Java Forum / First Aid / August 2006Vector Sort
Hi All - What's the best way to sort a vector of Integers? Thanks, Chris > Hi All - > > What's the best way to sort a vector of Integers? > > Thanks, Chris Chris: The simplest way is to remove the elements from the Vector to an array. The using Arrays.sort(), sort them and put them back into the vector. You will need to write a Comparator to use with the sort. Well I just looked at TreeSet and that might actually be simpler. Just pass your Vector to the TreeSet constructor and they should be sorted when you retrieve them. I think I like this answer better.

Why not just apply Collections.sort to the vector, which does essentially the same thing with one call? Also, Integer is Comparable, so a Comparator is needed if, and only if, the sort is in some special order.

I think I like this answer better. Putting the items in the vector into a treeset may cause you to lose duplicate values. - Oliver Free MagazinesGet these publications absolutely FREE for up to 12 months.
