Java. How can I split a string with multiple spaces on every nth space?

Question

Here's a sample string which I intend to split into an array:

Hello My Name Is The Mighty Llama

The output should be:

Hello My
Name Is
The Mighty
Llama

The below splits on every space, how can I split on every other space?

String[] stringArray = string.split("\\s");

Why not just split it and get the alternate index from the resulting array ? — Adarsh, Dec 06 '13 at 17:01

You could do:

String[] stringArray = string.split("(?<!\\G\\S+)\\s");

I would use `\S+` instead of `\w+`. – arshajii Dec 06 '13 at 16:55

While this is possible to use split to solve it like this one I strongly suggest using more readable way with Pattern and Matcher classes. Here is one of examples to solve it:

String string="Hello My Name Is The Mighty Llama";
Pattern p = Pattern.compile("\\S+(\\s\\S+)?");
Matcher m = p.matcher(string);
while (m.find())
    System.out.println(m.group());

output:

Hello My
Name Is
The Mighty
Llama
