我有一个正在进行的简单游戏。到目前为止，我想要做的就是点击绿色按钮，让第五和第三部分切换位置。在进行arraylist中的交换之后调用paintComponent，但不刷新JPanel以显示这些更改。当我运行我的应用程序时，我选择4为每一方的碎片。因此，内部的绿色和黑色部分应该改变位置。请帮忙。

添加更多printf以获取有关正在发生的事情的更多信息。在greenMove()内，在执行交换后打印出ArrayList的内容。在paintComponent内做同样的事情。在printf中，还指示从哪里打印这些调试消息。在printComponent的循环中，在绘制时打印出每个部分的位置和颜色。
