help With Java SelectionSort numbers to display ascending and descending Order.

This is the program _ i want to put this in descending order,

Pls help me as soon as possible....

// program to demonstrate the selection sort

class SelectionSort
{
	// method to display the contents of an array
	static void displayData(int[] data)	
  {
		for (int index=0; index != data.length; index++)
			System.out.println(data[index]+"\t");
	}
 
  static int positionOfLargest(int[] data, int limit)
  {
    // method to return the position of the largest item 
    // in the data with bounds 0..limit
 
  	int largest = data[0];
  	int indexOfLargest = 0;
 
  	for (int index=1; index <= limit; index++)
      {
  		if (data[index]> largest)	
            {
  			largest = data[index];
  			indexOfLargest = index;
  		}
  	}
  	return indexOfLargest;
  }
 
  public static void selectionSort(int[] data)
  {
    // method to sort the contents of an data into 
    // scending order
 
  	int temporary;
  	int position;
  	int size=data.length;
 
  	for (int index=size-1; index > 0; index--)
      {
  		position=positionOfLargest(data, index);
 
  		// swap numbers
  		if (index != position)
            {
  			temporary = data[index];
  			data[index] = data[position];
  			data[position] = temporary;
		}
  	}
  }
 
	public static void main(String[] args)	
     {
		int[] data = {18,7,15,8,13};
 
		System.out.println("numbers before being sorted\n");
		displayData(data);
 
		selectionSort(data);
 
		System.out.println("numbers after being sorted\n");
		displayData(data);
	}
}

Change the sort in descending Order?
