Override method but parameter is arg0

i use eclipse auto Override a method: ``` @Override public void draw(Canvas arg0, MapView arg1, boolean arg2) { // TODO Auto-generated method stub super.draw(arg0, arg1, arg2); } ``` you see ,the parameter is arg0,arg1,arg2,it is hard to read.i think if my eclipse is have mistake, because i think it should give me : ``` draw(Canvas canvas, MapView mapview, boolean flag) ``` so my question why my eclipse give me arg0 and so on,how to solve it?
