正如您在我的代码中看到的那样，底部有两个滚动窗格。我需要我的gui在右侧显示这两个滚动窗格，较小的一个（显示玩家拥有的当前金额，这个我需要保持一行厚）和第二个，它将不断随地吐痰输出底部玩家掷骰的信息。
另外我如何制作它以便我的组合框侦听器将每个项目的输出设置为10开始然后当它被发送出去时它再给它们1个以便它们的唯一编号从11开始那么12,13等等。

答案 0 :(得分：0)
两件事......
一，如果你已经两次添加相同的滚动窗格......
JScrollPane scrollPane = new JScrollPane();
contentPane.add(scrollPane, BorderLayout.CENTER);
JScrollPane scrollPanel = new JScrollPane();//This will hold the information the bot sends over such as win/loose or error
contentPane.add(scrollPane, BorderLayout.CENTER);
^--- Note no "l"
而且，即使您添加了两个滚动窗格实例，也已将它们添加到同一位置BorderLayout.CENTER
BorderLayout只允许将单个组件添加到它支持的其中一个可用位置，因此，在这种情况下，只有第二个滚动窗格可见
