Question

这是我所做的编码。但输出是水平对齐

此文本文件如下所示：

1,2,8,4,5,6,7,7，

3,4,5,6,7,8,

5,6,7,8,9,9,

1,2,3,4,5,8,9,0,

我希望结果看起来像这样：

2 8 4 5 6 7 7 

4 5 6 7 8

6 7 8 9 9

2 3 4 5 8 9 0

代码：

        Scanner scanner = new Scanner(new File("test.txt"));

        int row = 0;
        int col = 0;

while (scanner.hasNextLine())
{
    String currentline = scanner.nextLine();

    row++;

    String[] items = currentline.split(",");
    int[] intitems = new int[items.length];

    for (int i = 1; i < items.length; i++)
    {
        intitems[i] = Integer.parseInt(items[i]);
        System.out.println(intitems[i]);
        col = i;

    }
    col++;
    System.out.println("Column: " +col);
}

System.out.println("Row: " +row);


    }

我希望输出为垂直对齐而不是水平对齐。有办法吗？感谢

你做的一切都是正确的期待

如果你改变了

 System.out.println(intitems[i]); <- by using this line, each element is written 
                                     in new line

到

System.out.print(intitems[i] + " ");<-by using this line, each element is written in 
                                      one line till the for loop is over

所以你可以编辑这一行

System.out.println("\nColumn: " + col);

到

System.out.pritnln(); <- in order the next set of elements be written in new line

代码的for循环部分变为

       for (int i = 1; i < items.length; i++) {
            intitems[i] = Integer.parseInt(items[i]);
            System.out.print(intitems[i] + " "); <- change print to println
            col = i;

        }
        col++;
        System.out.println( ); <- get rid of the written info

水平对齐输出而不是垂直对齐
