一、样例章节1

1. 代码的规范

   /**
    * Extracts element at current take position, advances, and signals.
    * Call only when holding lock.
    */
   private E dequeue() {
       // assert lock.getHoldCount() == 1;
       // assert items[takeIndex] != null;
       final Object[] items = this.items;
       @SuppressWarnings("unchecked")
       E x = (E) items[takeIndex];
       items[takeIndex] = null;
       if (++takeIndex == items.length)
           takeIndex = 0;
           count--;
           if (itrs != null)
               itrs.elementDequeued();
           notFull.signal();
           return x;
       }
