Seeking LinkedList variant of fixed length, sort of
<p>I know that the title doesn't really say what I'm actually looking for, as its hard to explain in few words.</p>

<p>What I'm looking for is a Linked List variant for Java I can iterate over, but which has something of a fixed length in a way.</p>

<p>You see, I want to track a ground path of simulated satellite in Kerbal Space Program, with data I get from a Telemetry Plugin. But I only want to display the ground path over the last about two hours. Now the entire data would be written into the Linked List, but as time goes by the list grows longer and longer and eventually its so large that it takes longer to iterate over this list to get the data of the last two hours of the orbit then it takes for a new set of data to come in.</p>

<p>So the Linked List variant I'm looking for would be of a somewhat fixed length that deletes the last entry(entries) if the time between the eldest and the newest entry are over two hours mission time. So that I only have to iterate over a relatively low number of entries and not the entire dataset of the previous flight (which is saved to bump it to CSV).</p>

<p>I appreciate any help that may be rendered by the helpful people around here.</p>
