The empty String ("") can be found anywhere within a String...

class EmptyStrings {
  public static void main(String[] args) {
    String str = "abcde";
    for (int x = 0; x < str.length(); x++) {
      int y = str.indexOf("", x);
      System.out.println("Starting at " + x + ", empty String at " + y);
    }
  }
}

(Consider that in mathematics, for any set S, the empty set is a subset of S.)
