Change JFrame's visibility from another class

I am coding a game in which I created a pause menu class PausePanel. In that class, I want to be able to set the JFrame of a different class, MainPanel, but whenever I make a method to do so, I get different errors/issues.

  1. Class Game is there to show the PausePanel initialization.
  2. Class PausePanel is shown because that's where I need help with the code.

  3. Class MainPanel has the JFrame I want to change the visibility of.

     public class Game extends JFrame{ //Contains the game's panel
     public static void main( String[] args){
     Game g1 = new Game();
     g1.play();
 }
 public Game(){
     setVisible(true);
     //other stuff
 }
 //other methods
 private class Keys extends KeyAdapter {
     @Override
     public void keyPressed(KeyEvent e){
     if (e.getKeyCode() == KeyEvent.VK_ESCAPE){
         setVisible(false);
         MainPanel.pause();
         PausePanel pp = new PausePanel( );
         pp.setBackground( Color.BLACK );
         pp.setPreferredSize( new Dimension(WIDTH,HEIGHT) );
         pp.setLayout( null );
}}}



public class PausePanel extends JFrame{ //Title Screen
    public PausePanel(){
        //other stuff
    }
    private class ButtonListener implements ActionListener{
        public void actionPerformed(ActionEvent e) {
            if (e.getSource().equals(continu)){
                visibility(true); <------The issue
            }
 }}} 



public class MainPanel extends JPanel{ //Actual game
    private JPanel jp = new JPanel();
    public MainPanel(){
        //stuff
    }
    public void visibility( boolean b ){ <----This is the method I'd like to be able to use
        jp.setVisible( b );
    }
}

You can use Game as a control class, that listens to PausePanel and invokes methods in MainPanel.
Alternatively you can path a reference to MainPanel instance to PasuePanel:

PausePanel pp = new PausePanel(mainPanel)
