我的代码：

Quiz newquiz = new Quiz(); 
    List<String> newArray = new ArrayList<String>(); 
    Map<Integer, String> newquizmap = new HashMap<Integer, String>(); 
    BufferedReader BufferedReader = new BufferedReader(new FileReader('file.txt')); 
    String line = null; 

    while ((line = BR.readLine()) != null) { 
     String nuquiz[] = line.split(" "); 
     BufferedReader.readLine(); 

     newquiz.newquestionid = Integer.parseInt(parts[0]); 



      lines.add(line); 
       newquizmap.put(newquiz.newquestionid, newArray.toString()); 


      line = BufferedReader.readLine(); 

      System.out.println(newquizmap); 
     } 

    } BR.close(); 

我知道这是不对的，我不即使认为它很接近，但我真的很困难，这有人可以给我任何帮助吗？

编辑：

  Quiz newquiz = new Quiz(); 
    List<String> newArray = new ArrayList<String>(); 
    Map<Integer, String> newquizmap = new HashMap<Integer, String>(); 
    BufferedReader BufferedReader = new BufferedReader(new FileReader('file.txt')); 
    String line = null; 

    while ((line = BR.readLine()) != null) { 
     String nuquiz[] = line.split(" "); 
     BufferedReader.readLine(); 

     newquiz.newquestionid = Integer.parseInt(parts[0]); 



      lines.add(line); 
       newquizmap.put(newquiz.newquestionid, newArray.toString()); 


      line = BufferedReader.readLine(); 

      System.out.println(newquizmap); 
     } 

    } BR.close(); 

尝试这个代码，它似乎充满了每一个值每一个地图的关键？

一种方法是将java对象用作散列表值。创建一个新的类来包含以下属性（修改，以处理所有的问题用例）：

private String questionId; //This will hold question Id - TF  
private String question; //This will hold the Question - Because an ArrayList is an indexed collection, you can access its elements using a subscript. 
    private List<String> choices; //This will hold the choices - Private Inner Public Internal 
    private Integer selectedChoice; //This will hold the answer 

包括参数的构造函数和类中的其他必要方法。

解析文件，遍历内容，创建这个新类的一个对象，并添加hashmap，其中“id”作为键和“pojo对象”作为值。

注：请更正Java代码的几个其他问题（格式，编码就像变量名标准大写，QuestionSet，由于输出开始..等）
