public void pokerSetUp(){

Poker pokerCard = new Poker();

List pokerList = new ArrayList();

String[] pokerstr1 = {"黑桃","红桃","梅花","方片"};

String[] pokerstr2 = {"2","3","4","5","6","7","8","9","10","J","Q","k"};

System.out.println("----------创建扑克牌----------");

for(int i=0;i < 4;i++){

for(int j=0;j < 12;j++){

pokerCard.pokercard1 = pokerstr1[i];

// System.out.println(pokerstr1[i]);

// System.out.println(pokerCard.pokercard1);

pokerCard.pokercard2 = pokerstr2[j];

// System.out.println(pokerstr2[j]);

// System.out.println(pokerCard.pokercard2);

pokerList.add(pokerCard);

}

}

System.out.println("----------扑克牌创建成功----------");

System.out.println("为：");

/**
