Wie führe ich recorder.java mit fxml JavaFX aus?

Question

Ich möchte Stimme mit UI fxml aufzeichnen. Aber ich weiß nicht, wie man diese Java-Datei auf dem von mir erstellten UI-fxml ausführt.

JavaRecorder.java

package application; 

import java.io.File; 
import java.io.IOException; 

import javax.sound.sampled.AudioFileFormat; 
import javax.sound.sampled.AudioFormat; 
import javax.sound.sampled.AudioInputStream; 
import javax.sound.sampled.AudioSystem; 
import javax.sound.sampled.DataLine; 
import javax.sound.sampled.LineUnavailableException; 
import javax.sound.sampled.TargetDataLine; 

public class JavaRecorder { 

    static final long RECORD_TIME = 30000; // 0.5 minute 

     // path of the wav file 
     File wavFile = new File("C:/Users/Asus/Music/RecordAudio.wav"); 

     // format of audio file 
     AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE; 

     // the line from which audio data is captured 
     TargetDataLine line; 

     /** 
     * Defines an audio format 
     */ 
     AudioFormat getAudioFormat() { 
      float sampleRate = 16000; 
      int sampleSizeInBits = 8; 
      int channels = 2; 
      boolean signed = true; 
      boolean bigEndian = true; 
      AudioFormat format = new AudioFormat(sampleRate, sampleSizeInBits, 
               channels, signed, bigEndian); 
      return format; 
     } 

     /** 
     * Captures the sound and record into a WAV file 
     */ 
     void start() { 
      try { 
       AudioFormat format = getAudioFormat(); 
       DataLine.Info info = new DataLine.Info(TargetDataLine.class, format); 

       // checks if system supports the data line 
       if (!AudioSystem.isLineSupported(info)) { 
        System.out.println("Line not supported"); 
        System.exit(0); 
       } 
       line = (TargetDataLine) AudioSystem.getLine(info); 
       line.open(format); 
       line.start(); // start capturing 

       System.out.println("Start capturing..."); 

       AudioInputStream ais = new AudioInputStream(line); 

       System.out.println("Start recording..."); 

       // start recording 
       AudioSystem.write(ais, fileType, wavFile); 

      } catch (LineUnavailableException ex) { 
       ex.printStackTrace(); 
      } catch (IOException ioe) { 
       ioe.printStackTrace(); 
      } 
     } 

     /** 
     * Closes the target data line to finish capturing and recording 
     */ 
     void finish() { 
      line.stop(); 
      line.close(); 
      System.out.println("Finished"); 
     } 

     /** 
     * Entry to run the program 
     */ 
     public static void main(String[] args) { 
      final JavaRecorder recorder = new JavaRecorder(); 

      // creates a new thread that waits for a specified 
      // of time before stopping 
      Thread stopper = new Thread(new Runnable() { 
       public void run() { 
        try { 
         Thread.sleep(RECORD_TIME); 
        } catch (InterruptedException ex) { 
         ex.printStackTrace(); 
        } 
        recorder.finish(); 
       } 
      }); 

      stopper.start(); 

      // start recording 
      recorder.start(); 
     } 
    } 

unten Codierung für UI fxml ..

Main.java

package application; 

import javafx.application.Application; 
import javafx.stage.Stage; 
import javafx.scene.Scene; 
import javafx.scene.layout.AnchorPane; 
import javafx.fxml.FXMLLoader; 


public class Main extends Application { 
    @Override 
    public void start(Stage primaryStage) { 
     try { 
      AnchorPane root = (AnchorPane)FXMLLoader.load(getClass().getResource("First.fxml")); 
      Scene scene = new Scene(root,717,700); 
      scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm()); 
      primaryStage.setScene(scene); 
      primaryStage.show(); 
     } catch(Exception e) { 
      e.printStackTrace(); 
     } 
    } 

    public static void main(String[] args) { 
     launch(args); 
    } 

}

Answer 1

Vielleicht möchten Sie die "First.fxml" zu "/First.fxml",

AnchorPane root = (AnchorPane)FXMLLoader.load(getClass().getResource("/First.fxml")); 

ändern auszuprobieren und dann dielaufen 10 Methode aus der Main Klasse.
