使用此代碼，

Form form = new Form("Sample"); 
form.setLayout(new BoxLayout(BoxLayout.Y_AXIS)); 
TextField textField = new TextField(); 
textField.setConstraint(TextField.PASSWORD | TextField.URL); 
textField.setMaxSize(100); 
form.addComponent(textField); 
form.addCommand(new Command("Exit") { 

    public void actionPerformed(ActionEvent evt) { 
     notifyDestroyed(); 
    } 
}); 
form.show();
