我的方法start()和not ()在括号中加了下划线，我不知道为什么？

Question

方法以红色下划线。我试图弄清楚为什么会发生这种情况，但我总是遇到无法解决的方法。我在主TextoToSpeechExample1类中有这些方法，并在gui类中调用这些方法。

class TextToSpeechExample1 {
    public static void main(String args[]) throws IOException, EngineException, AudioException, InterruptedException {

    static void start(){
            // code to be executed
            String fileName = "/Users/stevenshivayka/Documents/kjv.txt";
            Path path = Paths.get(fileName);
            byte[] bytes = Files.readAllBytes(path);
            List<String> allLines = Files.readAllLines(path, StandardCharsets.UTF_8);

//setting properties as Kevin Dictionary
            System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us" + ".cmu_us_kal.KevinVoiceDirectory");
//registering speech engine
            Central.registerEngineCentral("com.sun.speech.freetts" + ".jsapi.FreeTTSEngineCentral");
//create a Synthesizer that generates voice
            Synthesizer synthesizer = Central.createSynthesizer(new SynthesizerModeDesc(Locale.US));
//allocates a synthesizer
            synthesizer.allocate();
//resume a Synthesizer
            synthesizer.resume();
//speak the specified text until the QUEUE become empty
            synthesizer.speakPlainText(allLines.toString(), null);
            synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);
//deallocating the Synthesizer
            synthesizer.deallocate();
    }

    public static void pause(){
                Synthesizer synthesizer = Central.createSynthesizer(new SynthesizerModeDesc(Locale.US));
                synthesizer.allocate();
                synthesizer.resume();
                synthesizer.deallocate();
                synthesizer.pause();
        }
    }
}
    class gui {
        public static void main(String args[]) {
            JFrame frame = new JFrame("Babbel Audio Application");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setSize(400, 400);
            frame.setLayout(new FlowLayout());

            JButton button = new JButton("Start Audio");
            frame.add(button); // Adds Button to content pane of frame
            frame.setVisible(true);

            JButton button2 = new JButton("Pause Audio");
            frame.add(button2);
            frame.setVisible(true);

            button.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent e) {
                    //your actions
                    TextToSpeechExample1.start();

                }

            });

            button2.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent e) {
                    //your actions
                    pause();
                }
            });
        }
    }

`

我希望调用这些方法。如果你能回顾一下，看看我做错了什么，我会非常感激的。这是我自己正在做的一个项目。

这对StackOverflow来说不是个好问题，但无论如何.

据我所见，您在主方法中实现了两种方法-- start和pause -但是您需要在它之外实现它们。

试试这个：

class TextToSpeechExample1 {
    public static void main(String args[]) throws IOException, EngineException, AudioException, InterruptedException {}

    static void start(){
            // code to be executed
            String fileName = "/Users/stevenshivayka/Documents/kjv.txt";
            Path path = Paths.get(fileName);
            byte[] bytes = Files.readAllBytes(path);
            List<String> allLines = Files.readAllLines(path, StandardCharsets.UTF_8);

//setting properties as Kevin Dictionary
            System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us" + ".cmu_us_kal.KevinVoiceDirectory");
//registering speech engine
            Central.registerEngineCentral("com.sun.speech.freetts" + ".jsapi.FreeTTSEngineCentral");
//create a Synthesizer that generates voice
            Synthesizer synthesizer = Central.createSynthesizer(new SynthesizerModeDesc(Locale.US));
//allocates a synthesizer
            synthesizer.allocate();
//resume a Synthesizer
            synthesizer.resume();
//speak the specified text until the QUEUE become empty
            synthesizer.speakPlainText(allLines.toString(), null);
            synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);
//deallocating the Synthesizer
            synthesizer.deallocate();
    }

    public static void pause(){
                Synthesizer synthesizer = Central.createSynthesizer(new SynthesizerModeDesc(Locale.US));
                synthesizer.allocate();
                synthesizer.resume();
                synthesizer.deallocate();
                synthesizer.pause();
        }
    }

    class gui {
        public static void main(String args[]) {
            JFrame frame = new JFrame("Babbel Audio Application");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setSize(400, 400);
            frame.setLayout(new FlowLayout());

            JButton button = new JButton("Start Audio");
            frame.add(button); // Adds Button to content pane of frame
            frame.setVisible(true);

            JButton button2 = new JButton("Pause Audio");
            frame.add(button2);
            frame.setVisible(true);

            button.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent e) {
                    //your actions
                    TextToSpeechExample1.start();

                }

            });

            button2.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent e) {
                    //your actions
                    TextToSpeechExample1.pause();
                }
            });
        }
    }

Answer 2

快速查看您的代码，有几件事情会跳出：

1. 您正试图在public static void main(..)函数中声明一个新的函数static void start()。这在java是不允许的。您应该在类本身内声明函数：

class TextToSpeechExample1 {
   static void start() { ...your code here... }
   public static void pause() { ... your code here ... }
   public static void main (String args[]) { ... your code here ...}
}

您可能还应该了解Java中访问修饰符/说明符的基础知识。例如，您将无法从另一个类调用private函数或在private类中声明的函数。

空白开始和暂停在您的TextoToSpeechExample1类的主空中，从主空中删除它们，它不会产生错误。
