每2秒更换一张图片

Question

我堆叠了一下，如果有人有任何想法，这将有所帮助。 所以目前该程序正在编译和运行，但我不知道如何完成它。 我正在使用eclipse。我想要做的是当我开始程序每2秒更换4张不同的图片，所以如果你有任何建议不要害羞。这是该计划。

Answer 1

• 放Icon/ImageIcons到Queue，Map，Array，List，Vector

• 通过启动Swing Timer从阵列拾取Icon/ImageIcon

• 添加Icon/ImageIcons到JLabel，通过使用JLabel#setIcon()

• 为Swing GUI相关的代码应该从invokeLater()初始化，多在Initial Threads
