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;    }复制代码
