java - 如何使用printf以表格形式打印

问题描述

我想打印这样的东西：

===================================================================================================

       Section 1              Section 2           Section 3
--------------------------------------------------------------------------------------------------
1110 - Ahmed Sami - Active         1116 - Maher Alsolami - Active    1122 - Waleed Alamri - Active
1111 - Mohammed Turkey - Active    1117 - Mohanned Sami - Active     1123 - Sami Alghamdi - Active
1112 - Sami Omer - Active          1118 - Feras Ahmed - Active       1124 - Majed Alharbi - Active
1113 - Bander Ali - Active         1119 - Nawaf Algarni - Active     1125 - Anwar Aljohani - Active
1114 - Basem Alzahrani - Active    1120 - Fahad Alharthi - Active    1120 - Fahad Alharthi - Active 
1115 - Turkey Almutairi - Active   1121 - Anas Batarfi - Active
==================================================================================================

但我明白了：

===================================================================================================

       Section 1              Section 2           Section 3
--------------------------------------------------------------------------------------------------
1110 - Ahmed Sami - Active 1116 - Maher Alsolami - Active 
1111 - Mohammed Turkey - Active 1117 - Mohanned Sami - Active 
1112 - Sami Omer - Active 1118 - Feras Ahmed - Active 
1113 - Bander Ali - Active 1119 - Nawaf Algarni - Active 
1114 - Basem Alzahrani - Active 1120 - Fahad Alharthi - Active 
1115 - Turkey Almutairi - Active 1121 - Anas Batarfi - Active 
==================================================================================================

这是我使用的代码（代码确实给出了错误，我只想知道如何像第一个表一样排序）：

System.out.println("\nThe first distribution for students among the available sectios ");
System.out.println("===================================================================================================\n"
    + "\n"
    + "       Section 1           Section 2           Section 3\n"
    + "--------------------------------------------------------------------------------------------------");
for (int i = 0; i < 6; i++) {
   System.out.printf("%s%s%s%s", students[i].getStudID() + " - ", students[i].getFname() + " ", students[i].getLname() + " - ", students[i].getStatus() + " ");
   System.out.printf("%s%s%s%s", students[i + 6].getStudID() + " - ", students[i + 6].getFname() + " ", students[i + 6].getLname() + " - ", students[i + 6].getStatus() + " ");
   System.out.printf("%s%s%s%s", students[i + 12].getStudID() + " - ", students[i + 12].getFname() + " ", students[i + 12].getLname() + " - ", students[i + 12].getStatus() + " ");
   System.out.println("");
}

解决方案

代替%s%s%s%s，为各个部分使用足够的空间，例如在以下语句中，为%6s%20s%20s%20s保留 6 个字符宽的空间，为 保留students[i].getStudID()20 个字符宽的空间，为 保留 20 个字符宽的空间students[i].getFname()，为 保留students[i].getLname()10 个字符宽的空间students[i].getStatus()。

System.out.printf("%6s%20s%20s%10s", students[i].getStudID() + " - ", students[i].getFname() + " ", students[i].getLname() + " - ", students[i].getStatus() + " ");

您可以根据需要调整所需的空间。
