資源簡介
完成一個變形版的紙牌21點游戲。該游戲來源于21點游戲，實現人機對戰。游戲說明如下：
（1）該游戲需要兩副牌，沒有Joker，共104張。每張“紙牌”應具有花色與數字兩個屬性。
（2）游戲在機器與人類玩家之間進行。游戲一開始應先洗牌（將104張牌打亂）。
（3）機器永遠是莊家，所以永遠先給機器發牌，機器的牌不可見，只能看到機器要了幾張牌。機器停止要牌后，再給人類玩家發牌。
（4）游戲勝利與失敗的條件與普通21相同；除此以外，一方在當前牌沒有爆掉的前提下，如果下一張牌使得手中有兩張完全一樣的牌（同數字、同花色）則立刻勝利。
（5）游戲結束時機器的牌要全部顯示，并提示誰勝利了。
程序設計要求如下：
（1）程序中應至少有Card類和CardGame類。
（2）Card類需要重寫Object類的equals(Object o) 函數，用于比較兩張牌是否完全一樣；重寫toString函數，用于輸出牌時直接顯示牌的花色與數字。
（3）CardGame類應具有shuffle（洗牌）、deal（發牌）、win（勝利判別）等函數。
（4）選擇適當的java集合類來實現“發牌牌堆”和“手牌”（不允許都使用數組）。。
