Estoy tratando de descargar un archivo zip pero recibo una Excepción de transmisión cerrada. Cuando utilizo el uso de la función swing gui, obtengo este error, pero si uso la consola no hay problema. ¿Por qué obtengo esta excepción? ¿Cómo puedo arreglarlo?¿por qué obtengo java.io.IOException: Stream cerrado?
Este es mi código: trace
URLConnection conn = url.openConnection();
InputStream in = conn.getInputStream();
FileOutputStream out = new FileOutputStream(destination.getPath());
byte[] b = new byte[1024];
int count;
while ((count = in.read(b)) >= 0) {
out.write(b, 0, count);
}
out.flush();
out.close();
in.close();
OptionPane.showMessageDialog(null, "Download is finished");
} catch (HttpUnauthorizedException e) {
JOptionPane.showMessageDialog(null, "Proxy or Server Authentication Required");
} catch (IOException e) {
System.out.println(e.getMessage());
}
esto se apile
java.io.IOException: Stream closed.

seguimiento de pila por favor –
obtengo la excepción aquí: 'while ((count = in.read (b))> = 0) { out.write (b, 0, count); } ' – itro
