我觉得我到处都搜索过。我相信我知道我的代码不起作用但不完全理解它或如何解决我的问题的原因。最初我尝试使用TimeUnit导入和Thread.sleep（），并且在等待给定秒数之后，这两个都更新了JFrame。我想让JFrame显示游戏结果，等待几秒钟，然后再次隐藏结果。
根据我的阅读，使用import javax.swing.Timer是我需要前进的方向，但对于我的生活，我无法弄清楚如何在我的代码中实现它。任何帮助是极大的赞赏。
//////////////以下是我认为需要编辑的代码部分//////////////// /
btnStay.addActionListener(l -> {
//System.out.println("btnStay was pressed");
btnStay.setEnabled(false);
btnHit.setEnabled(false);
btnConfirm.setVisible(false);
lblAccount.setVisible(false);

txtAccount.setVisible(false);
txtBet.setVisible(false);
d.hitUntil();
String result = g.winner();
System.out.println(result);
if(result.equals("wbj")){
account = account + (bet*1.5);
lblResult.setText("You have blackjack...");
lblResult.setVisible(true);
