Hello I would like to use DecimalFormat to display:
8392472 as
839 24 72
I have tried
DecimalFormat dc = new DecimalFormat("000 00 00");
return dc.format(number);
I have also tried "### ## ##"

I don't think you can do that with a DecimalFormat because your spaces are not group or decimal separators.
The simple way would be to simply use a string:
int number = 8392472;
String s = String.valueOf(number);
String formatted = s.substring(0, 3) + " "
+ s.substring(3, 5) + " "
+ s.substring(5, 7);

I think easiest way to achieve this is as below.
public static void main(String[] args) {
int number = 8392472;
StringBuilder sb = new StringBuilder(String.valueOf(number))
.insert(3," ")
.insert(6," ");
System.out.println(sb.toString());
}

This is slightly less efficient as it will involve copying the underlying array twice - that will probably not make a noticeable difference in most cases. – assylias Apr 15 '13 at 13:33

Any phone number with leading 0's will mess up. Used to be, in the US and Canada, all area codes began with the digit 2-9 and had 0 or 1 as the 2nd digit. The 2nd digit part isn't true any more. I don't know if the first digit can be 0 now. – Lee Meador Jun 24 '13 at 20:41
