaultReadObject();
  }

Please explain how it serialize transient variable if we use defaultWriteObject and writeObject together?

It serializes it because you serialized it. Nothing to do with defaultWriteObject() or defaultReadObject() whatsoever. They won't serialize transient members. But you did.

But as we know f any variable is marked transient ,then that can not be serialized.

Is not serialized by default, unless you serialise it yourself, which is exactly what you have done. 'Cannot be serialized' is not correct.
