the name of the puzzle word is not hidden from the user

private String answer; private String hits; private String misses;

public Game(String answer) { this.answer = answer; hits = ""; misses = ""; }

public boolean applyGuess(char letter){

boolean isHit = answer.indexOf(letter) != -1; if (isHit){ hits += letter;

}else {
misses += letter;
}
return isHit;

}

public String getCurrentProgress(){
    String progress = "";
    for (char letter : answer.toCharArray()){
    char display = '-';
        if (hits.indexOf(letter) != 1){
            display = letter;
        }
        progress += display;

It'll help if you show a snapshot of your workspace in the future, but this one is easy enough I believe. if(hits.indexOf(letter) != -1) You have 1. That's at least one problem!:)

thank you

No problem:) It's so often something as simple as that. Sometimes a fresh pair of eyes can see it quickly.
