Serialization (Class Reference) Problem.

Question

I have developed a class which only job is to save my serializable objects and load them. This class works very simple. In the constructor you pass the instance of the class you wish to save or load data in, and you call the method save(..) or load (..) accordingly!
Now the serialiazation works more then fine :) The problem is in the reference of classes. That is my object instance in the class responsable for serialization is initialized ok when the data is loaded. However the same object (that means passed as a paramter to the Serialiaztion class) is not being initialized.
Now as much as I know all parameters that are objects are always transfered as Reference types. That mean pointing to the same memory address. So how can my instance be initalize in one point and not in the other?
Following is my Serialization class:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
public class DataSerializer {
    private Object serializableObject;
    public DataSerializer(Object o){
        this.serializableObject = o;
    public void Save(String filePath) throws IOException{
        ObjectOutputStream objectOutputStream = null;
        try {
            objectOutputStream =
                new ObjectOutputStream(new FileOutputStream(filePath));
            objectOutputStream.writeObject(this.serializableObject);
        finally{
            try{
                objectOutputStream.flush();
                objectOutputStream.close();
            catch(Exception e){}
            objectOutputStream = null;
    public void Load(String filePath) throws ClassNotFoundException,
            ClassCastException, IOException{
        ObjectInputStream objectInputStream = null;
        try {
            objectInputStream =
                    new ObjectInputStream(new FileInputStream(filePath));
            this.serializableObject  = (AllData)objectInputStream.readObject();
            // TESTING: HERE IT RETURNS CORRECT VALUE (1)
            System.out.println("c:"+((AllMyData)this.serializableObject).count());
        finally{
            try{
                objectInputStream.close();
            catch(Exception e){}
            objectInputStream = null;
    public Object getSerializableObject(){
        return this.serializableObject;
    public void setSerializableObject(Object o){
        this.serializableObject=o;
}And this is how I call the class:
AllMyData d = new AllMyData();
d.add(new MyData("Hello"));
new DataSerializer(d).save("C:\\Test1.txt");
// Problem here:
AllMyData d2 = new AllMyData();
new DataSerializer(d2).load("C:\\Test1.txt");
System.out.println(""+d2.count);  // returns 0 instead 1!!Thanks in advance for any help!

Answer 1

BTW: By using the get and set method it works fine :)
But just a question I wanted to ask, Since from what I know about referencing it should be working like it is above!! I know it most probably is silly!? but can't explain it to myself!
here is the way I code it to work:
AllMyData d = new AllMyData();
d.add(new MyData("Hello"));
new DataSerializer(d).save("C:\\Test1.txt");
// Problem here:
AllMyData d2 = new AllMyData();
// NEW CODE BELOW
DataSerializer loader = new DataSerializer(d2);
loader .load("C:\\Test1.txt");
d2.getSerializableObject();
// NOW IT RETURNS CORRECT RESULT!
System.out.println(""+d2.count);
