Collections.shuffle();

simple demo (using numbers 0 to 51 instead of 'Ace of Hearts' etc)

import java.util.*;
class Testing
{
  public Testing()
  {
    Deck deck = new Deck();
    deck.printDeck();
    System.out.println("===");
    deck.shuffleDeck();
    deck.printDeck();
  }
  public static void main(String[] args){new Testing();}
}
class Deck
{
  List cards = new ArrayList();
  public Deck()
  {
    for(int x = 0; x < 52; x++)
    {
      cards.add(new Card(x));
    }
  }
  public void printDeck()
  {
    for(int x = 0, y = cards.size(); x < y; x++)
    {
      System.out.println(((Card)cards.get(x)).face);
    }
  }
  public void shuffleDeck()
  {
    Collections.shuffle(cards);//<-----------------------
  }
}
class Card
{
  int face;
  public Card(int f)
  {
    face = f;
  }
}
