You can write an toComaString function to do that easily.
This is one I came up:
public static String toCommaString(int i){
String s=String.valueOf(i);
int l=s.length();
if(l <= 3) return s;
StringBuffer sb=new StringBuffer(s);
int ll=l-3;
while (ll>0){
sb.insert(ll,',');
ll=ll-3;
}
return sb.toString();
}

A better way to do it is to use NumberFormat, taking into account the Locale.
