Java - 基于多个分隔符的拆分字符串

Question

I essentially want to split up a string based on the sentences, therefore (for the sake of what I'm doing), whenever there is a ! , . , ? , : , ; .

How would I achieve this with multiple items to split the array with?

Thanks!

Answer 1

String.split使用正则表达式进行拆分，因此您可以简单地：

mystring.split("[!.?:;]");

Answer 2

Guava's Splitter is a bit more predictable than String.split() .

Iterable<String> results = Splitter.on(CharMatcher.anyOf("!.?:;"))
   .trimResults() // only if you need it
   .omitEmptyStrings() // only if you need it
   .split(string);

and then you can use Iterables.toArray or Lists.newArrayList to wrap the output results how you like.

Answer 3

String.split的参数是一个正则表达式，因此您可以创建一个匹配任何这些字符的模式。

s.split("[.!:;?]");

Answer 4

您可以将String.split（String regex）方法与参数"[!.?:;]" 。
