    I am having trouble updating a TextArea. The only way I can get the TextArea to update causes a new jpanel to appear. How do I fix this and get the TextArea to properly update thanks I am using methods refresh and refresh2 at the bottom of the code.

    Code:
        private JPanel contentPane;
        private JTextField textField;
        private JTextField textField_1;
        
        String path;
        String path2;
        JButton btnLoadMpu = new JButton("");
        JButton btnLoadMpu2 = new JButton("");
        JButton btnFind1 = new JButton("Find");
        JButton btnFind2 = new JButton("Find");
        TextArea textArea_1 = new TextArea();
        TextArea textArea_2 = new TextArea();
    
        /**
         * Launch the application.
         */
        public static void main(String[] args) {
            //EventQueue.invokeLater(new Runnable() {
                //public void run() {
                //    try {
                        MPUComp frame = new MPUComp();
                        frame.setVisible(true);
                //    } catch (Exception e) {
                //        e.printStackTrace();
                //    }
            //    }
        //    });
        }
    
        /**
         * Create the frame.

    anyone I think I am not calling the right textarea and not refreshing the right jpanel?

    Since I called them in the constructor I am not sure how to call it in other methods in the same class.
