序列换&反序列化

//所有要序列化的类都必须实现Serializable接口

		FileOutputStream fos = new FileOutputStream(file);
		BufferedOutputStream bos = new BufferedOutputStream(fos);
		ObjectOutputStream oos = new ObjectOutputStream(bos);
		oos.writeObject(d);

//关闭必须由内而外！
		oos.close();
		bos.close();
		fos.close();
		System.out.println("ok");

		Dog d = (Dog)ois.readObject();
		System.out.println(d.getName());
		ois.close(); 
		bis.close();
		fis.close();
