所以我寫了一個小Hang子手遊戲，但我沒有CLUE爲什麼它不工作。通常我會問一個問題來解決問題，但我根本不知道發生了什麼，爲什麼我會遇到這個問題。沒有錯誤。爲什麼我的代碼不能按預期工作？
這裏是我的所有代碼：
public static void main(String[] args) {
Scanner sc = new Scanner (System.in);
String mysteryGuess = "hello";
String userGuess = "";
int wrongGuesses;
System.out.println("Hello and welcome to Hang Man!");
loop:
for(;;){
String[] wordAsArray = convertToStringArray(mysteryGuess);
boolean[] guessed = new boolean[mysteryGuess.length()];
for (int i = 0; i<wordAsArray.length;i++)
if(wordAsArray[i] == userGuess)
guessed[i]=true;
System.out.println("Word so far:" + visibleWord(wordAsArray,guessed));
System.out.println("What is your guess?");
userGuess = sc.next();
if (guess(userGuess,wordAsArray,guessed) == true)
System.out.println("Correct");
else
System.out.println("Incorrect");
if (didWin(guessed)==true)
break loop;
}
}
//This method creates an array version of the parameter word
//For example, if word contained the data "hello", then this method
//would return {"h", "e", "l", "l", "o"}
//Parameters: word - a single word
//Returns: an array containing each letter in word
public static String[] convertToStringArray(String word) {
String [] pWord = new String [word.length()];
for (int i = 0; i<pWord.length; i++){
pWord[i] = word.substring(i,i+1);
}
return pWord;
}
//This method determines whether the player has won the game of HangMan
//Parameters: guessed - array of boolean values
//Returns: true - if every value in guessed is true
// false - if at least one value in guessed is false
public static boolean didWin(boolean[] guessed) {
boolean bGuess = true;
loop:
for (int i = 0; i<guessed.length;i++){
if(guessed[i]==false){
bGuess = false;
break loop;
}
}
return bGuess;
}
//This method determines what portion of the hidden word is visible
//For example, if the parameters are as follows:
// wordAsArray: {"h", "e", "l", "l", "o"}
// guessed: {true, false, false, false, true}
//Then the method should return "h???o"
//Parameters: wordAsArray - the individual letters to be guessed
// guessed - array of boolean values; a true value means the corresponding letter has been guessed
//Returns: A string representing how much of the word has been guessed (unguessed letters are represented by ?'s)
public static String visibleWord(String[] wordAsArray, boolean[] guessed) {
String visibleWord="";
for(int i = 0; i<wordAsArray.length;i++){
if (guessed[i] == true)
wordAsArray[i]=wordAsArray[i];
if (guessed[i] == false)
wordAsArray[i]="?";
}
for(int i = 0; i<wordAsArray.length;i++){
visibleWord=visibleWord+wordAsArray[i];
}
return visibleWord;
}
//This method checks to see if a player has made a successful guess in the game of Hang Man
//For example, if the parameters are as follows:
// letter: "e"
// wordAsArray: {"h", "e", "l", "l", "o"}
// guessed: {true, false, false, false, true}
//Then the guessed array would be changed to:
// guessed: {true, true, false, false, true}
//And the method would return false
//Parameters: letter - the letter that the user has just guessed
// wordAsArray - an array of individual letters that are to be guessed
// guessed - array of boolean values; a true value means the corresponding letter has been guessed
//Returns: true - if letter matches an unguessed letter in wordAsArray
// false - otherwise
public static boolean guess(String letter, String[] wordAsArray, boolean[] guessed) {
boolean appearsAtLeastOnce=false;
for(int i = 0; i<wordAsArray.length;i++)
if(letter.equalsIgnoreCase(wordAsArray[i])){
guessed[i] = true;
appearsAtLeastOnce=true;
}
return appearsAtLeastOnce;
}
}
所以，當你輸入你的猜測，即使它是正確的，它會說的不正確和「字至今」不會顯示你知道它是正確的。有人請向我解釋這裏有什麼問題嗎？我相信它是一件簡單的事情，我失蹤了，但我已經在這上面待了好幾個小時。謝謝。
此外，我使用「你好」只是爲了測試。我正在尋找輸入各種字典單詞的列表。
IMO「你是比較引用類型，而不是基本類型的''==將無法正常工作」更正確的不是「你是比較字符串，而不是反對。所以'=='不會工作「。 – dorukayhan
