关于Arrays.asList()方法是生成的一个内部的java.util.Arrays.ArrayList,不是java.util.ArrayList,这个要注意,它不具备添加和删除的方法。 为什么不是线程安全的,具体来说是哪里不安全?(源码层面,没答上来) 在高并发添加数据下,ArrayList会暴露三个问题; 部分值为null(我们并没有add null进去) 索引越界异常 size...
3)api中接下来讲的一大堆,就是说明linkedList是一个非线程安全的(异步),其中在操作Interator时,如果改变列表结构(add\delete等),会发生fail-fast。 通过API再次总结一下LinkedList的特性: 1)异步,也就是非线程安全 2)双向链表。由于实现了list和Deque接口,能够当作队列来使用。
