include java text field (textfield)

Question

I want to add this text field at my game. I’ve changed the code in my game but this one text field is being opened in a new window, but I want that text field is included in the game window itself.

Just below the "settings button".

This is my game:

I changed in my game the following lines: to include the textfield .

public MemoryGame()
    {
        createGUI();
        createJPanels();
        setArrayListText();
        window.setTitle("Jogo da Memoria");
        window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        window.setSize(WINDOW_WIDTH, WINDOW_HEIGHT);
        window.setVisible(true);
        Contador();
        //novo codigo textfield
        //... Set textarea's initial text, scrolling, and border.
        _resultArea.setText("\n");
        JScrollPane scrollingArea = new JScrollPane(_resultArea);

        //... Get the content pane, set layout, add to center
        JPanel content = new JPanel();
        content.setLayout(new BorderLayout());
        content.add(scrollingArea, BorderLayout.SOUTH);

        //... Set window characteristics.
        this.setContentPane(content);
        //this.setTitle("TextAreaDemo B");
        //this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.pack();
//fim novo codigo text field
    } 

What’s on a gray background.

Before that includes this line :72: private Jtextarea _resultArea = new Jtextarea(6, 20);

Also includes two more lines to my game:

public static void main(String[] argv)
    {      
        JFrame win = new MemoryGame();  // nova linha
        win.setVisible(true);           // nova linha
        //new MemoryGame(); */
       //... resto do codigo
     }

Everything else is the same, so I don’t want to open the textfield in a new window. But open along with the memory game, the textfield should be below the settings button or at least appear in that window, after that I try to put in place.

I’ve already lost an entire afternoon with text field and I can’t in any way put text field in the main game window.
