question

  1. i don't meaning of super.run() , super.handlemessage(msg) necessaary?
  2. where should code written? before super.run() or after them?

answer - 1

this unnecessary in code in question.

new thread(){     @override     public void run() {         super.run();     } }.start();  public class thread implements runnable {     ...     @override     public void run() {         if (target != null) {             target.run();         }     }     ... }

super.run call thread class. therefore, not necessary because there empty function.

answer - 2

please refer answer -1, don't have worry it.

however, if super.x implemented, have write code depends on function.
