doubt regarding patterns in regex

[archu sweet]

Hi

I just saw this in self answer test part of kathy n sierra 1.5 scjp edition....

import java.util.regex.*;
class Regex2 {
public static void main(String[] args) {
Pattern p = Pattern.compile(args[0]);
Matcher m = p.matcher(args[1]);
boolean b = false;
while(b = m.find()) {
System.out.print(m.start() + m.group());
}
}
}

Command line input: java Regex2 "\d*" ab34ef

output : 01234456


Doubt part : all i need to know is step by step explanation of output....i'm unable to understand as how "6" was included in output...
