Question

我正在将Spinx语音识别作为一个线程运行，并希望将结果传递给一个bot方法，该方法镜像Main中的相同方法来传递文本。然而，继续运行NullPointerExpection并且无法推断或克服它。为什么它在Main中有效，但在Reply类中无效。

Main中的文本发送按钮是：

private void onSend(java.awt.event.ActionEvent evt) {                        
        // display users message
        txtHistory.setText(txtHistory.getText() + "\nYou: " + txtMessage.getText() + "\n");

        //send the input to the bot and get bot response
        String response = bot.send(txtMessage.getText());

        //if the response is not empty show it
        if (response.length() > 0) {
        addBotText(response);
        }   
        //display new state message to continue
        addBotText(bot.getMessage());    

       //clear the input message box
       txtMessage.setText("");

  }

在Runnable（Threaded）Spinx Reply类中，我有一个方法来获取语音输入，然后将其显示为字符串：

    private void start_recognition(Result result) {

            if (result != null) {
                String resultText = result.getBestFinalResultNoFiller();
                //send the message to the bot
                String response = bot.send(resultText);
                System.out.println("You said: " + resultText + '\n');
            } else {
                System.out.println("I can't hear what you said.\n");
        }
   }

（使用私人Bot机器人;在Main和Reply中都有评论）当我评论String response = bot.send（resultText）; out all is well，但是尝试调用bot.send方法会创建一个nullPointerException。我意识到我正在做一些令人难以置信的愚蠢但却无法理解的事情。 Bot方法如下。非常感谢任何帮助。

在Bot类中发送方法：

   public String send(String message) {

    String response = "";
    State state = parser.getState(level);

    // end of the tree
    if (state.getKeywords().isEmpty()) {
        this.level = "1";
    }

    // match the keyword with given message
    Keyword match = parse(message, state.getKeywords());

    // if no keyword is matched, display one of the invalid answers
    if (match == null) {
        response = parser.getInvalidAnswer();
    } else {

        // if match classname is provided, check to get the dynamic response
        if (match.className.length() > 0) {

            // check for Weather dynamic response
            if (match.className.equals("Weather")) {
                Weather weather = new Weather();
                response = weather.getResponse(match.arg);
                this.level = "1";
            }
            // check for News dynamic response
            if (match.className.equals("News")) {
                News news = new News();
                response = news.getResponse(match.arg);
                this.level = "1";
            }
        } else {

            // get the new state and return the new message
            if (response.length() == 0) {

                this.level = match.target;
                state = parser.getState(level);

                // if it is end of the tree
                if (state.getKeywords().isEmpty()) {
                    response = this.getMessage();
                    this.level = "1";

                }
            }
        }
    }
    return response;
}

条件机器人的所有代码都归功于Majid Khosravi

重用一种方法来传递文本字符串和语音输入，但是获取NullExceptionPointer并且无法弄明白
