不使用捕获组,您可以使用前瞻((?= ... )
业务).
Without using capture groups, you can use lookahead (the (?= ... )
business).
java\s?[^A-Z]*(?=\.[A-Z])
应该可以捕获您想要的所有内容.分解如下:
java\s?[^A-Z]*(?=\.[A-Z])
should capture everything you're after. Here it is broken down:
java //Literal word "java"
\s? //Match for an optional space character. (can change to \s* if there can be multiple)
[^A-Z]* //Any number of non-capital-letter characters
(?=\.[A-Z]) //Look ahead for (but don't add to selection) a literal period and a capital letter.
