有界阻塞队列LinkedBlockingQueue

1. 创建

LinkedBlockingQueue 可以通过构造方法，创建一个指定容量的有界队列，如果不指定，默认长度是Integer.MAX_VALUE

/**
     * Creates a {@code LinkedBlockingQueue} with the given (fixed) capacity.
     *
     * @param capacity the capacity of this queue
     * @throws IllegalArgumentException if {@code capacity} is not greater
     *         than zero
     */
    public LinkedBlockingQueue(int capacity) {
        if (capacity <= 0) throw new IllegalArgumentException();
        this.capacity = capacity;
        last = head = new Node<E>(null);
    }
