I was working with a Integer object and I was trying to create a comma
delimited string

efficiently. Is there another way to convert integers to strings?  (The
Integer class only

allows me to set the value at construction time.)

Have ---
 BitSet recordMap ....


    for(int i = 0; i < recordMap.size(); i++) {
      if (recordMap.get(i)) {
        Integer recordNumber = new Integer(i);
        if (result.length() == 0)
          result.append(recordNumber.toString());
        else result.append(','+ recordNumber.toString());
      } // if
    } // for

Want something like this

    Integer recordNumber = new Integer();
    for(int i = 0; i < recordMap.size(); i++) {
      if (recordMap.get(i)) {
        recordNumber.setValue(i); //<------------ something like this
        if (result.length() == 0)
          result.append(recordNumber.toString());
        else result.append(','+ recordNumber.toString());
      } // if
    } // for
