Use <a href="http://java.sun.com/javase/6/docs/api/java/io/PrintWriter.html#format(java.lang.String,%20java.lang.Object...)" rel="noreferrer" title="format(String, Object...)"><code>System.out.format</code></a> . You can set lengths of fields like this:

<pre><code>System.out.format("%32s%10d%16s", string1, int1, string2);
</code></pre>

This pads <code>string1</code>, <code>int1</code>, and <code>string2</code> to 32, 10, and 16 characters, respectively.

See the Javadocs for <a href="http://java.sun.com/javase/6/docs/api/java/util/Formatter.html" rel="noreferrer"><code>java.util.Formatter</code></a> for more information on the syntax (<code>System.out.format</code> uses a <code>Formatter</code> internally).

And it as simple as:

The API also allows sorting and row numbering ...

differece in sizes of input doesnt effect the output

I'm getting results from a database and want to output the data as a table in Java's standard output

I've tried using \t but the first column I want is very variable in length.

Is there a way to display this in a nice table like output?

Output in a table format in Java's System.out

数据库

Java

我从数据库中获取结果，并希望将数据以Java标准输出中的表的形式输出我尝试使用\t，但我想要的第一列的长度非常可变。有没有办法在像output这样漂亮的表格中显示出来呢？
