打印数组的结果为图8模式

Question

我有一个数组的结果，我想在图8中打印它们，下面是这样做的代码：

tempString2 = "\t" + trainTrack[5]+ "\n" + trainTrack[4] + "\t\t"
+ trainTrack[6] + "\n"+ trainTrack[3] + "\t\t" + trainTrack[7]+ "\n"
+ trainTrack[2] + "\t\t" + trainTrack[8]  + "\n"+ trainTrack[1]  + "\t\t"
+ trainTrack[9]  + "\n\t" + trainTrack[0]  + "\n"+ trainTrack[10] + "\t\t"
+ trainTrack[18] + "\n" + trainTrack[11] + "\t\t" + trainTrack[17] + "\n"
+ trainTrack[12] + "\t\t" + trainTrack[16] + "\n"+ trainTrack[13] + "\t\t"
+ trainTrack[15] + "\n\t" + trainTrack[14];

下面是输出字符串时所显示的内容：

      [..]
[..]        [..]
[..]        [..]
[..]        [..]
[..]        [..]
      [..]
[..]        [..]
[..]        [..]
[..]        [..]
[..]        [..]
      [..]

但有没有办法使它更美观，圆边，所以它实际上看起来像一个8？

我不确定这是否正是你想要的答案，但你可以试试这个：

tempString2 = "      " + trainTrack[5]+ "\n  " + trainTrack[4] + "    " + trainTrack[6]
    + "\n"+ trainTrack[3] + "        " + trainTrack[7]  + "\n"+ trainTrack[2] + "        "
    + trainTrack[8] + "\n  "+ trainTrack[1] + "    " + trainTrack[9] + "\n      "
    + trainTrack[0] + "\n  "+ trainTrack[10] + "    " + trainTrack[18] + "\n"+ trainTrack[11]
    + "        " + trainTrack[17]   + "\n"+ trainTrack[12] + "        " + trainTrack[16]
    + "\n  "+ trainTrack[13] + "    " + trainTrack[15] + "\n      " + trainTrack[14];

输出：

      [..]
  [..]    [..]
[..]        [..]
[..]        [..]
  [..]    [..]
      [..]
  [..]    [..]
[..]        [..]
[..]        [..]
  [..]    [..]
      [..]

您还可以使用String.format()实现相同的结果。它使一个更小、更整洁、但更不容易理解的程序：

String tempString2 = String.format("%10s\n%6s%8s\n%4s%12s\n%4s%12s\n%6s%8s\n%10s\n%6s%8s\n%4s%12s\n%4s%12s\n%6s%8s\n%10s",
    trainTrack[5], trainTrack[4], trainTrack[6], trainTrack[3], trainTrack[7], trainTrack[2],
    trainTrack[8], trainTrack[1], trainTrack[9], trainTrack[0], trainTrack[10],
    trainTrack[18], trainTrack[11], trainTrack[17], trainTrack[12], trainTrack[16],
    trainTrack[13], trainTrack[15], trainTrack[14]);

Answer 2

这个怎么样？

  [..][..]
[..]    [..]
[..]    [..]
[..]    [..]
[..][..][..]
[..]    [..]
[..]    [..]
[..]    [..]
  [..][..]

看起来更干净更合适。(也是圆的)
