Prompt For Guesses: What purpose does the Console object serve?

public boolean promptForGuess() {
  // promptForGuess is the name of this method that you are writing, creating

  Console console = System.console();
  // Console is something Java already wrote for people to use to get input and print output.
  // There are other ways to get input from the user, but this is the simplest for beginners.

  String guessAsString = console.readLine("Enter a letter: ");
  // console reads the input the user types in and stores it inside a string variable (guessAsString)

  char guess = guessAsString.charAt(0);
  // this line gets the 1st letter of the input. So if the user typed "No", guess is "N".
  // if user typed in "yes", then guess is "y"
  // if user typed in "Apple", then guess is "A"

  return mGame.applyGuess(guess);
  // this checks to see if the letter was in the hangman word
}

// he calls the method later in the video in another piece of code
public static void main(String args[]){
 ...
    Prompt prompter = ...;
    // create a prompter object

    boolean isHit = prompter.promptForGuess();
    // call the promptForGuess method that we wrote and store the result in variable isHit
