first we have the applyGuess method that looks like this
public boolean applyGuess(char letter) {
boolean isHit = answer.indexOf(letter) != -1;
if(isHit){
hits += letter;
}else {
misses += letter;
}
this method will check if the letter we pass in this method is in the answer String and return whatever this is false or true
secondly we have the promtForGuess method
public boolean promptForGuess(){
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a letter: ");
String guessInput = scanner.nextLine();
char guess = guessInput.charAt(0);
return game.applyGuess(guess);
this method ask the user to enter a letter in keyboard and then check if the letter is correct by appealing the applyGuess method. Because we return the value of a method the method type should be same as the method we call. In the main method we call a new Prompter object and then we call the promptForGuess() method that will ask for a letter and then check if it is correct by calling the applyGuess(char letter) method and the value this method returns will go back to main to be used as we wish. It's like method are chained together to solve a problem and every single one of them solve a little bit.
