Randomness of shuffled cards

I have an Array List of cards containing 52 cards. I want to shuffle the deck.

This is what I have done.

1. Created a new Array List.
2. Generated random index between 0 to deck size.
3. Get card at random index and add to new list.
4. Remove card from deck
5. Repeat until deck is empty.

Here is my code:

String[] Number = {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};String[] Suits = {"Club","Diamonds","Hearts","Spades"};ArrayList<Card> deck = new ArrayList<Card>();// create a deck    for(int i=0;i<13;i++){        for(int j=0;j<4;j++){            Card card = new Card(Suits[j],Number[i]);            deck.add(card);        }        }// shuffle of deckArrayList<Card> new_deck = new ArrayList<Card>();    while(deck.size()!=0){           Random rand = new Random();        int  n = rand.nextInt(deck.size());        new_deck.add(deck.get(n));        deck.remove(n);    }// Displayfor(int i=0;i<52;i++){        System.out.println(new_deck.get(i).getSuit()+" : "+new_deck.get(i).getValue());    }

Finally, I get the shuffled deck from new ArrayList.

Is its randomness good enough or not?

What should I do to increase randomness?
