我编写了这段代码，将字符串分割并存储在字符串数组中：
String[] sSentence = sResult.split("[a-z]\\.\\s+");
然而，我添加了 [a-z] 是因为我想解决缩写问题。但是我的结果显示如下：
此外，当Everett试图教他们基本数学时，他们证明了无反应
我发现我失去了在 split 函数中指定的模式。失去句号对我来说没关系，但失去单词的最后一个字母会影响它的含义。
请问有人能帮我解决这个问题吗？此外，有人能帮我处理缩写吗？例如，由于我按句号拆分字符串，我不想丢失缩写。
解析句子远非易事，即使是像英语这样的拉丁语言。像你在问题中提出的那样天真的方法会经常失败，从而在实践中被证明是无用的。
更好的方法是使用配置了正确地区设置的BreakIterator。
BreakIterator iterator = BreakIterator.getSentenceInstance(Locale.US);
String source = "This is a test. This is a T.L.A. test. Now with a Dr. in it.";
iterator.setText(source);
int start = iterator.first();
for (int end = iterator.next();
end != BreakIterator.DONE;
start = end, end = iterator.next()) {
System.out.println(source.substring(start,end));
}
要在所有情况下让正则表达式起作用可能比较困难，但为了解决你的即时问题，你可以使用反向预查：
String sResult = "This is a test. This is a T.L.A. test.";
String[] sSentence = sResult.split("(?<=[a-z])\\.\\s+");
结果：
This is a test
This is a T.L.A. test.
请注意有些缩写词并不以大写字母结尾，例如abbrev.，Mr.等。同时，也存在不以句号结束的句子！
My friend, Mr. Jones, has a new dog. This is a test. This is a T.L.A. test. Now with a Dr. in it."
间隔一行：
My friend, Mr. Jones, has a new dog.
This is a test.
This is a T.L.A. test.
Now with a Dr. in it.
