    Default How to use the same instance of an object in two methods

    My issue is that in my code, I create a new JFrame object called frame. In another method I want to close that frame. Any suggestions?

    // Non-relevant code
    private static class oddbutton implements ActionListener{
        public void actionPerformed(ActionEvent e) {
     
     
          }
    }
    //More Non-relevant code
     public void run(){
            NewGame.setoddnumber();
            NewGame.setevennumber();
            NewGame.separate();
            JFrame frame = new JFrame("Button Game!");
                  addComponentsToPane(frame.getContentPane());
                     Insets insets = frame.getInsets();
            frame.setSize(200, 300);
            frame.setVisible(true);
        }

    As of now, I have nothing in my oddbutton class. I don't know how to close the frame.

    Never mind. I solved my issue. All I had to do was make frame a static public object.

    Making something static to get around accessibility issues is a bad solution.

    So, what else can be the solution to OP's specified problem?
