Split a string by space or by \n

I would like to split a string by two delimeters: a space (" ") or a new line (\n).

What I've tried:

message.split("\\r?\\n? ");

It does split by space, but not by \n, turning:

The way I see it we got two options. Option one, we take the easy way
out. It's quick and painless. I'm not a fan of option one. Option two,
We fight.

into:

[The, way, I, see, it, we, got, two, options., Option, one,, we, take, the, easy, way, out., It's, quick, and, painless., I'm, not, a, fan, of, option, one.Option, two,, We, fight.]

Note that one.Option is one cell in the array.

From the comments, try "\\s+" to split on one or more whitespace characters. This includes space, tab, newline, carriage-return, line-feed, etc so it might be a bit too large a hammer for what you want.

final String message = "The way I see it we got two options. Option one, we take the easy way\n" +
        "out. It's quick and painless. I'm not a fan of option one. Option two,\n" +
        "We fight.";
System.out.println(String.join(", ", message.split("\\s+")));

Produces

The, way, I, see, it, we, got, two, options., Option, one,, we, take, the, easy, way, out., It's, quick, and, painless., I'm, not, a, fan, of, option, one., Option, two,, We, fight.

"\\r?\\n? "

This tells it to split by either "\\r\\n " or "\\n " or "\\r " or " ", but never by "\\r" or "\\n" or "\\r\\n" without the space.

The following will tell it to split by any consecutive combination of "\\r", "\\n" and " " with at least one character:

"[\\r\\n ]+"
