如何在Java中填充字符串？ [英] How can I pad a String in Java?

问题描述

是否有一些简单的方法可以在Java中填充字符串？

Is there some easy way to pad Strings in Java?

看起来像某些类似于StringUtil的API，但我找不到任何东西这样做。

Seems like something that should be in some StringUtil-like API, but I can't find anything that does this.

推荐答案

Apache StringUtils 有几种方法： leftPad ， rightPad ， 中心 和 重复 。

Apache StringUtils has several methods: leftPad, rightPad, center and repeat.

但请注意 - 正如其他人在此答案 - String.format（）和JDK中的 Formatter 类是更好的选择。在公共代码上使用它们。

But please note that — as others have mentioned and demonstrated in this answer — String.format() and the Formatter classes in the JDK are better options. Use them over the commons code.
