Question

虽然我不知道如何在单词“row”之前打印行的编号，但我的代码工作得很好。它应该是第1行，第2行，依此类推。关于如何做的任何线索？还有一个以更简单的方式存储这些字符串的线索。谢谢youuu：）

System.out.println("\t A \t B \t C \t D \t E \t F");

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();
}

Answer 1

更改行

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

这样的事情：

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

Answer 2

嗯，i是您的行号，从0开始，所以请写（假设您要从1开始）：

for(int i = 0; i<13; i++){
    System.out.print("Row \t"+(i+1)+" ");
    for(int j = 0; j <6; j++){
        System.out.print(TwoDim[i][j] + "\t");
    }
    System.out.println();
}

Answer 3

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

i是数组中的第一个索引，因此对应于该行。如果您想基于1而不是基于0的索引，请每次输出i + 1。

Answer 4

请勿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();
    }

Answer 5

试试这个：

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

如果您的索引从1开始

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

Answer 6

你有没有尝试过：

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