为什么输出的扑克总是红桃A

Question

//创建方法，用来创建扑克牌 public void creatPoker() {     System.out.println("--------------创建扑克牌----------------");     System.out.println("扑克牌创建成功！");     //使用switch语句，用来遍历花色和数字     for (int i = 0; i < 4; i++) {         switch (i) {             case 0:                 cardType = "方片";                 break;             case 1:                 cardType = "梅花";                 break;             case 2:                 cardType = "黑桃";                 break;             case 3:                 cardType = "红桃";                 break;         }         for (int j = 2; j <= 14; j++) {             if (j > 10) {                 switch (j) {                     case 11:                         cardNumber = "J";                         break;                     case 12:                         cardNumber = "Q";                         break;                     case 13:                         cardNumber = "K";                         break;                     case 14:                         cardNumber = "A";                         break;                 }             } else {                 cardNumber = j + "";             }             System.out.println("已添加扑克：" + cardType + cardNumber);             pokerList.add(new Poker(cardType, cardNumber));         }     }     for (Poker temp : pokerList) {         System.out.println("扑克牌为：" + temp.cardType + temp.cardNumber);     } }
