Help with sort algorithm

[zoe]

Hello, I need to re-write the Sorts class for arrays so that it sorts in descending order, example: high to low.
The best I can do is: if i put in 5 numbers, 1-5, and it sorts, it shows up as 1,4,5,2,3.
This Sorts class came from the book we use, and is the version that our teacher wants us to use.
In reference to the stickied topic, i have spent the better part of a week working on this, and the best i get is 1,4,5,2,3. I don't think anybody else in my class has finished this one either.

Code:

public class Sorts
{
   //-----------------------------------------------------------------
   //  Sorts the specified array of integers using the selection
   //  sort algorithm.
   //-----------------------------------------------------------------
   public static void selectionSort (int[] numbers)
   {
      int min, temp;

      for (int index = 0; index < numbers.length-1; index++)
      {
         min = index;
         for (int scan = index+1; scan < numbers.length; scan++)
            if (numbers[scan] < numbers[min])
               min = scan;

         // Swap the values
         temp = numbers[min];
         numbers[min] = numbers[index];
         numbers[index] = temp;
      }
   }

   //-----------------------------------------------------------------
   //  Sorts the specified array of integers using the insertion
   //  sort algorithm.
   //-----------------------------------------------------------------
   public static void insertionSort (int[] numbers)
   {
      for (int index = 1; index < numbers.length; index++)
      {
         int key = numbers[index];
         int position = index;

         // shift larger values to the right
         while (position > 0 && numbers[position-1] > key)
         {
            numbers[position] = numbers[position-1];
            position--;
         }
            
         numbers[position] = key;
      }
   }

Thanks

Here you go

Code:

   
   public static void selectionSort (int[] numbers)
   {
      int max, temp;

      for (int index = 0; index < numbers.length-1; index++)
      {
         max = index;
         for (int scan = index+1; scan < numbers.length; scan++)
            if (numbers[scan] > numbers[max])
               max = scan;

         // Swap the values
         temp = numbers[max];
         numbers[max] = numbers[index];
         numbers[index] = temp;
      }
    }

   //-----------------------------------------------------------------
   //  Sorts the specified array of integers using the insertion
   //  sort algorithm.
   //-----------------------------------------------------------------
   public static void insertionSort (int[] numbers)
   {
      for (int index = 1; index < numbers.length; index++)
      {
         int key = numbers[index];
         int position = index;

         // shift larger values to the left
         while (position > 0 && numbers[position-1] < key)
         {
            numbers[position] = numbers[position-1];
            position--;
         }
            
         numbers[position] = key;
      }
      
   }

Greetings.
