No it's not possible because you can not extend more than one class but you can implement more than one interface which is not of any use here.

Java does not support multiple inheritance, more than one class can not be extended but there is solution , but in your case i think you can use like this:

  class MapActivity extends Service{
   ...
  }

 class mainactivity extends ListActivity{

  MapActivity mapActivity= new MapActivity();
 }

no its not possible because in core java a class can only inherit one class . In c++ its possible to inherit more than one class. So thats why its not possible

you can't . java doesn't let that type of polymorphism . You must use implements for interfaces .
