I have to make a loop taking a users input until “done” is entered

Question

I\'m trying to make an ArrayList that takes in multiple names that the user enters, until the word done is inserted but I\'m not really sure how.

Answer 1

I would probably do it like this -

public static void main(String[] args) {
  System.out.println("Please enter names seperated by newline, or done to stop");
  Scanner scanner = new Scanner(System.in);     // Use a Scanner.
  List al = new ArrayList();    // The list of names (String(s)).
  String word;                                  // The current line.
  while (scanner.hasNextLine()) {               // make sure there is a line.
    word = scanner.nextLine();                  // get the line.
    if (word != null) {                         // make sure it isn't null.
      word = word.trim();                       // trim it.
      if (word.equalsIgnoreCase("done")) {      // check for done.
        break;                                  // End on "done".
      }
      al.add(word);                             // Add the line to the list.
    } else {
      break;                                    // End on null.
    }
  }
  System.out.println("The list contains - ");   // Print the list.
  for (String str : al) {                       // line
    System.out.println(str);                    // by line.
  }
}
