2.我的負責模塊或任務說明

本人任務: 編寫主界面以及排行榜代碼，玩家信息的儲存，排行榜界面設計。

3.本身的代碼提交記錄截圖

4.本身負責模塊或任務詳細說明

界面設計：

排行榜部分代碼：
按照玩家的猜對次數進行排名，次數越少排名越高

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;

import javax.swing.JFrame;
/**
 *
 * @author spring
 */
public class Rank extends javax.swing.JFrame {
private ArrayList<User> arrayList;
    /**
     * Creates new form paihang
     * @throws FileNotFoundException 
     */
    public Rank() throws FileNotFoundException {    
        initComponents();
        arrayList = new ArrayList<>();
        File datafile = new File("D:\\rankdata.txt");
        Scanner scanner = new Scanner(new FileInputStream(datafile));
        while (scanner.hasNextLine()) {
            String string = scanner.nextLine();
            String[] strings = string.split(" ");
            String name = strings[0];
            int count = Integer.parseInt(strings[1]);
            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) {
                jLabel8.setText(username);
                jLabel11.setText(count);
            } else if (i == 2) {
                jLabel7.setText(username);
                jLabel12.setText(count);
            } else {
                break;
            }
        }

        scanner.close();
        
    }

5.課程設計感想

做爲組長，不單單是負責好本身的模塊，更重要的是團隊的協調合做。
通過此次課設我對我本身的能力有了深入的認識，各種代碼的應用還不熟練，要能在未來繼續認真的學習代碼，提升自身水平。
