正则表达式替换字符串和特定字符串

String a = "This is a book! I am a boy. He is a good man. My friend Mrs. Roy is good man. He is nice person. Miss. Star is my friend.";
String b = Pattern.compile("([a-zA-Z]+)([.!?])( )([A-Z]+)",Pattern.CASE_INSENSITIVE).matcher(a).replaceAll("$1$2 →$4");

The result is :

结果是：

This is a book! →I am a boy. →He is a good man. →My friend Mrs. →Roy is good man. →He is nice person. →Miss. Star is my friend.

If you desire to match a well written sentences in your test you should first match Uppercase or Lowercase , then anything that is not a quotation and then one of them. And then not Match special groups Like Dr, Mr , Mrs and etc.

如果你想在你的测试中匹配一个写得好的句子，你应该首先匹配大写或小写，然后匹配任何不是引用然后其中一个。然后不匹配像博士，先生，夫人等特殊群体。

(([^.!?]|(?<=Dr|Mr|Mrs|\b[A-Za-z]|\s)[.!?])*[\.!?])

the explanation :

说明 ：

1st Capturing Group

第一捕获组

(([^.!?]|(?<=Dr|Mr|Mrs|\b[A-Za-z]|\s)[.!?])*[\.!?])

2nd Capturing Group

第二捕获小组

([^.!?]|(?<=Dr|Mr|Mrs|\b[A-Za-z]|\s)[.!?])*

*

Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy) A repeated capturing group will only capture the last iteration. Put a capturing group around the repeated group to capture all iterations or use a non-capturing group instead if you're not interested in the data 1st Alternative

量词 - 在零和无限时间之间匹配，尽可能多次，根据需要返回（贪婪）重复捕获组将仅捕获最后一次迭代。如果您对数据不感兴趣，请在重复组周围放置捕获组以捕获所有迭代或使用非捕获组

[^.!?]

Match a single character not present in the list .!?

匹配列表中不存在的单个字符。！？

2nd Alternative

第二种选择

(?<=Dr|Mr|Mrs|\b[A-Za-z]|\s)[.!?]

Positive Lookbehind

积极的看后

(?<=Dr|Mr|Mrs|\b[A-Za-z]|\s)

Assert that the Regex below matches

断言下面的正则表达式匹配

1st Alternatives

第一选择

Dr|Mr|Mrs

Dr matches the characters Dr,Mr,Mrs literally (case sensitive)

博士匹配字符Dr，Mr，Mrs字符（区分大小写）

2th Alternative

第二种选择

 \b[A-Za-z]\s

And both the groups

两个小组

[.!?]

Match a single character present in the list .!?

匹配列表中的单个字符。！？
