stack(栈) 栈(stack)是一种先进后出(Last In First Out,LIFO)的数据结构,类比于现实生活中的子弹上膛、泡泡圈。栈具有两个基本操作:入栈(push)和出栈(pop)。入栈表示将元素放入栈顶,而出栈表示从栈顶取出元素。 动图图解-入栈(push) 动图图解-出栈(pop) 在Java的工具包中其实帮我们封装好了一个类,java...
简单的来说:在java.util下的集合都是发生fail-fast,而在java.util.concurrent下的发生的都是fail-safe。 1)fail-fast 快速失败,例如在arrayList中使用迭代器遍历时,有另外的线程对arrayList的存储数组进行了改变,比如add、delete、等使之发生了结构上的改变, 所以Iterator就会快速报一个java.util.ConcurrentModification...
