问题描述
例如，我要从文本文件中提取文本String，我需要这些词来形成数组.但是，当我执行所有这些操作时，有些单词以逗号(，)或句号(.)结尾，甚至在其上附加了括号(这完全是正常现象).
For example I'm extracting a text String from a text file and I need those words to form an array. However, when I do all that some words end with comma (,) or a full stop (.) or even have brackets attached to them (which is all perfectly normal).
我想做的就是摆脱那些角色.我一直在尝试使用Java中的预定义String方法来做到这一点，但我还是无法解决.
What I want to do is to get rid of those characters. I've been trying to do that using those predefined String methods in Java but I just can't get around it.
推荐答案
使用:
String str = "whatever";
str = str.replaceAll("[,.]", "");
replaceAll 使用正则表达式.这个:
[,.]
...查找每个逗号和/或句点.
...looks for each comma and/or period.
