Thread notification don't work

I can't find reason why ThreadA gets notification from ThreadB only when ThreadB completely finishes it's job. If I comment notify() ThreadA gets notification anyway.

Does ThreadB sends notification automatically when finishes it's job?

Why ThreadB does't notify ThreadA on time?

class ThreadA {
      public static void main(String [] args) {
         ThreadB b = new ThreadB();

         b.start();

         synchronized(b) 
         {

            try {
               System.out.println("Waiting for b to complete...");
               b.wait();
               System.out.println("waiting done");
               } catch (InterruptedException e) {}

           System.out.println("Total is: " + b.total);

        }
     }
  }





class ThreadB extends Thread {   
     int total=0; 
     public void run() {
        synchronized(this) 
        {


           for(int i=0;i<10;i++) 
           {
              System.out.println(Thread.currentThread().getName()+" "+ Integer.toString(i));
              total += i;
           }


           notify();
           System.out.println("notify done");

           for(int i=0;i<100;i++) 
           {
              System.out.println(Thread.currentThread().getName()+" "+ Integer.toString(i));
              total += i;
           }

        }
     }
  }

Output:

Waiting for b to complete...

Additional question - why Total is 235 in output?
