Java相当于Perl的///运算符？ [英] Java equivalent of Perl's s/// operator?

问题描述

我有一些代码，我正在从Perl转换为Java。它大量使用正则表达式，包括 s /// 运算符。我已经使用Perl很长一段时间了，我仍然习惯于Java的做事方式。特别是，Strings似乎更难以使用。有没有人知道或者有一个完全实现 s /// 的Java函数？所以它可以处理这样的事情，例如：

I have some code that I'm converting from Perl to Java. It makes pretty heavy use of regular expressions, including the s/// operator. I've been using Perl for a long time and am still getting used to the Java way of doing things. In particular, Strings seem more difficult to work with. Does anyone know of or have a Java function that fully implements s///? So that it could handle something like this, for example:

$newString =~ s/(\bi'?\b)/\U$1/g;

（也许不是一个很好的例子，但你明白了。）谢谢。

(Maybe not a great example, but you get the idea.) Thanks.

推荐答案

看看String的 replaceAll（...）方法。请注意，Java不支持 \ U （大写）功能。

Have a look at String's replaceAll(...) method. Note that Java does not support the \U (upper-case) feature.
