Split a string into array every 11th char

[isaac.flaum]

I have this:
String str = "000000000001111111111122222";
String[] array = new String[3]';

I would like a way to split str every 11 characters into array so that i would have:
array[0] = "00000000000";
array[1] = "11111111111";
array[2] = "22222";

I tried using the split method but that kept inserting pesky [] characters. Any idea how to do this?

There are many ways to make this.

You could use a StringBuilder, or String.substring or with split and a Regex e.g. with

		String str = "000000000001111111111122222";
		String[] array = str.split("(?<=\\G.{11})");
