此代码不起作用。我已经准备好了一堂课,因为它可以找到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);
}

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(参见http://docs.oracle.com/javase/7/docs/api/java/io/BufferedInputStream.html)
InputStream arquivo=null;
...
arquivo=new BufferedInputStream(new FileInputStream(...));
