I have a vector (LimitSet) of "Limit" objects, a limit consisting of an integer (pos) and a double (speed). How would I (if I even can) use Collections.sort to order the contents of the LimitSet by "pos"?

Use the version of sort() that takes a java.util.Comparator as an argument. Provide a Comparator implementation which compares two Limit objects by subtracting their "pos" members and returning the result.

You could either modify the definition of LimitSet to implement Comparable or create a Comparator to use to call Collections.sort
 
Don't get me started about those stupid light bulbs.
