用于获取仅评估字符串一部分的行的正则表达式，java

Question

I'm trying to find the regular expression to match only a part of the pattern

For an example text is :

GoodClass.NiceMethod
BadClass.NiceMethod
Badclass2.NiceMethod
Verybadclass.NiceMethod
GoodClass.NiceMethod
BadClass.NiceMethod
Badclass2.NiceMethod
GoodClass.NiceMethod

how can I get all lines where 'NiceMethod' does not follow 'GoodClass'

Answer 1

您可以使用负面回顾：

String regex = "(?<!GoodClass\\.)\\bNiceMethod\\b";
