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

Why is it required for the promptForGuess variable?

1 Answer

I am not sure what you mean by "promptForGuess variable". In the video at around time 4:37, I saw this code that I think you are referring to:

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

My advice is to use the website's workspaces and start typing and follow along with the code. Here's an example from my workspace: https://teamtreehouse.com/workspaces/16125232
