无法获取菜单，倒计时或分数计数器以在Java

标签： java swing menu frame countdown

我目前正在开发一个简单的java游戏。我总共有四个课程，Main，Countdown，Menu和MenuPanel。倒计时是一个单独的框架，我试图添加到我的主框架。菜单是我试图显示的游戏菜单，但每次我都这样，它只是一个空白的白框。我不能让这些工作。倒计时不显示，菜单只是空白。以下是我正在使用的课程：

主：     package finalproject;

    setPicture(basePic);
}}

    basePic = new Picture("backboard.jpg");
    setPicture(basePic);
}

public void processEvent(SpriteCollisionEvent ce) {
            if (ce.eventType == CollisionEventType.SPRITE) {
