HELP!! My program cannot work for float array

[huiling25]

My program works alright for integer array, but not float array. How can I change the program so that I can get the original position of each element in the float array after sorting? Let's say my float array is {5.0f,10.0f,1.0 f,15.0f}.
Here's my code:

import java.util.*;

public class SortArrays
{
	public static void main(String args[])
	{
		Integer[] score = {5, 10, 0, 1, 15};

		ArrayList Values = new ArrayList();
		HashMap OriginalPos = new HashMap();

		for(int i=score.length-1;i>=0;i--)
		{
			OriginalPos.put(new Integer(score[i]), new Integer(i));
			Values.add(new Integer(score[i]));
		}
	
		Collections.sort(Values);

		for(int i=Values.size()-1;i>=0;i--)
		{
			int val = ((Integer)(Values.get(i))).intValue();
			System.out.print("" + val + "    ");
			System.out.println(OriginalPos.get(new Integer(val)));
		}
	}
}

Remember 1.5 has autoboxing and unboxing. Also make use of generic types

 import java.util.*; 
public class SortArrays {
 public static void main(String args[]) {
  Float[] score = {5.0f, 10.0f, 0.0f, 1.0f, 15.0f};
  ArrayList<Float> values = new ArrayList<Float>();
  HashMap<Float, Integer> originalPos = new HashMap<Float, Integer>();
  for(int i=score.length-1;i>=0;i--) {
   originalPos.put(score[i], i);
   values.add(score[i]);
  }
  Collections.sort(values);
  for(int i = values.size()-1; i >= 0; i--) {
   float val = values.get(i);//No need for typecasting
   System.out.print("" + val + "	");
   System.out.println(originalPos.get(val));
  }
 }
}

Thanks for the solution, it works now.

Anytime, huiling25. One day I shall ask what your user name means.
