Regx + Java：僅將文本單獨或結尾將文本拆分為單詞並刪除標點符號

Question

我試圖將字符串拆分成單詞，但我想保留“ abc”作為單詞，並且僅在單獨出現或在單詞末尾刪除標點符號，例如

"a.b.c" --> "a.b.c"
"a.b."  --> "a.b"

例如

String str1 = "abc a.b a. .  b, , test"; should return "abc","a.b","a","b","test"

Answer 1

您可以使用：

String str1 = "abc a.b a. .  b, , test";
String[] toks = str1.split("\\p{Punct}*\\s+[\\s\\p{Punct}]*");
for (String tok: toks)
    System.out.printf(">>> [%s]%n", tok);

>>> [abc]
>>> [a.b]
>>> [a]
>>> [b]
>>> [test]
