Thread with same instance as lock Query

[Mohit G Gupta]

  class A implements Runnable{


     public synchronized void run(){
 System.out.println("jusbeforesleep");
           System.out.println(Thread.currentThread().getName());

          System.out.println(Thread.currentThread().getName());

     }

}


public class Multi{

     public static void main(String arguments[]){

          A b=new A();
          Thread rba=new Thread(b);
          Thread rbb=new Thread(b);
          rba.start();
            System.out.println(Thread.currentThread().getName());
          
          rbb.start();
     }

}


  

Is the following output possible ?
i think it is possible.
both threads lock on same instance,so they would block each other
any one either main or thread-0 thread-1 can run first
but i think jvm can stop thread 0 in between and run main and then switch back to thread-0

jusbeforesleep
Thread-0
main
Thread-0
jusbeforesleep
Thread-1
Thread-1
