Java - Can't access local jframe inside another class

Question

Hello world, I am kinda new to java and I have a problem, I am trying to access a local jframe in a different class eg

        Public class Mine extends JFrame {

           public Mine() {
               setSize(200,200);
               setTitle("Mine");
               setVisible("true");

               JButton b = new JButton("Open");
               b.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {

               JFrame fine = new JFrame("How are You");
               fine.sizeSize(200,200);
               fine.setVisible(true);
               }
               )};

           }
        }

Now I am trying to access the local JFrame which is :

      JFrame fine = new JFrame("How are you");

Please I this is not good code, all I am asking is that is there a way I can access a local JFrame in another class constructor like

It's a little difficult to ascertain what you're attempting here, or why you would want to do it, but if you want to access that JFrame fine from a different class, you should declare it as an instance variable and create an accessor method for it:

Public class Mine extends JFrame {

    private JFrame fine;

    public Mine() {
        ...
        ...
        fine = new JFrame("How are You");
        ... 
        ...
   }

   public JFrame getFine() {
       return fine;
   }
