How to create a sorted set from the contents of an array

Hello people,

I need to write a public class method that has an array of integers as its argument and returns a sorted
set containing all of the elements of that array.
Im really stuck on this but my best attempt is as follows but this returns errors already when i Try to compile.

Code :

---

 
  public SortedSet arrayToSortedSet(Integer[] anArray)
  {
     Set<Integer>aSet =new TreeSet<Integer>();
     aSet.add(anArray);
     return aSet;
   }

---

Sorry this is such a noob question but I just cant work out how to do it.

Well, this works, although there may be a more elegant solution.

Array is not a Collection, so you cannot use TreeSet's "addAll" or constructor to include elements. Sorry... you'll have to loop the good old-fashioned way, adding one element at a time.

Next, aSet must be declared to be of type SortedSet or TreeSet. Set won't work because you need to return a SortedSet
and SortedSet is a subclass of Set. So yeah, the following code should work...

Code :

---

       public SortedSet arrayToSortedSet(Integer[] anArray)
      {
         SortedSet<Integer>aSet = new TreeSet<Integer>();
 
         for(int i = 0; i < anArray.length; i++)
            aSet.add(anArray[i]);
 
         return aSet;
      }

---

A perhaps more elegant solution is to find some type of collection that will allow you to convert arrays, and then use that collection with the treeset. Personally, I think this is alright.
