java.io.IOException : mark/reset not supported

Question

该代码不起作用。我准备了一个类，因为可以找到它here ，但音乐不起作用。我该如何解决这个问题？

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);
} 

Answer 1

错误标记/重置不支持意味着您提供的输入流不支持设置标记并将流重置为该标记。要实现此目的，只需将 FileInputStream 包装在 BufferedInputStream 中(请参阅 http://docs.oracle.com/javase/7/docs/api/java/io/BufferedInputStream.html )

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