我正在制作John Conway的人生游戏，但我不知道如何在程序运行时更改代码中的句号，或者在本例中time.scheduleAtFixedRate(task, 0, timelength)中的时间长度。我试图在我的代码中使用jslider来改变时间长度，但是它根本没有改变。在代码中，一些is创建了可以忽略的graphis，而许多其他代码是用于jtextfield和jbutton之类的东西。

下面是整个GameOfLife.java。

请将其以1:1的比例复制粘贴到当前文件中。

然后重新编译项目！(‘拿着扫把的锤子’-按钮)。

如果你现在运行你的应用程序，一切都应该是你想要的那样运行。它运行得很好，在我的机器上没有任何NPE...
