How to invoke two run methods in one java file

below is the code where i need to invoke 2 run methods for 2 different threads any way this can be done. please help on this.

public class QuestionList extends ListActivity implements Runnable {
                //This below thread will call the run method
        Thread thread = new Thread(Quest开发者_JS百科ionList.this);
            thread.start();

         //can i have one more thread which call run1() method any idea

}


public void run() {


}

You cannot have two run() methods of course, and I suggest not using the same for both Threads (with a of if() statement to determine which behaviour to apply).

Instead you should create two distinct classes (why not inner classes) to implement these distinct behaviours. Something like:

public class QuestionList extends ListActivity {
    class BehaviourA implements Runnable {
        public void run() {
        }
    }

    class BehaviourB implements Runnable {
        public void run() {
        }
    }

    private void somewhereElseInTheCode() {
        BehaviourA anInstanceOfBehaviourA = new BehaviourA();
        Thread threadA = new Thread(anInstanceOfBehaviourA);
        threadA.start();

        BehaviourB anInstanceOfBehaviourB = new BehaviourB();
        Thread threadB = new Thread(anInstanceOfBehaviourB);
        threadB.start();
    }
}    

The good thing with inner classes is that they can access to the members of QuestionList, and this seems to be what you are willing to do.

    public class QuestionList extends ListActivity {
                    //This below thread will call the run method
            Thread1 thread1 = new Thread(this);
            thread1.start();

            Thread2 thread2 = new Thread(this);
            thread2.start();


    }

    class Thread1 implements Runnable
    {
       public void run() {


       } 
    }

   class Thread2 implements Runnable
   {
       public void run() {


       } 
   }
