Can't shuffle

[anjkris07]

I've been studying java for a week now. I have a project that needed to display a deck of cards and shuffle them alternately (like cutting the deck then insert each card). Then deal it, much like the war game of cards. I'm just still on the shuffle stage but the the deck remains the same even after shuffling. I think my codes got problem with the swapping part. I try to think of another way to shuffle(not randomly) but nothing came up. So please HELP

import java.io.*;
import java.util.*;
 
 public class Deck{
 
        Vector deck; // create a 52-card deck
         final String[] suit = {"D", "H", "S", "C"};
         final String[] rank = {"A","K", "Q", "J", "T", "9", "8", "7", "6", "5", "4", "3", "2"};
 
         public Deck(){
 
        // creating a list
         List<String> list = new ArrayList<String>();
            for (int i = 0; i < suit.length; i++)
            {
          for (int j = 0; j < rank.length; j++)
            list.add(rank[j] + suit[i]);
            }
            // convert the array to vector
          deck = new Vector(list);
 
            // access elements
            System.out.println("Initial Deck:"); 
            Enumeration deck1 = deck.elements();    
            while (deck1.hasMoreElements())
           {  
                System.out.println(deck1.nextElement().toString());             
            }
 
    }
 
    public void shuffle()throws IOException{
 
 
        BufferedReader br = new BufferedReader(new InputStreamReader (System.in));
        System.out.println ("Enter the desired number for shuffle: ");
        String temp = br.readLine();
        int count = Integer.parseInt(temp);
 
            for (int b=0; b<=count; b++)
                {
                for (int i=1;i<(deck.size())/2;i+=2)
                    {            
                      for (int j=26;j<(deck.size())/2;j+=2)
                     {
                         Collections.swap(deck, i, j);}
                     } 
                }System.out.println("Shuffled Deck:\n" + deck);    
    }
 
 
 
 
 
        public static void main (String[] args) throws IOException{
                Deck cardeck = new Deck();
                cardeck.shuffle();    
    }
}

The for loops are to blame:
for (int j=26;j<(deck.size())/2;j+=2)

if deck.size() = 26, then j >= 26 from the start -> the for loop never runs.
