how to insert indefined jlabel into jscrollpane?

Question

I have many Jlabel that must be insert into jscrollpane. How can I do this? For example:

             JScrollPane scrollPane;
            JPanel pan = new JPanel();
       JLabel[] labeltitoli= new JLabel[50];
      pan.setLayout(null);

    scrollPane = new JScrollPane(pan);
    scrollPane.setBounds(653, 32, 179, 145);

     int cont=50;
     int i=0;

      for (i=0; i<cont; i++){
       labeltitoli[i] = new JLabel(" " + i);
    //how can i insert this into Jscrollpane?}

but cont it's not definend ( as my JLabel are extracted from my db). Thank's for answers.
