Im writing a program for a programming class, and need to test to see if an ArrayList is sorted.

There is a function that sorts the arrayList, but I have another function that is supposed to print the ArrayList into a text file if the ArrayList is sorted.

Is there a class in the java API that contains a fuction to test if the ArrayList is sorted?

i havent used java in a while but i Know theyre are interfaces that classes can implement ( Comparable or Comparator i think) to allow them to be sorted, ie being able to compare if obj1 is > obj2. if you are storing objects of classes that you have made then look into these interfaces to see how to design the required method for your case.

i dont think there is any generic 'sort' function because it depends completely on the data, and how it _can_ be sorted, what the first element would be, etc etc.

sorting methods arent overly complicated. in your add or insert method compare the new item to items that are already in the list. the ones that are in the list you know will already be sorted.

im kinda tired right now so dont know if im helping--hope it does help.

If there isn't a function for that in the standard library, it would be trivial to write one (one way is to compare each adjacent item to see if they are in proper order)
