public class Deal{
public static void main(String[] args)
{
int numHands=Integer.parseInt(args[0]);
int cardsPerHand=Integer.parseInt(args[1]);String[] suit=new String[]{"spades","hearts","diamonds","clubs"};
String[] rank=new String[]{"ace","2","3","4","5","6","7","8","9","10","jack","queen","king"};List deck=new ArrayList();
for(int i=0;i<suit.length;i++)
 for (int j=0;j<rank.length;j++)
deck.add(rank[j]+"of"+suit[i]);Collections.shuffle(deck);  for(int i=0;i<numHands;i++)
 System.out.println(dealHand(deck,cardsPerHand));}
public static List dealHand(List deck,int n){
int deckSize=deck.size();
List handView=deck.subList(deckSize-n,deckSize);
List hand =new ArrayList(handView);
handView.clear();
return hand;}}
各位高手到底是哪里错了?
