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,1.0f,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.
