Question

Toolkit toolkit = Toolkit.getDefaultToolkit();
    Clipboard clipboard = toolkit.getSystemClipboard();
    String result;
    try {
        result = (String) clipboard.getData(DataFlavor.stringFlavor);
        console.appendText("\nString being registerd to account: " + result);

        Jedis client = new Jedis("placeholder");
        client.rpush(userName, result);
        client.disconnect();
        client.close();

当我从按钮运行代码时，我收到一条错误消息，指出结果是错误的数据类型。是否与我从剪贴板中提取文本的方式有关，是否有其他方法可以执行此操作，因此不会抛出此错误？
