我正在寫一篇康威的人生遊戲遊戲，讓我幾周感到非常沮喪。到目前爲止，我已經編寫了大部分代碼，但仍然存在一些問題。我提前爲很多問題道歉。和X - -指數超出界限和多次跑步
我的人生計劃的遊戲包含30×30條線的輸入文本文件開始代表死亡的細胞和X活着。
我的問題現在就是：
- 如何處理arrayoutofbounds例外livesurrounding檢查出數組的時候？我想要做的就是忽略這些價值觀。
- 如何更改我的代碼以運行多次gens變量的值？
- 爲什麼打印copygrid總是打印地址，即使我使用Arrays.toString？
謝謝，任何幫助表示讚賞，因爲我很困惑，並用盡時間。
我的代碼：

＃1：在'liveSurrounding'，你需要決定正確的邏輯是什麼時， 「周圍」單元不在陣列中。假設你想表現得與非X的表現一樣。然後你只需在訪問周圍元素之前檢查索引，例如， if（a> 0 && grid [a-1] [b] =='X'）'，'if（b
