In this article, we are going to learn about Vector class of Java. Here, we will explain about it with the help of example.

好的,下面是这个的完整解释 Fail-Fast 机制 我们知道 java.util.ArrayList 不是线程安全的,ArrayList,那么将抛出ConcurrentModificationException,这就是所谓fail-fast策略。 这一策略在源码中的实现是通过 modCount 域,modCount 顾名思义就是修改次数,对ArrayList 内容的修改都将增加这个值,那么在迭代器初始化过程中会...

Vector 是一个相当古老的 Java 容器类,始于 JDK 1.0,并在 JDK 1.2 时代对其进行修改,使其实现了 List 和 Collection 。从作用上来看,Vector 和 ArrayList 很相似,都是内部维护了一个可以动态变换长度的数组。 但是他们的扩容机制却不相同。对于 Vector 的源码大部分都和 ArrayList 差不多,这里简单看下 Vector ...
