如何關閉按鈕上的對話框窗口點擊

我使用awt和swing創建了對話框。在這種形式下，我有JTextField和okButton，它是JButton。如何使對話窗口隱藏在點擊okButton？這裏是我的類代碼：如何關閉按鈕上的對話框窗口點擊

public class QueueDialog extends JFrame implements ActionListener { 
    private static final long SerialVersionUID = 1L; 
    private static JTextField field = new JTextField(15); 
    private Sender sender; 
    private String incommingMessagesFolderUrl = "/etc/dlp/templates"; 

    public QueueDialog() throws Exception { 

    sender = new Sender(); 

    // field.setSize(60, 15); 
    JButton okButton = new JButton("ok"); 
    final JLabel label = new JLabel("Enter the name of queue:"); 
    GridBagLayout gbag = new GridBagLayout(); 
    GridBagConstraints gbc = new GridBagConstraints(); 
    setLayout(gbag); 

    gbc.insets = new Insets(2, 0, 2, 0); 
    gbc.gridy = 0; 
    gbc.gridx = 0; 
    gbag.setConstraints(label, gbc); 
    gbc.gridy = 1; 
    gbc.gridx = 0; 
    gbag.setConstraints(field, gbc); 
    gbc.gridy = 2; 
    gbc.gridx = 0; 
    gbag.setConstraints(okButton, gbc); 

    add(okButton); 
    add(field); 
    add(label); 
    setTitle("Queue name"); 
    setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE); 
    setSize(400, 200); 
    setLocationRelativeTo(null); 
    setVisible(true); 

    okButton.addActionListener(new ActionListener() { 
     @Override 
     public void actionPerformed(ActionEvent e) { 
     if (e.getActionCommand().equals("ok")) { 
      // label.setText(field.getText()); 
      send(field.getText()); 
     } 
     } 
    }); 
    } 
}

在動作監聽器寫this.setVisible（假）：P –

反正它是從來沒有好主意從構造函數中調用重寫方法，所以請爲同一個方法創建不同的方法 –

1）不要擴展框架或其他頂層容器。而是創建並使用一個實例。 2）不要設置頂級容器的大小。而是佈置內容並調用'pack（）'。 3）這不是一個對話框，而是一個框架。如果你想要一個對話框，使用'JDialog'！ –

正如我在我的評論中提到（即第一個評論）setVisible(false)正着手確定按鈕，點擊精絕

請檢查驗證碼再次在行動監聽器中添加語句的位置。剛纔這樣做是爲了證明該解決方案是正確的>我是不是下面這篇文章，希望你一定有你的答案在註釋本身

@Override

} 



public static void main(String[] args) throws Exception { 
    QueueDialog diag = new QueueDialog(); 
} 
}
