问题描述

我想整理下列资讯:

信息是用单元格组织的,而 System.out.println

The information is organized with cells, whereas with System.out.println the information would be very disorganized.

推荐答案

尝试使用 System.out.format()系统.out.printf() printf 只需调用格式 )。

Try using System.out.format() or System.out.printf() (printf simply invokes format so both methods gives same results).

这里有一个简单的示例,它将尝试将文本向左对齐并用空格填充未使用的位置。可以使用%-15s 实现左对齐字符串,这意味着 15 字符串的位置( s )数据并从左开始写( - )。如果要添加数字,应使用 d 后缀,如% - 4d

BTW我使用%n 而不是 \\\
来表示行当前操作系统使用的分隔符序列,对于Windows,它将是 \r\\\

Here you have simple example that will try to align text to left and fill unused places with spaces. Aligning String to left can be achieved with %-15s, which means reserve 15 places for string (s) data and start writing it from left (-). If you want to add digits use d suffix like %-4d for max 4 digit numbers that should be placed at left side of column.
BTW I used %n instead of \n to represents line separator sequence used by current OS like for Windows it will be \r\n.

您可以在。

String leftAlignFormat = "| %-15s | %-4d |%n";

System.out.format("+-----------------+------+%n");
System.out.format("| Column name     | ID   |%n");
System.out.format("+-----------------+------+%n");
for (int i = 0; i < 5; i++) {
    System.out.format(leftAlignFormat, "some data" + i, i * i);
}
System.out.format("+-----------------+------+%n");

输出

+-----------------+------+
| Column name     | ID   |
+-----------------+------+
| some data0      | 0    |
| some data1      | 1    |
| some data2      | 4    |
| some data3      | 9    |
| some data4      | 16   |
+-----------------+------+
