Regular Expression with java

Here is a string of length 60 which in turn could be divided into 10 individual strings of 6 characters each . I want to divide this(6 character string) into a pattern of 3-2-1. I want to use Regular expression. jdk is 1.4.2
String regex = "((\\w|\\s){3})((\\w|\\s){2})((\\w|\\s){1})"
The string could be made of white spaces or characters
Here is the java class
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class RegexTest {
private static String input;
private static Pattern pattern;
private static Matcher m;
public static void main( String args []) {
String regex = "((\\w|\\s){3})((\\w|\\s){2})((\\w|\\s){1})";
input = "ABCDEFGHIJKLMNOPQURSTUVWXYZ" ;
pattern = Pattern.compile(regex);
m = pattern.matcher(input);
while (m.find())
{
System.out.println(m.group(0));
System.out.println(m.group(1));
System.out.println(m.group(2));
System.out.println(m.group(3));
}
}
}

The expected result is
ABCDEF
ABC
DE
F

Thanks in advance,

Capturing groups are numbered according to the order in which their opening parentheses appear. You should have made those innermost groups non-capturing, like this:But a character class would be much more efficient than alternation there:

Thank you, it works.
