我正在尝试用Java创建一个Hangman游戏，我使用3个字符串来处理游戏。 randWord是从指定的单词列表数组（WORD_LIST）中随机选择的单词，randWordExt是扩展格式的randWord（例如penguin - ＆gt; p e n g u n n），guessWord是在玩家猜测时更新的String。
static String[] WORD_LIST =
{
//list of words implemented here
};
static String randWord;
static String randWordExt = "";
static String guessWord = "";
static int LIVES = 10;
这是我的主要方法，问题是，当单词完全解决时，while循环不会退出。因此，永远不会显示最终消息。它完美地循环，猜测作品，但是当单词被解决时，它不会退出循环或显示最终的消息。
public static void main(String[] args) {
boolean running = true;
Scanner input = new Scanner(System.in);
generateWord();
System.out.println("You have " + LIVES + " lives to guess the word! \n" + guessWord);
while(running){
guessLetter(input.next().charAt(0));
if(guessWord == randWordExt){
running = false;
} else {
System.out.println(guessWord);
System.out.println("Lives left: " + LIVES);
}
}
input.close();
System.out.println("The word was " + randWord + ", you guessed it in " + " moves!");
}
generateWord方法：
public static void generateWord(){
randWord = WORD_LIST[(int)(Math.random() * 87)];
for(int i = 0; i < randWord.length(); i++){
guessWord = guessWord + "_ ";
}
for(int i = 0; i < randWord.length(); i++){
randWordExt = randWordExt + randWord.charAt(i) + " ";
}
}
最后是guessLetter方法：
public static void guessLetter(char letter){
boolean changed = false;
for(int i = 0; i < randWordExt.length(); i++){
if(!(guessWord.charAt(i) == letter)){
if(randWordExt.charAt(i) == letter){
guessWord = guessWord.substring(0, i) + letter + guessWord.substring(i + 1);
changed = true;
} else if (randWordExt.charAt(i) != letter && i == randWordExt.length() - 1 && changed == false){
LIVES -= 1;
System.out.println("\'" + letter + "\'" + " is not in the word!");
}
} else {
System.out.println("\'" + letter + "\'" + "has already been guessed!");
}
}
}
