I'm having some issues with Jlabel and the setText() method. Normally the setText() is supposed to clear previous text and replace with new one on button click but instead the text piles on each other.

```
    public class JFrameDemo extends JFrame{
    private JButton clearButton;
    private JLabel display;
    private JButton exitButton;
    private JButton go;
    private JTextField nameField;
    private JLabel name;

    public JFrameDemo(){
        doEnglish();
    }

    private void doEnglish(){
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        getContentPane().setLayout(null);        

        name = new JLabel("Enter Name");
        getContentPane().add(name);
        name.setBounds(5,30,300,30);        
        nameField = new JTextField();
        getContentPane().add(nameField);    
        nameField.setBounds(80,33,150,25);        

        go = new JButton("Go");
        getContentPane().add(go);
        go.setBounds(5, 65, 50, 30);
        go.addActionListener(new ActionListener() {                        
            @Override
            public void actionPerformed(ActionEvent e) {
                goButtonActionPerformed();
            }
        });
    }

    private void goButtonActionPerformed(){
        String na = nameField.getText();
                display = new JLabel();                               
                display.setText(na);
                getContentPane().add(display);
                display.setBounds(85,110,400,20);                
    }

    public static void main(String args[]){
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new JFrameDemo().setVisible(true);
            }
        });
    }
   }

```
