pass-vy-value problem

[Pedro José Gil Villar]

        I've got a problem, probably an easy one, but i can't manage to solve it
:-(

        I try to fill an ArrayList and then print it, but since Java pass only
handles to object, he just keep the last value for every item in the
ArrayList. I've read something about clone, but i can't make it work.

        The source is:

import java.util.ArrayList;
import java.lang.Double;
import java.util.Random;
import java.lang.System;

public class myclass {
   public ArrayList al;
   public Double d;
   public Random alea;

   public myclass() {
      al = new ArrayList(10);
      alea = new Random();
   }

   public static void main (String[] args) {

      myclass c = new myclass();
      double real;
      int i;

      // Fill the ArrayList
      for (i = 0; i<10; i++) {
         c.d = new Double(c.alea.nextDouble());
         c.al.add(i,c.d);
         System.out.println("Start: " + ((Double) c.al.get(i)).toString());
      }

      // Print the data from the ArrayList
      for (i = 0; i<10; i++) {
         c.al.add(i,c.d);
         System.out.println("End: " + ((Double) c.al.get(i)).toString());
      }
   }
}

        And the results are (those are an example, because i use a Random
generator):

        Thanks in advance.
