第一次在这里发帖。这是我的问题：我无法保存或加载配置文件。我正在尝试根据我的代码中指定的玩家数量来保存玩家名称。有谁知道出了什么问题以及如何解决？配置文件：
public void savePlayerConfiguration(String key, int value) {
String path = "config.xml";
try {
File file = new File(path);
boolean exists = file.exists();
if (!exists) {
file.createNewFile();
}
OutputStream write = new FileOutputStream(path);
properties.setProperty(key, Integer.toString(value));
properties.storeToXML(write, key);
} catch (Exception e) {
}
}
public void loadPlayerConfiguration(String path) {
try {
InputStream read = new FileInputStream(path);
properties.loadFromXML(read);
String player1 = properties.getProperty("1");
String player2 = properties.getProperty("2");
String player3 = properties.getProperty("3");
String player4 = properties.getProperty("4");
String player5 = properties.getProperty("5");
String player6 = properties.getProperty("6");
read.close();
} catch (FileNotFoundException e) {
savePlayerConfiguration("1", 1);
savePlayerConfiguration("2", 2);
savePlayerConfiguration("3", 3);
savePlayerConfiguration("4", 4);
savePlayerConfiguration("5", 5);
savePlayerConfiguration("6", 6);
loadConfiguration(path);
} catch (IOException e) {
}
}
