Answer 1

I think you may be best off using the split method on your string (mystring.split(' ')) and treating the two cases separately. Regex can be hard to maintain and read if you're going to have multiple people updating the code.

if (word.charAt(0) == '#') {
  if (word.length() == 1) {
    // use next word
  } else {
    // just use current word without the #
  }
}
