如何定义半完整的多维数组？

Question

这可能是一个太愚蠢的问题，但我无法弄明白。使用这个atm

  private static String[][][] ns=new String[][][]{{{"52","14",""},{"90","34",""},{"","",""}},{{"89","",""},{"67","78",""},{"","",""}},...

其余元素是{“”，“”，“”} ..所以数组ns必须是ns [10] [3] [3]。我怎样才能定义这个而不是写所有{“”，“”，“”} ......？

Answer 1

请勿通过new T[] {}初始化您的数组。

String[][][] ns = new String[10][3][3];
for (int i = 0; i < ns.length; i++) {
    for (int j = 0; j < ns[i].length; j++) {
        for (int k = 0; k < ns[i][j].length; k++) {
            ns[i][j][k] = "";
        }
    }
}

ns[0][0][0] = "52";
ns[0][0][1] = "14";

ns[0][1][0] = "90";
ns[0][1][1] = "34";

ns[0][3][0] = "89";

ns[0][4][0] = "67";
ns[0][4][1] = "78";
