在java中搜索对象列表的更好方法

Question

I have an object for servers with hostname and some sort of other fields. I'm searching my Database and get a List<Server> . So now I have another list of orders, which have besides some other fields a field for hostname.

At the moment I'm either iterating through list 1, get the hostname and then iterate trough list 2 and try to find the equal hostname, or I'm not making a list of servers but a HashMap<Hostname, Server> and look with contains if there is my hostname.

I want to know if there is a more elegant way to do this?
