String Pattern Question - Core Java (repeatSeparator) -

write java function such given 2 strings, word , separator, return big string made of count occurences of word, separated separator string.

repeatseparator("word", "x", 3) → "wordxwordxword"         repeatseparator("this", "and", 2) → "thisandthis"          repeatseparator("this", "and", 1) → "this"         

my code below not working

public string repeatseparator(string word, string sep, int count) {             if(count == 1) {                return word;             }         if(count > 1) {                (int = 0; < count-1; i++){                     word = word + sep + word;                    }            }                   return word;                          } 

example output ::

                                   expected         run                  result         repeatseparator("word", "x", 3) → "wordxwordxword" "wordxwordxwordxword" x     

the below function should need:

public string repeatseparator(string word, string sep, int count) {         stringbuffer buffer = new stringbuffer();      while (count > 0) {         buffer.append(word);         count--;         if (count > 0) {             buffer.append(sep);         }     }      return buffer.tostring();                            }
