            static JLabel jTextField4;
            static JTextField jTextField5;
            static JTextField jTextField6;
            static JTextField jTextField7;
            static JPasswordField jTextField8;
            static JButton jButton1;
            static Container pae;
            static JFrame frm;

public databaseAccess()
      {
      // super();
      initComponents();
      }

private void initComponents() {

                frm = new JFrame ("Database Information"); //Create frame
                frm.setSize(400,400); //Set size to 400x400 pixels
                pae = frm.getContentPane(); //Get content pane
                pae.setLayout(null); //Apply null layout
        //frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Close when X is clicked

        jButton1 = new javax.swing.JButton();
        jTextField5=new JTextField();
        jTextField6=new JTextField();
        jTextField7=new JTextField();
        jTextField8=new JPasswordField();
        jTextField1=new JLabel("Enter database name here");
        jTextField2=new JLabel("Enter table name");
        jTextField3=new JLabel("Enter user name");
        jTextField4=new JLabel("Enter password");
        jButton1=new JButton("Enter");
      // setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

              frm.add(jTextField1);
              frm.add(jTextField2);
              frm.add(jTextField3);
              frm.add(jTextField4);

            database=jTextField5.getText();
