I am not sure about what our promptForGuess() method will do

public void promptForGuess(){
   Scanner scanner = new Scanner(System.in);
    System.out.print("Enter a character:  ");
    String guessInput= scanner.nextLine();
  }

I was wondering if this code String guessInput= scanner.nextLine(); stores the input that the user of our app enterred in this code System.out.print("Enter a character: ");

Hi there,

Yes, and no.

The first line, System.out.print("Enter a character: "); merely prompts the user - it just outputs something to the screen that the user can read.

The next line, String guessInput= scanner.nextLine(); does both the things you mention. The part to the right of the equals sign reads what the user has entered on the keyboard. And the part to the left stores that input in the string variable named guessInput.

So, the end result of the code is as you expected, but the two tasks you mention were carried out by one line of code, i.e. getting user input and storing that input.

I hope that helps.

Steve.
