java - 每 2 秒更换一次图片

Question

我有点堆积，所以如果有人有任何想法，那将会有所帮助。 所以目前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 。我想做的是当我启动程序时每 2 秒更改 4 张不同的图片，所以如果您有任何建议，请不要害羞。这是程序。

Answer 1

• 将Icon/ImageIcons放入Queue, Map, Array, List , vector

• 开始 Swing Timer从数组中取出Icon/ImageIcon

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

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