System.out.println（）从数据库变成表 [英] System.out.println() from database into a table

问题描述

目前，我将数据从MS Access数据库和java应用程序I system.out.print中提取到控制台。我使用/ t来分隔数据，但它显得很笨拙。我想将它放在某种桌子上以获得更令人愉悦的外观。任何帮助都会非常感谢。

At present I pull my data from an MS Access database and within a java application I system.out.print it to the console. I used /t to space out the data, however it appears awkwardly. I would like to place it in some kind of table for a more pleasing look. Any help would be great thanks.

          while(rs.next())
      {
          System.out.print(rs.getInt("season_number")+"\t");
          System.out.print(rs.getInt("season_episode_number")+"\t");
          System.out.print(rs.getInt("series_episode_number")+"\t");
          System.out.print(rs.getString("title")+"\t");
          System.out.print(rs.getString("directed_by")+"\t");
          System.out.print(rs.getString("written_by")+"\t");
          System.out.print(rs.getDate("origional_air_date")+"\t");
          System.out.println(rs.getFloat("viewing_figures")+"\t");

      }
   }

推荐答案

为了理顺你的输出，最佳解决方案是使用 System.out.printf（）。

The best solution in order to straighten your output out will be to use System.out.printf().

由于printf与C'printf非常相似，因此您可以使用控制字符来格式化输出。像这样：

Since printf is very similar to C' printf, you can use control characters in order to format the output. Like this:

System.out.printf( "%-3.2d %-20.20s\n", rs.getInt("season_number"), rs.getString("title") );
