Is there a way to split strings with String.split() and include the delimiters?

Suppose I have the following sentences-

What is your name? My name is Don. You are so nice!

I want the output by java as follows

What is your name?
My name is Don.
You are so nice!

I used the java split() method. but it split without the delimiters. i used split("[\\.!?]")

@Nick, that question asks how to split on non alphanumerics, which is not what the OP wants. — Qwerky, Feb 18 '11 at 10:26

This does the trick:

split("(?<=[.?!])");

(Adapted from this great answer)

that doesn't remove the space, which I believe the OP wants. – Qwerky Feb 18 '11 at 10:36
@Qwerky - The requirement was: split at delimiters (punctuation marks) and keep them. But getting rid of the space(s) in one go, like you showed, is an nice idea (bonus). – Andreas Dolk Feb 18 '11 at 10:41

You should split on whitespace, with a lookbehind on the '.!?' characters.

String s = "What is your name? My name is Don. You are so nice!";

String[] tokens = s.split("(?<=[\\.\\!\\?])\\s");

for (String t : tokens) System.out.println(t);
