Update Java 容器.md
这这这没有因果关系啊:实现了 RandomAccess 接口,因此支持随机访问。 而且应该是 快速随机访问。 Marker interface used by <tt>List</tt> implementations to indicate that * they support fast (generally constant time) random access. The primary * purpose of this interface is to allow generic algorithms to alter their * behavior to provide good performance when applied to either random or * sequential access lists.

实现了 RandomAccess 接口,因此支持随机访问。这是理所当然的,因为 ArrayList 是基于数组实现的。
