if label is full save on another label in java

My java codes goal is to place a image on 2 labels. First the user places a image on label b2. Then the user should be able to place a image on label b33. Right now if a image is already on label b2. The image is replaced with the current one. Nothing is being saved to label b33. I want the 2nd image selected to be saved on label b33.

public class may {
  Frame f;  
 JLabel b2=new JLabel("");; 
 JLabel b33=new JLabel("");;   

may() throws IOException{ 
   f=new JFrame();  
 JButton b1 = new JButton("Import");
 b1.addActionListener(new ActionListener() {

     public void actionPerformed(ActionEvent e) {

       JFileChooser file = new JFileChooser();
       file.setCurrentDirectory(new File(System.getProperty("user.home")));
       //filter the files
       FileNameExtensionFilter filter = new FileNameExtensionFilter("*.Images", "jpg","gif","png");
       file.addChoosableFileFilter(filter);
       int result = file.showSaveDialog(null);
       if(result == JFileChooser.APPROVE_OPTION){

           //NotWorking make check null not text
           if (b2.getText().isEmpty()) {
               File selectedFile = file.getSelectedFile();
               String path = selectedFile.getAbsolutePath();
               b2.setIcon(ResizeImage(path));   
           }
           else {
               File selectedFile = file.getSelectedFile();
               String path = selectedFile.getAbsolutePath();
               b33.setIcon(ResizeImage(path));   
           }



       }


       else if(result == JFileChooser.CANCEL_OPTION){
           System.out.println("No File Select");
       }
     }
 });
 }
