Length of the String without using length() method [closed]

by

  • str.toCharArray().length should work.

  • Or how about:

    str.lastIndexOf("")

    Probably even runs in constant time 🙂

  • Another one

    Matcher m = Pattern.compile("$").matcher(str);
m.find();
int length = m.end();

  • One of the dumbest solutions: str.split("").length - 1

  • Is this cheating: new StringBuilder(str).length()? 🙂
