java.io.IOException: mark/reset not supported

问题:

This code does not work. I took a class ready since it can be found here, but the music does not work. How can I fix this?

private void lblCliqueMouseClicked(java.awt.event.MouseEvent evt){                                           lblClique.setText("achou");      musica = new Som();      boolean repetir = false;       FileInputStream arquivo = null;      try {          arquivo = new FileInputStream("musica.mp3");      } catch (FileNotFoundException ex) {          Logger.getLogger(TelaProjeto.class.getName()).log(Level.SEVERE, null, ex);      }      musica.tocar(arquivo, repetir); }  

回答1:

The error mark/reset not supported means the input stream you provided does not support setting a mark and resetting the stream to that mark. To achieve this, just wrap your FileInputStream inside a BufferedInputStream (see http://docs.oracle.com/javase/7/docs/api/java/io/BufferedInputStream.html)

InputStream arquivo=null; ... arquivo=new BufferedInputStream(new FileInputStream(...));
