使用正则表达式从Java中的圆括号内提取字符串 [英] Extracting string from within round brackets in Java with regex

问题描述

我正在尝试从圆括号中提取字符串。

假设我有 John Doe（123456789）我希望输出字符串 123456789 仅限。

I'm trying to extract a string from round brackets.
Let's say, I have John Doe (123456789) and I want to output the string 123456789 only.

我找到了此链接和此正则表达式：

I have found this link and this regex:

/\(([^)]+)\)/g

但是，我无法弄清楚如何获得想要的结果。

However, I wasn't able to figure out how to get the wanted result.

任何帮助将不胜感激。谢谢！

Any help would be appreciated. Thanks!

推荐答案

String str="John Doe (123456789)";
System.out.println(str.substring(str.indexOf("(")+1,str.indexOf(")")));

这里我正在执行字符串操作。我对正则表达式并不熟悉。

Here I'm performing string operations. I'm not that much familiar with regex.
