Java在逗号(，)上分割字符串，括号之间的除外() [英] Java split string on comma(,) except when between parenthesis ()

问题描述

我想在逗号(，)上的java中拆分字符串，但是只要逗号(，)位于括号之间，就不应拆分.

I would like to split a string in java on a comma(,) but whenever the comma(,) is in between some parenthesis, it should not be split.

例如字符串:

"life, would, (last , if ), all"

应该产生:

-life
-would
-(last , if )
-all

当我使用时:

String text = "life, would, (last , if ), all"
text.split(",");

我最终将整个文本除以(最后一个if)，我可以看到split使用了一个正则表达式，但是我似乎想不出如何使它完成工作.

I end up dividing the whole text even the (last , if ) I can see that split takes a regex but I can't seem to think of how to make it do the job.

推荐答案

您可以使用此模式-(不适用于嵌套括号)

you could use this pattern - (not for nested parenthesis)

,(?![^()]*\))

演示

,               # ","
(?!             # Negative Look-Ahead
  [^()]         # Character not in [()] Character Class
  *             # (zero or more)(greedy)
  \             # 
)               # End of Negative Look-Ahead
)
