我正在制作John Conway的生活游戏，我无法弄清楚如何更改句点，或者在程序运行时我的代码中time.scheduleAtFixedRate(task, 0, timelength)的时间长度。我试图在我的代码中使用jslider更改时间长度，但它根本不会改变。在代码中，一些是创建graphis，可以忽略，其他代码很多用于jtextfields和jbutton等东西。

问题是，计时器一旦实例化并启动，在运行时不会检查参数是否已更改。这是一种封闭。
每次更改其中一个参数时，都必须使用新参数创建一个新的计时器实例。

以下是整个GameOfLife.java。
请在当前文件中以1：1复制并粘贴。
然后重新编译项目！ （＆＃39; Hammer with a broom＆＃39; -button）。
如果你现在运行你的应用程序，一切都应该按你的意愿运行。它完美运行，我的机器上没有任何NPE ......
