java.io.IOException:不支持mark/reset

Question

此代码不起作用.我准备好上课,因为它可以在这里找到,但音乐不起作用.我怎样才能解决这个问题？

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

不支持错误标记/重置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.要实现这一点,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(...));
