我已經使用 java 幾個星期了，想嘗試制作我的第一個小游戲。我所擁有的一切都工作正常，直到我嘗試添加再次播放功能?？雌饋硭皇翘^了底部的一小部分代碼，我不明白為什么。我嘗試過移動代碼的不同部分，但無法弄清楚為什么它不起作用。public static void main(String[] args) {    Scanner scan = new Scanner(System.in);    System.out.println("You have 10 tries to correctly guess a random number between 1 and 10. Good luck! \n"            + "After you have entered a number, press ENTER to see if you won.");    boolean play;       play = true;   do    {            int tries = 10, triesLeft = 0, triesUsed = 0;       String YorN;     do    {        System.out.print("\nEnter A Number: ");        int numInp = scan.nextInt();            int randomNumber = (int)(Math.random()*9) + 1;        System.out.println("The number was " + randomNumber);        if(numInp == randomNumber) {            System.out.println("\nYou Win! Great job.");            triesLeft = --tries;            triesUsed = 10 - triesLeft;            tries = -1;        } else {            System.out.println("Try Again...");            tries --;        }    }    while( tries > 0);    String playAgain = (" Feel free to play again soon!");    if(tries == 0) {        System.out.println("\nOut of tries :(   You lose loser  " + playAgain);    }    if(tries == -1) {    System.out.println("\nYou used " + triesUsed + " tries and had "            + triesLeft + " tries left! :)" + playAgain);    }    System.out.print("\nDo you want to play again? Y or N?");    YorN = scan.nextLine();    if (YorN == ("Y") || YorN == ("y"))    {        play = true;    }    else if (YorN == ("N") || YorN == ("n"))    {        play = false;    }    else {}   } while(play = true);   if (play = false){       System.out.println("\nGood Bye");    }}當我運行代碼時，這個系統似乎沒有做任何事情：YorN = scan.nextLine();    if (YorN == ("Y") || YorN == ("y"))    {        play = true;    }    else if (YorN == ("N") || YorN == ("n"))    {        play = false;    }    else {}這是我運行時看到的內容：你贏了！做得好。您已經嘗試了 5 次，還剩 5 次嘗試！:) 很快就可以再次玩了！你想再玩一次嗎？是還是否？輸入號碼：它沒有給我一個應該輸入 y 或 n 的位置。如果有人知道為什么我會非常感謝你的幫助
