我正在尝试制作PacMan游戏但尚未完成。到目前为止，我已经创建了下面的代码，没有错误。但是，它没有运行。到目前为止，我只想要出现黑色背景屏幕，墙壁和食物。
尝试运行代码时出错：
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 25
at Board.loadBoard(Board.java:92)
at Board.<init>(Board.java:71)
at PacManGUI.<init>(PacManGUI.java:11)
at PacManGame.main(PacManGame.java:8)
请帮助我成为编码的初学者并且不知道为什么会发生这种情况
