如何在Java中解决关闭游戏后高分重置为0的问题

Question

1st time: My high score is 50 and it saves my score to file
2nd time: I close the game and run it back my score is 30. It still saves it to high score file
This is because the high score every time it runs is 0.

private String highScore = "Nobody:0"; //I think this is the problem because highscore =0 at start
public void CheckHighScore() {
        if (score > Integer.parseInt((highScore.split(":")[1]))) {

            String name = JOptionPane.showInputDialog("You set a new highScore. What 's your name?");
            highScore = name + ":" + score;

            File scoreFile = new File("highscore.dat");
            if (!scoreFile.exists()) {
                try {
                    scoreFile.createNewFile();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            FileWriter writeFile = null;
            BufferedWriter writer = null;
            try {
                writeFile = new FileWriter(scoreFile,true);
                writer = new BufferedWriter(writeFile);
                writer.write(this.highScore);
                writer.newLine();
            }
            catch (Exception e) {

            }
            finally {
                try {
                    if (writer != null)
                        writer.close();
                }
                catch (Exception e) {}

            }
        }
    }

你能回答一个问题吗？

i.）当游戏加载时，你想让你的最后一个高分列表可用吗？如果是，那么你不从文件中读取任何东西，而是简单地向它写入。你可以简单地从列表中获取最高的分数。

->如果第一部分为true，则yes,字符串highScore=“nobody:0”是错误的，因为您每次都将该值初始化为零，相反，应该从存储数据的文件中读取该值。
