我正在嘗試創建一個 Magic 8 Ball 程序：使用初始值設定項列表將所有響應存儲在字符串數組中。使用隨機對象（范圍在 0 到 19 之間）生成響應的隨機數。提示用戶輸入問題。使用隨機數來訪問并顯示相應的響應。詢問用戶是否想問另一個問題（使用 do-while 循環）。只要用戶說“是”，代碼就應該重復。我在執行第 5 步時遇到問題。所有其他步驟我都能夠很好地完成，但是當我輸入“是”時，它不會讓我問另一個問題，而是會跳過該問題并給我答案。這是我到目前為止所擁有的： //initializing variables  int stop = 0;  String otherQ,q;  //initializing array  String[] responses = {  "It is certain.",  "It is decidedly so.",  "Without a doubt.",        "Yes - definitely.",  "You may rely on it.",  "As I see it, yes.",  "Most likely.",  "Outlook good.",  "Yes.",        "Signs point to yes.",  "Reply hazy, try again.",  "Ask again later.",  "Better not tell you now.",  "Cannot predict now.",  "Concentrate and ask again.",        "Don't count on it.",  "My reply is no.",  "My sources say no.",  "Outlook not so good.",     "Very doubtful."};  //creates objects  Scanner scan = new Scanner (System.in);  Random rn = new Random();  //input  //THIS IS WHERE I AM HAVING A PROBLEM.  do {      System.out.print("What is your question? ");      q = scan.nextLine();       System.out.println(responses[rn.nextInt(19)]);  //method caller  while (stop == 0) {        System.out.print("Would you like to ask another question? (Answer yes or no): ");        otherQ = scan.next();         if (otherQ.equalsIgnoreCase("yes")){          break;        }else if (otherQ.equalsIgnoreCase("no")){           stop = 1;        }     }  } while (stop == 0);我的預期結果是：    What is your question? Question goes here       As I see it, yes.      Would you like to ask another question? (Answer yes or no): yes      What is your question? Cannot predict now.        Would you like to ask another question? (Answer yes or no): 我用上面的代碼得到的結果：    What is your question? Question goes here    It is certain.    Would you like to ask another question? (Answer yes or no): yes    What is your question? Question goes here    Would you like to ask another question? (Answer yes or no): no非常感謝您對我的幫助！
