您可以将任何对象存储为.dat文件：
public class MyGame implements Serializable { private static void saveGame(ObjectType YourObject, String filePath) throws IOException { ObjectOutputStream outputStream = null; try { outputStream = new ObjectOutputStream(new FileOutputStream(filePath)); outputStream.writeObject(YourObject); } catch(FileNotFoundException ex) { ex.printStackTrace(); } catch(IOException ex) { ex.printStackTrace(); } finally { try { if(outputStream != null) { outputStream.flush(); outputStream.close(); } } catch(IOException ex) { ex.printStackTrace(); } } } public static ObjectType loadGame(String filePath) throws IOException { try { FileInputStream fileIn = new FileInputStream(filePath); ObjectInputStream in = new ObjectInputStream(fileIn); return (ObjectType) in.readObject(); } catch(FileNotFoundException ex) { ex.printStackTrace(); } catch(IOException ex) { ex.printStackTrace(); } } }
