如何删除Java中单个单词后面的所有标点符号？ [英] How do I remove all punctuation that follows a single word in Java?

问题描述

我需要删除一个单词后面的标点符号。例如， word？！应更改为 word 和 string：应更改为 string 。

I need to remove punctuation following a word. For example, word?! should be changed to word and string: should be changed to string.

编辑：算法应该只删除字符串末尾的标点符号。字符串中的任何标点都应该保留。例如，不会; 应该变成不会。

The algorithm should only remove punctuation at the end of the String. Any punctuation within the String should stay. For instance, doesn't; should become doesn't.

推荐答案

您可以使用正则表达式修改字符串。

You could use a regex to modify the string.

String resultString = subjectString.replaceAll("([a-z]+)[?:!.,;]*", "$1");

我所知道的单词'在最后，它被用作标点符号。所以这个正则表达式适合你。

There are no "words" that I know of where ' is at the end and it is used as a punctuation. So this regex will work for you.
