TestClass.java:

import java.util.List;
import java.util.Map;

public class TestClass
{
   List myList = null;
   Map myMap = null;

   public void function(Integer one, Integer two)
   {
      int index = 3;
      for (; index > 0; index--)
      {
         Integer key = (Integer) myList.get( index - 1);
         ((Double)myMap.get( key)).doubleValue();
      }
}
