Here i see you are trying to find unique elements count for given string. I would suggest using HashSet for better solution.

public int getUniqueElements(String str)
{
  HashSet hSet = new HashSet<>();

  // iterate given string, hSet only adds unique elements to hashset
  for(int i = 0; i < str.length() ; i++
    hSet.add(str.charAt(i));

  return hSet.size();
}
