做while循環嗎？ （JAVA）

Question

我正在做一個實質上是電影測驗的程序，從可以正常工作的文本文件中讀取電影標題/發行日期/類型/毛利率，問題是可以隨時退出以使while循環正常工作用戶兩次都提示時（在每個問題之后以及最后）都沒有輸入no，非常感謝任何建議/提示！

這是我所擁有的：

private static void movieQuiz (Movies[] movieRecord){

    int score = 0; 
    Scanner keyboard = new Scanner (System.in);
    String userChoice;

    System.out.println("You have selected the Movie Quiz! The instructions"
            + " are as follows: The program will output \nthe title of one of "
            + "the highest grossing films of all time, your job is "
            + "to guess which year \nit was released. A point will be added "
            + "to your score for each correct answer, and your total \npoints will"
            + " display at the end or until you want to give up. Have fun and"
            + " good luck!\n");
    int test = 0;
    loadMovies(movieRecord);
    System.out.println("Are you ready to begin?");
    userChoice = keyboard.next();

    //do this if they want to run it again
    do {
      for (int count = 0; count <= movieRecord.length-1; count++) {
        System.out.println("Movie #" + (test+1) + ": " + movieRecord[count].movieTitle);
        System.out.println("Guess the year");
        int guess = keyboard.nextInt();

          if (guess == movieRecord[count].releaseYear){
            System.out.println("DING DING DING! (+1) \n" );
            score++;
          }

          else {
            System.out.println("Wrong (+0) \n");
          }

          System.out.println("Continue? (Currently on #" + (1 + test) + " out of "
          + movieRecord.length + ")");
          userChoice = keyboard.next();

          test++;

      }
    }   while (userChoice.charAt(0) == 'y');

      //display if they type 'no' at any time, ending the program
      System.out.println("Total Score is: " + score + " out of " + movieRecord.length);
        System.out.println("AGAIN? yes/no?");
        userChoice = keyboard.next();
}

Answer 1

休息一下 !!!!

您需要了解Java中的中斷，並在代碼中實現。

你可以試試這個嗎？

     int score = 0; 
        Scanner keyboard = new Scanner (System.in);
        String userChoice;

        System.out.println("You have selected the Movie Quiz! The instructions"
                + " are as follows: The program will output \nthe title of one of "
                + "the highest grossing films of all time, your job is "
                + "to guess which year \nit was released. A point will be added "
                + "to your score for each correct answer, and your total \npoints will"
                + " display at the end or until you want to give up. Have fun and"
                + " good luck!\n");
        int test = 0;
        loadMovies(movieRecord);
        System.out.println("Are you ready to begin?");
        userChoice = keyboard.next();

        //do this if they want to run it again
        do {
          for (int count = 0; count <= movieRecord.length-1; count++) {
            System.out.println("Movie #" + (test+1) + ": " + movieRecord[count].movieTitle);
            System.out.println("Guess the year");
            int guess = keyboard.nextInt();

              if (guess == movieRecord[count].releaseYear){
                System.out.println("DING DING DING! (+1) \n" );
                score++;
              }

              else {
                System.out.println("Wrong (+0) \n");
              }

              System.out.println("Continue? (Currently on #" + (1 + test) + " out of "
              + movieRecord.length + ")");
              userChoice = keyboard.next();

              if(userChoice.charAt(0) == 'n'){
              //display if they type 'no' at any time, ending the program
              System.out.println("Total Score is: " + score + " out of " + movieRecord.length);
                System.out.println("AGAIN? yes/no?");
                userChoice = keyboard.next();
                if (userChoice.charAt(0) == 'n')
                    break;
              }

              test++;

          }
        }   while (userChoice.charAt(0) == 'y');

    }
