我正在使用 java 创建一个老虎机游戏。用户单击“旋转按钮”后，我需要获取 3 张图片的值，这些图片将作为 GUI 中的插槽分配给 3 个标签，由 GUI 分配和数组。但是，当我在将最后一个元素分配给插槽之前添加线程来显示数组中的图片变化时，无法正确获取图片的正确值。相反，它显示分配给插槽的前 3 张图片的值。

最佳答案
Swing GUI 组件只能从 Event Dispatch Thread (EDT) 更新。
如果您尝试以固定延迟重复更新 GUI，请考虑使用 Timer执行 GUI 更新。 Timer 将按照指定的时间间隔触发 ActionEvent，并且该 ActionEvent 将出现在 EDT 上，以便您可以安全地更新 Swing 组件。
如果需要很长时间或不确定的时间来确定要加载哪些图像(可能是因为它们是从服务中获取的)，那么您可能需要添加 SwingWorker混合以避免在等待图像数组返回时阻塞 EDT。
(如果您发布 SSCCE，我将通过一个示例来更新我的答案，说明如何在代码中使用它们 - 目前缺少 Reel 和 Symbol 类会阻止您的代码编译)
* 更新 *
查看 SSCCE 后，问题似乎更多地与线程有关，而不是 EDT 和工作线程之间的交互。在下面的代码中，我做了一些更改，我相信这些更改可以解决您所描述的问题:
将检查获胜者的逻辑移至单独的线程 resultThread 上，该线程启动三个旋转器并等待其完成，然后再确定旋转是否是一个优胜者。
删除了 thread1、thread2 和 thread3 周围的 block ，以便 resultThread 可以引用它们
通过使用 SwingUtilities.invokeLater() 将 swing 组件更新移至 EDT(注意:这是 Oracle 推荐的与 Swing 组件交互的做法，但我不认为这是一个该解决方案的基本部分)
