java - 是否可以声明 String[][] 类型的全局数组？

Question

我想做的是:

class test{
public static String[][] p;

}

但是有些事情不对劲。当我尝试使用以下方法写入内容时:

p[][]={...};

它说:“p 无法解析为类型”。

编辑:好的，我发现理解我在说什么时存在一些问题，所以我在这里发布了一段代码。

public class Test{
    static String[][] plansza;
    public static void main(String []arg){

                p[][]={ {"  ","A", "B", "C", "D", "E", "F", "G", "H"},
                  {"1.","0","1","0","1","0","1","0","1"},
                  {"2.","1","0","1","0","1","0","1","0"},
                  {"3.","0","1","0","1","0","1","0","1"},
                  {"4.","0","0","0","0","0","0","0","0"},
                  {"5.","0","0","0","0","0","0","0","0"},
                  {"6.","2","0","2","0","2","0","2","0"},
                  {"7.","0","2","0","2","0","2","0","2"},
                  {"8.","2","0","2","0","2","0","2","0"}
                  };
       }

要正常创建数组，您至少需要设置数组的第一个维度，但通常您会这样做

1) 新类型[dim1][dim2]..[dimN]

如果使用诸如

之类的元素初始化数组，则可以跳过维度

2) 新类型[][]..[]{{..{元素},},..}}

但是，如果您在声明数组的同一位置使用元素初始化数组，那么您可以跳过new Type[][].. .[] 部分，只需使用 {{..{elements},},..}} 就像

3) 类型[][]..[] myArray = {{..{elements},},..}}

在您的情况下，您遇到的是情况 2)，因为您没有在声明数组的地方初始化数组。所以而不是

p[][] = {
  {"  ","A","B","C","D","E","F","G","H"},
  ...
  };

你需要将其写为

p = new String[][]{
  {"  ","A","B","C","D","E","F","G","H"},
  ...
  };
