2.个人负责模块或任务说明

本人任务: 编写主界面以及排行榜代码，玩家信息的储存，排行榜界面设计。

3.自己的代码提交记录截图

4.自己负责模块或任务详细说明

界面设计：

排行榜部分代码：
按照玩家的猜对次数进行排名，次数越少排名越高

    public Rank() throws FileNotFoundException {

        arrayList = new ArrayList<>();
        File datafile = new File("D:\\rankdata.txt");
        Scanner scanner = new Scanner(new FileInputStream(datafile));

        	User user = new User(name, count);
        	arrayList.add(user);
        }
        
        Collections.sort(arrayList, new UserComparator());
        
        for (int i = 0; i < arrayList.size(); i++) {
        	String username = arrayList.get(i).getUsername();
        	String count = arrayList.get(i).getCount() + "";
        	if (i == 0) {
        		jLabel5.setText(username);
        		jLabel10.setText(count);
                        
        	} else if (i == 1) {

5.课程设计感想

作为组长，不仅仅是负责好自己的模块，更重要的是团队的协调合作。
经过这次课设我对我自己的能力有了深刻的认识，各类代码的应用还不熟练，要能在将来继续认真的学习代码，提高自身水平。
