Java 类设计：Pai 类，包含价格比较方法

public class Pai { private int price; private String cl; private List pks;

public Pai(int price, String cl, List<Puke> pks) {
    this.price = price;
    this.cl = cl;
    this.pks = pks;
}

public int comparePriceTo(Pai other) {
    return this.price - other.price;
}

//getter and setter methods

}
