用java实现扫雷游戏英雄榜的代码实现

以下是一个简单的Java扫雷游戏英雄榜的代码实现，其中使用了文件读写功能来保存玩家得分和排行榜信息：

Player.java:

public class Player {
    private String name;
    private int score;
    private String date;

    public Player(String name, int score, String date) {
        this.name = name;
        this.score = score;
        this.date = date;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getScore() {
        return score;
    }

    public void setScore(int score) {
        this.score = score;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }
}

HighScoreManager.java:

import java.io.*;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class HighScoreManager {
    private final String HIGHSCORE_FILE = "highscores.dat";
    private List<Player> scores;

    public HighScoreManager() {
        scores = new ArrayList<Player>();
    }

    public void addScore(Player player) {
        loadScoreFile();
        scores.add(player);
        updateScoreFile();
    }

    public List<Player> getTopScores() {
        loadScoreFile();
        sortScores();
        return scores;
    }

    private void sortScores() {
        Collections.sort(scores, new Comparator<Player>() {
            public int compare(Player p1, Player p2) {
                if (p1.getScore() < p2.getScore()) {
                    return 1;
                } else if (p1.getScore() > p2.getScore()) {
                    return -1;
                } else {
                    return 0;
                }
            }
        });
    }

    private void updateScoreFile() {
        try {
            FileOutputStream fos = new FileOutputStream(HIGHSCORE_FILE);
            ObjectOutputStream oos = new ObjectOutputStream(fos);
            oos.writeObject(scores);
            oos.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private void loadScoreFile() {
        File file = new File(HIGHSCORE_FILE);
        if (file.exists()) {
            try {
                FileInputStream fis = new FileInputStream(HIGHSCORE_FILE);
                ObjectInputStream ois = new ObjectInputStream(fis);
                scores = (List<Player>) ois.readObject();
                ois.close();
            } catch (IOException | ClassNotFoundException e) {
                e.printStackTrace();
            }
        }
    }
}

在游戏结束时，可以按以下方式调用HighScoreManager类的addScore方法：

HighScoreManager manager = new HighScoreManager();
Player player = new Player(name, score, date);
manager.addScore(player);

在游戏菜单中添加一个“查看排行榜”选项，可以按以下方式调用HighScoreManager类的getTopScores方法，并将返回的排行榜信息显示在界面上：

HighScoreManager manager = new HighScoreManager();
List<Player> topScores = manager.getTopScores();
// 显示排行榜信息
