Java：对象到byte []和byte []到对象转换器（对于东京内阁）

public static byte[] serialize(Object obj) throws IOException {    ByteArrayOutputStream out = new ByteArrayOutputStream();    ObjectOutputStream os = new ObjectOutputStream(out);    os.writeObject(obj);    return out.toByteArray();}public static Object deserialize(byte[] data) throws IOException, ClassNotFoundException {    ByteArrayInputStream in = new ByteArrayInputStream(data);    ObjectInputStream is = new ObjectInputStream(in);    return is.readObject();}
