    which is an algorithm you want to use? What do you want the output format to be? 2 - 2 - 4 - 1 characters?

    are you considering strings of size 9 only? Otherwise please mention the format in which such strings should be displayed.

Try this one : 



  public static String getFormattedAccountNumber(String result){

        StringBuilder stringBuilder;

        if (result.length() > 3 && result.length() < 13) {

            stringBuilder = new StringBuilder(result);

            stringBuilder.insert(3, "-");

            result = stringBuilder.toString();

            if (result.length() > 6 && result.length() < 14) {

                stringBuilder = new StringBuilder(result);

                stringBuilder.insert(6, "-");

                result = stringBuilder.toString();

                if (result.length() > 13 && result.length() < 15) {

                    stringBuilder = new StringBuilder(result);

                    stringBuilder.insert(13, "-");

                    result = stringBuilder.toString();

                }

            }

        }

        return result;

    }

    I hope this will help you.



    public static String formatString(String str) {
    
    return str.substring(0, 1) + " - " + str.substring(2, 3) + " - " + str.substring(4, 7) + " - " + str.substring(8);

      With Java8 streams you can get a cleaner version...



      String s = "123456789";
      

      
AtomicInteger pos = new AtomicInteger();
      
String newS = IntStream.of(2, 2, 4, 1)
      
      .mapToObj(n -> s.substring(pos.getAndAdd(n), pos.get()))
      
      .collect(Collectors.joining(" - "));

      You can use a regular expression:



          String s = "123456789";
      
    Pattern pattern = Pattern.compile("(\d{2})(\d{2})(\d{4})(\d)");
      
    Matcher matcher = pattern.matcher(s);
      
    String formatted = matcher.find() ?
      
            matcher.group(1) + " - " + matcher.group(2) + " - " + matcher.group(3) + " - " + matcher.group(4) :
      
            "";
      
    System.out.println(formatted); // 12 - 34 - 5678 - 9

                        You can use a regular expression:



                            String s = "123456789";
                        
    Pattern pattern = Pattern.compile("(\d{2})(\d{2})(\d{4})(\d)");
                        
    Matcher matcher = pattern.matcher(s);
                        
    String formatted = matcher.find() ?
                        
            matcher.group(1) + " - " + matcher.group(2) + " - " + matcher.group(3) + " - " + matcher.group(4) :
                        
            "";
                        
    System.out.println(formatted); // 12 - 34 - 5678 - 9

FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load.
