将地图数组添加到java应用程序

Question

我对 Java 很陌生，但我正在尝试使用数组创建房间地图，但我不知道如何将它添加到我的应用程序类中。由于代码太长，我将分享我一直在尝试使用的视图类，以便将其添加到我的应用程序中。由于长度原因，我删除了将其他组件添加到我的应用程序的代码，但所附图片是我得到的输出。

output

任何帮助将不胜感激。我已经用尽了所有选择。谢谢。

已经在 Ubuntu 16.04 上测试过，应该也可以在 Windows 和 Java 上运行。 E 和 W 键在 Empty 和 Wall 模式之间切换。 用鼠标点击创建墙壁/删除一些！ 希望这个基础对您有所帮助...
