                }             }         }     }     return null; } }

and used work fine, now, when reaches 27%, gives error complaining how value must between 0 , 100, thing is, used work, , suddenly, doesn't. why?

the problem experiencing piece of code:

int percent = (totaldataread * 100) / filesize; download.status.settext(totaldataread / 1024 + "kb/" + filesize / 1024 + "kb"); setprogress(percent);

your value percent must outside range 0...100 exception message coming setprogress method: http://docs.oracle.com/javase/7/docs/api/javax/swing/swingworker.html#setprogress(int)

note:

illegalargumentexception - value not 0 100
