java 深克隆clone对象或容器的另一种方法

public static <T> T deepCopy(T src) throws IOException, ClassNotFoundException{   
        ByteArrayOutputStream byteOut = new ByteArrayOutputStream();   
        ObjectOutputStream out = new ObjectOutputStream(byteOut);   
        out.writeObject(src);   
       
        ByteArrayInputStream byteIn = new ByteArrayInputStream(byteOut.toByteArray());   
        ObjectInputStream in =new ObjectInputStream(byteIn);   
        T dest = (T) in.readObject();   
        return dest;   
    }
