Java入门第三季 - 扑克牌游戏

分别创建了四个类：牌类(Card)、玩家类(Player)、方法类(Method)、入口类(Initial)。

Card.java

class Card implements Comparable<Card> {
    String point;
    String suit;
    Integer pointWeight;
    Integer suitWeight;

    Card(String point, String suit, int pointWeight, int suitWeight) {
        this.point = point;
        this.suit = suit;
        this.pointWeight = pointWeight;
        this.suitWeight = suitWeight;
    }

    @Override
    public String toString() {
        return suit + point;
    }

    @Override
    public int compareTo(Card o) {
        int i = this.pointWeight.compareTo(o.pointWeight);
        switch (i) {
            case 1:
                return 1;
            case -1:
                return -1;
            case 0:
                return this.suitWeight.compareTo(o.suitWeight);
            default:
                return 0;
        }
    }
