未调用readObject方法

Question

I am trying to test the custom serialization but readObject() method is not being called.Although I am able to call the writeObject method. Can we overload the readObject method().

    public class Test {

        String pwd1 ;

        public static void main(String arg[]) throws IOException, ClassNotFoundException{

            FileInputStream fis = new FileInputStream("//vhub.lmera.ericsson.se//home//xsinkus//WDP//Desktop2k8R2//COMP_DOCS//Test//kusha1.ser");
            @SuppressWarnings("resource")
            ObjectInputStream ois = new ObjectInputStream(fis);
            System.out.println("I am being called ");
            SerilizationTest si = (SerilizationTest)ois.readObject();

            System.out.println("After called ");
            System.out.println(si.name);
            System.out.println(si.pwd);
            //si.readObject();
        }

          private void readObject(ObjectInputStream ois)
                    throws IOException, ClassNotFoundException {
              ois.defaultReadObject();
                     pwd1  = (String) ois.readObject();
                     System.out.println("I am in ");
                  }
    }

Your readObject method needs to reside inside the class that implements Serializable . This way, only that class reads objects in this user defined manner.

Basically, it's not calling your method because it has no idea it exists.
