Answer 1

您可以在java中使用下面的代码片段来获得所需的输出。

String str = s.replaceAll("\\n", "~")
.replaceAll("~\s", System.lineSeparator())
.replaceAll("~", "");

Answer 2

虽然不是java，但这里是regex替换(python(的证明：

>>> s = '"Link">https://tsad.rs/2RBWI5E\n\n    By Tom Westbrook\n    sjda, asd 14 (sda) - sad dsad asd lower on\nTuesday, but gains in riskier currencies were capped as traders\nfretted adlaj \nladsadj \n   Available to our procedure.JPY='
>>> r = re.sub(r"s*\n+s+", "n", s)
>>> r = re.sub(r"s*\n", " ", r)                                                                                                                                               >>> print(r)

对于java，它应该是这样的：

sentences[i] = sentences[i].replaceAll("s*\n+s+", "n").replaceAll("s*\n", " ");
