Java在逗号(,)上拆分字符串,但在括号()之间除外

Question

我想在逗号(,)上用java分割字符串,但只要逗号(,)在某个括号之间,就不应该拆分.

例如,字符串:

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

应该产量:

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

我用的时候:

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

我最终将整个文本划分为(最后,如果)我可以看到拆分需要一个正则表达式,但我似乎无法想到如何使它完成工作.

Answer 1

你可以使用这种模式 - (不适用于嵌套的括号)

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

演示

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