Real random numbers? Any way to seed this?

[voidflux]

Hello everyone!!

I'm making a poker game, and I need a way to make the dealing randomized, Right now I have a [4][13] array of card objects, and my get function is the following:

I can't have the random numbers be anyting other than
0 to 3 for the columns and 0 to 12 for the rows, because anyhting else will be out of range.

  public void getCard(int howMany)
  {
    Random r = new Random();
    
    
    while(howMany != 0)
    {
      int col = r.nextInt(4);
      int row = r.nextInt(13);
      
      if (theDeck[col][row].inDeck) {
        theDeck[col][row].inDeck = false; //take the card out of the deck
        System.out.print(theDeck[col][row].faceType +
                         theDeck[col][row].cardValue + " ");
        --howMany;    
      }
      else
        continue;
    }
    System.out.println();
  }

Is there anyway to make this more random?


Thanks!

You can seed either by passing in a long value to the Random constructor or by calling setSeed(long seed).

Thanks, I ran my program about 10 times and it gives me random different random numbers each time, so i'm just not going to mess with the seed.
