[RESOLVED]My program cannot work for float array

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,1.0f,15.0f}.
Here's my code:

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)));
                }
        }
}

I have found a solution to this problem, here is the code:

Code:

---

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));
  }
 }
}
