每2秒更换一次图片

Question

我堆叠了一下，如果有人有任何想法，那将会有所帮助。 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。我想要做的是当我启动程序每2秒更换4张不同的图片时，如果你有任何建议，请不要害羞。这是程序。

Answer 1

• 将Icon / ImageIcons加入Queue，Map，Array，List，Vector

• 从数组中启动Swing Timer提取Icon / ImageIcon

• 使用Icon / ImageIcons

将JLabel添加到JLabel#setIcon()

• 与Swing GUI相关的代码应该从invokeLater()初始化，更多来自Initial Threads
