Question

好的，这可能是一个非常基本的问题，但我对我的生活无法弄清楚Java输出格式，我只是没有任何练习。我正在构建一个术语文档矩阵，用于计算一系列句子中某些单词的出现次数。使用以下代码

可以很好地完成矩阵

for(int i=0; i<rows; i++){
            for(int j=0; j<columns; j++){
                System.out.print(String.format("%3s", matrix[i][j]));
            }
            System.out.println("");
}

输出：

  0  0  1  0  0  0  0  0  0  0  0  1  0  0  0  0  0  0  0  1  0  1  0  1  0  0  1  0  0  1  0  0  0

但是我想添加行和列标识符，使它看起来更像这样（列标题来自字符串数组，并且会有20个句子）：

             applianc, around, autonom, averag, bath, bedroom, car, charg, drive, eat, home, hour, hous, includ, kilomet, kitchen, lap, larg, live, mile, over, per, pet, road, room, second, sedan, size, test, up, updat, veri, water
Sentence 1:

Sentence 2:

Sentence 3:
.
.
.

将行和列排列在一起，以便它们易于识别，可能使用网格或其他东西作为分隔符。我对如何实现这一点毫无头绪。

Answer 1

按照你的例子，这样的事情应该起作用

@media screen and (max-width: 680px) {
  ul.topnav li:not(:first-child) {
    display: none;
  }

  ul.topnav li {
    float:right;
  }

  ul.topnav li.icon {
    display: inline-block;
  }
}

输出：

String[] columns = {"applianc", " around", " autonom", " averag", " bath", " bedroom", " car", " charg", " drive", " eat", " home", " hour", " hous", " includ", " kilomet", " kitchen", " lap", " larg", " live", " mile", " over", " per", " pet", " road", " room", " second", " sedan", " size", " test", " up", " updat", " veri", " water"};
