System.out.print... problem

So here is the snapshot of my workspaces: https://w.trhou.se/nzxiv6oj5q

Problem is that even though in my Main class I have:

        if (prompter.promptForGuess()) {
            System.out.println("You've guessed");
        } else {
            System.out.println("You've not guessed");
        }

and in Prompter class I have"

public void displayProgress() {
    System.out.printf("You have %d tries left to solve: %s%n",
            game.getRemainingTries(),
            game.getCurrentProgress());
}

when I run the code and I type in letter and press enter(doesn't matter if the letter is in the answer), console shows:

Enter a letter:
g Enter a letter:

meaning, that after "g" it doesn't display the text "You've guessed"/"You've not guessed", neither it displays the progress text "You have %d tries left to solve: %s%n".

Please, help me.

You're actually asking the prompter to ask for a letter 2 times before displaying the progress

prompter.promptForGuess(); // here you're asking for a letter the first time

if (prompter.promptForGuess()) {  // here you're asking the prompter for a letter again
    System.out.println("You've guessed");
} else {
    System.out.println("You've not guessed");
}

Thank you so much for the answer :) That's so obvious now, I fail to understand how could I not see it before.
