Java中的二维数组

虽然我不知道如何在单词row之前打印行数，但我的代码工作得非常好。应该是第1行、第2行，依此类推。有关于如何做的线索吗？这也是以更简单的方式存储这些字符串的线索。谢谢你:

System.out.println("\t A \t B \t C \t D \t E \t F");
String [][] TwoDim = new String[13][6];
TwoDim[0][0] = "*";
TwoDim[0][1] = "*";
TwoDim[0][2] = "X";
TwoDim[0][3] = "*";
TwoDim[0][4] = "X";
TwoDim[0][5] = "X";

TwoDim[1][0] = "*";
TwoDim[1][1] = "X";
TwoDim[1][2] = "*";
TwoDim[1][3] = "X";
TwoDim[1][4] = "*";
TwoDim[1][5] = "X";

TwoDim[2][0] = "*";
TwoDim[2][1] = "*";
TwoDim[2][2] = "X";
TwoDim[2][3] = "X";
TwoDim[2][4] = "*";
TwoDim[2][5] = "X";

TwoDim[3][0] = "X";
TwoDim[3][1] = "*";
TwoDim[3][2] = "X";
TwoDim[3][3] = "*";
TwoDim[3][4] = "X";
TwoDim[3][5] = "X";

TwoDim[4][0] = "*";
TwoDim[4][1] = "X";
TwoDim[4][2] = "*";
TwoDim[4][3] = "X";
TwoDim[4][4] = "*";
TwoDim[4][5] = "*";

TwoDim[5][0] = "*";
TwoDim[5][1] = "X";
TwoDim[5][2] = "*";
TwoDim[5][3] = "*";
TwoDim[5][4] = "*";
TwoDim[5][5] = "X";

TwoDim[6][0] = "X";
TwoDim[6][1] = "*";
TwoDim[6][2] = "*";
TwoDim[6][3] = "*";
TwoDim[6][4] = "X";
TwoDim[6][5] = "X";

TwoDim[7][0] = "*";
TwoDim[7][1] = "X";
TwoDim[7][2] = "*";
TwoDim[7][3] = "X";
TwoDim[7][4] = "X";
TwoDim[7][5] = "*";

TwoDim[8][0] = "X";
TwoDim[8][1] = "*";
TwoDim[8][2] = "X";
TwoDim[8][3] = "X";
TwoDim[8][4] = "*";
TwoDim[8][5] = "X";

TwoDim[9][0] = "*";
TwoDim[9][1] = "X";
TwoDim[9][2] = "*";
TwoDim[9][3] = "X";
TwoDim[9][4] = "X";
TwoDim[9][5] = "X";

TwoDim[10][0] = "*";
TwoDim[10][1] = "*";
TwoDim[10][2] = "X";
TwoDim[10][3] = "*";
TwoDim[10][4] = "X";
TwoDim[10][5] = "*";

TwoDim[11][0] = "*";
TwoDim[11][1] = "*";
TwoDim[11][2] = "X";
TwoDim[11][3] = "X";
TwoDim[11][4] = "*";
TwoDim[11][5] = "X";

TwoDim[12][0] = "*";
TwoDim[12][1] = "*";
TwoDim[12][2] = "*";
TwoDim[12][3] = "*";
TwoDim[12][4] = "X";
TwoDim[12][5] = "*";

for(int i = 0; i<13; i++){
    System.out.print("Row \t");
    for(int j = 0; j <6; j++){
        System.out.print(TwoDim[i][j] + "\t");
    }
    System.out.println();
}

换线

System.out.print("Row \t");

对这样的事情：

System.out.print("Row " + (i + 1) + "\t");

试试这个：

System.out.print("Row \t"+i);

如果索引从1开始

 System.out.print("Row \t"+(i+1));

您是否尝试过：

for(int i = 0; i<13; i++){
   System.out.print("Row \t " + i);
   for(int j =0; j < 6; j++ {
       ...
   }
}

好的，您的行号是从0开始的，所以假设您想从1开始，就写：

---

i是数组中的第一个索引，因此对应于行。如果要使索引基于1而不是基于0，请每次输出i+1。

不要使用行和列的硬编码值，请使用以下代码：

    for(int i = 0; i<TwoDim.length; i++){   // Iterate to row count

        System.out.print("Row-"+(i+1)+"\t"); // Change i to i+1

            for(int j = 0; j <TwoDim[i].length; j++){  // Iterate the column count
                System.out.print(TwoDim[i][j] + "\t");
        }

        System.out.println();
    }

---

输出就像一个带有行和列的表@ambigram\u makerNext time，请将代码缩减为3x5矩阵，因为这足以说明问题。这将把数字放在制表符之后。此外，它将从0开始计数，而应该从1开始。这将把数字放在制表符后面。另外，它将从0开始计数，而应该从1开始。非常感谢@blalasaadri！：很高兴我能帮忙，@user3360708:-

System.out.print("Row " + i +  "\t");

    for(int i = 0; i<TwoDim.length; i++){   // Iterate to row count

        System.out.print("Row-"+(i+1)+"\t"); // Change i to i+1

            for(int j = 0; j <TwoDim[i].length; j++){  // Iterate the column count
                System.out.print(TwoDim[i][j] + "\t");
        }

        System.out.println();
    }
