綜合練習——洗牌發牌Easy版

Card程式碼，裡面是卡牌的屬性，重寫了equals方法，並且實現了Comparable介面。這裡因為要求只是比較大小，所以我在屬性裡多新增了一條，用多加的這條屬性來進行比較，由數字10,20,30,40,50,60,70,80,90,91,92,93,94還有顏色用A-D表示，組合而成的一個字串，這樣去排序看大小的話會非常方便。
因為一般的時候2是最大的牌。2用94，A93，K92，Q91，J90，10用80……3用10。後面跟著如果數字相同則比較花色，如黑紅梅方，用DCBA來表示，比如說當都是2時，前兩位都是94，方片2是94A，黑桃2就是94D。這樣升序會排在對方後面。直接排序然後取最大的值就可以了。再用最大的值和當時的手牌去比較，相同的那位玩家獲勝。
