我是Java编程的新手。在我的工作和学习场所，我要负责编写某种“战舰精简版”的程序。
到目前为止，我有以下代码：

public static final String ANSI_BLUE = "\u001B[34m";
public static final String ANSI_PURPLE = "\u001B[35m";
public static final String ANSI_CYAN = "\u001B[36m";
public static final String ANSI_WHITE = "\u001B[37m";

但是我遇到了问题-我不知道如何检查我的船在哪里。 =>我无法检查它们之间的空间。 =>他们经常彼此呆在一起。
您是否有解决此问题的想法？ 预先感谢！
