用java如何判断扑克牌同花顺

扑克牌有两个属性,花色和牌面大小,可以分别比较花色和牌面大小是否递增或递减来确定是不是同花顺.但是由于扑克牌会有JQKA,所以牌面大小最好以数组或者字符串的方式实现,通过比较下标来比较大小,以下是大概的代码

public class PuKe {

private String color;

private String num;

public String getColor() {

return color;

}

public void setColor(String color) {

this.color = color;

}

public String getNum() {

return num;

}

public void setNum(String num) {

this.num = num;

}

public PuKe(String color, String num) {

super();

this.color = color;

this.num = num;

}

public static void main(String[] args) {

ListPuKecard = new ArrayListPuKe();

card.add(new PuKe("black", "2"));

card.add(new PuKe("black", "3"));

card.add(new PuKe("black", "4"));

card.add(new PuKe("black", "5"));

card.add(new PuKe("black", "6"));

//这里因为10是两位数且牌面里面用不到1,所以直接用1代替10

String check = "234567891JQKA";

boolean flage =true;

//自定义比较器,用num在check里的下标大小作为比较依据排序

Collections.sort(card, new ComparatorObject() {

@Override

public int compare(Object o1, Object o2) {

PuKe er1 = (PuKe) o1;

PuKe er2 = (PuKe) o2;

Integer org1 = (int)(er1.getNum() == null ? 0.0 : check.indexOf(er1.getNum()));

Integer org2 = (int)(er1.getNum() == null ? 0.0 : check.indexOf(er2.getNum()));

return org1.compareTo(org2);

}

});

for (int i = 0; i  card.size()-1; i++) {

//遍历所有的牌,如果颜色不一样直接跳出循环,不是同花顺

if(!card.get(i).getColor().equals(card.get(i+1).getColor())){

flage =false;

break;

}

//如果上一张减去下一张的差值不是1,说明牌面不是顺子,也不是同花顺,跳出循环

if((int)check.indexOf(card.get(i+1).getNum())-(int)check.indexOf(card.get(i).getNum())!=1){

flage = false;

break;

}

}

if(flage){

System.out.println("牌面是同花顺");

}else{

System.out.println("牌面不是同花顺");

}

}

}

不过这种方法唯一不好的地方是check中不能直接用10,将来展示的时候需要判定,展示的是1时直接改成10.

其实实现方法很多,我这么写是因为最近在复习,这么写用到的知识点相对会多一点.
