CodeEval为什么会标记我的解决方案（LongestLines）错误？

Question

所以，我做了CodeEval'Longest Lines'的问题，它可以正常工作，我可以设计任何输入数据。当我上传到CodeEval时，它说它是错误的。

因为这是一个“中等”的问题，所以没有提供输入数据。一些System.out.println废话后，我得到了测试数据，我的解决方案似乎工作。我是否错过了某些东西，或者CodeEval有问题吗？

我的解决方案：

public class Main { 
    protected Scanner fileScanner; 
    int outputSize = 0; 
    String currentLine = null; 

    public Main(String filename) 
    { 
     try { 
      File file = new File(filename); 
      fileScanner = new Scanner(file); 
     } catch (FileNotFoundException e) { 
      System.err.println("Invalid file input."); 
     } 
    } 

    public void loadNextLine() { 
     if (outputSize > 0) 
     { 
      currentLine = fileScanner.nextLine(); 
     } 
     else 
     { 
      outputSize = Integer.parseInt(fileScanner.nextLine()); 
     } 
    } 

    public void process() { 
     List<String> fileContents = new ArrayList<String>(); 

     while (fileScanner.hasNext()){ 
      loadNextLine(); 
      fileContents.add(currentLine); 
     } 

     fileContents = bubbleSort(fileContents); 

     for (int i=0; i<outputSize; i++){ 
      System.out.println(fileContents.get(i)); 
     } 
    } 

    /** 
    * <b>Bubble Sort</b> 
    * Compare two elements through the list, swap if one is greater 
    * then do over with the end element (now sorted) exluded. 
    * Repeat until sorted. 
    */ 
    private List<String> bubbleSort(List<String> list){ 
     for (int lastIndex=list.size()-1; lastIndex >= 0; lastIndex--){ 
      for (int i=0; i<lastIndex; i++){ 
       String first = list.get(i); 
       String second = list.get(i+1); 

       //Swap? 
       if (first.length() < second.length()){ 
        list.set(i, second); 
        list.set(i+1, first); 
       } 
      } 
     } 

     return list; 
    } 

    public void start() 
    { 
     while (fileScanner.hasNext()) { 
      loadNextLine(); 
      process(); 
     } 
    } 

    public static void main (String[] args) throws IOException { 
     Main problem = new Main(args[0]); 
     problem.start(); 
    } 
} 

我从CodeEvalprintln S的结果，第一输出我的有序列表则需要对问题的第一n。好像是吧？

注意

• 我不控制对象Main的选择，这是一个CodeEval结构。
• 这是posted在代码审查，但封闭，题外话

Answer 1

它看起来像CodeEval有一些无证的限制，所需资源需要在某些参数内。在这种情况下可能是执行时间。

Answer 2

看起来你忘了删除从主构造System.out.println()调用。
