Regx + Java：將文本拆分爲單詞並僅在單獨或結尾時刪除標點符號

Question

我想將一個字符串拆分爲單詞，但我想保留「abc」作爲單詞，並刪除標點符號僅當它是單獨的或在詞的末尾時 例如

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

e.g

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]
