Question

道歉我的代码太乱了。我已添加并更改并注释了大量代码，并且还没有完成清理任何代码。

我的主要问题是如何获得一组5x5图像。我需要能够定期更新它，因为它是一张地图。这些更新将在与主要方法不同的方法中进行，并且很难知道特定方块中的图像是什么 - 因此我为什么要创建一个名为ArrayList的前一个地图。

这样我可以删除上一个地图的元素，然后添加新的元素。这真的很难看，所以我试图通过使用JList来改变我这样做的方式。我并不完全理解它，但在我见过的很多例子中都出现了这个问题。

我的想法是，我可以将所有25张图片（作为JLabel组件）添加到此列表中，然后将此列表添加到我希望它显示的面板中。

我也尝试使用GridLayout，因为它也出现在很多例子中。我认为网格布局的结果是我设置了一个5x5网格布局，然后使用setLayout(<GridLayout name>)到我希望网格所在的面板。然后我将想要在地图中的图像添加到此网格布局。

我的理解是否正确？我看了很多例子和解释，但我仍然不确定。我也在努力理解如何将这两个想法结合起来 - 我必须这样做吗？如果是这样，我是以正确的方式做到的？如果不是我该怎么做？

到目前为止，我已经设法得到了这个：

但是，出于某种原因，图像显示为列而不是5x5网格。这是我一直在努力的相关代码：
