判断:309. 在 FusionAccess 中,若 IIA 服务器与域控制器时间不同步,可能会导致系统无法正常发放并分配虚拟机桌面。

这个说法是正确的。在FusionAccess中,IIA服务器与域控制器时间不同步可能会导致系统无法正常发放并分配虚拟机桌面。这是因为在FusionAccess系统中,IIA服务器需要与域控制器进行通信来获取用户信息和桌面信息等数据。如果IIA服务器的时间与域控制器不同步,可能会导致通信失败或者获取到的数据不正确,从而导致系统无法正常发放和分配虚拟机桌面。因此,在部署FusionAccess时,需要确保IIA服务器和域控制器的时间同步,并且尽量保持时间同步的准确性。可以使用NTP等时间同步服务来实现时间同步。

这个程序使用Java Swing库来创建GUI,使用了定时器来控制游戏的速度。您可以将该代码保存为SnakeGame.java,然后在命令行中编译并运行它:
```
javac SnakeGame.java
java SnakeGame
```
注意,您需要在同级目录下创建一个名为“resources”的文件夹,并将dot.png、apple.png和head.png图像文件放在其中,以使程序能够正确加载这些图像文件。
