首先，先创建一个Gammer类与一个Poker类。
/*
* Gammer类包含int类型的id属性与String类型的name属性！
* id用int类型是为了测试后面创建用户时输入异常的情况。
*/
public class Gammer {
public int id;
public String name;
public List<Poker> pokers;
public Gammer(int id,String name){
this.id=id;
this.name=name;
this.pokers=new ArrayList<Poker>();
}
public Gammer(){
}
}/*
* Poker类包含四个属性分别为：
* String number 表示扑克牌的点数
* String colors 表示扑克牌的花色
* Integer colornb 表示扑克牌花色的大小，方便比较（用Integer类型定义，是因为用colletions.sort()方法排序的时候只能用int型的包装类）
* Integer numbernb 表示扑克牌牌面的大小，方便比较（用Integer类型定义，是因为用colletions.sort()方法排序的时候只能用int型的包装类）
*/
public class Poker implements Comparable<Poker> {
public String number;
public String colors;
public Integer colornb;
public Integer numbernb;
public Poker(String number,String colors,int colornb,int numbernb){
this.number=number;
this.colors=colors;
this.colornb=colornb;
this.numbernb=numbernb;
}
public Poker(){
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((colors == null) ? 0 : colors.hashCode());
result = prime * result + ((number == null) ? 0 : number.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (!(obj instanceof Poker))
return false;
Poker other = (Poker) obj;
if (colors == null) {
if (other.colors != null)
return false;
} else if (!colors.equals(other.colors))
return false;
if (number == null) {
if (other.number != null)
return false;
} else if (!number.equals(other.number))
return false;
return true;
}
/*
* 重写compareTo方法
* 当牌面大小不相同的时候直接比较牌面的大小
* 当牌面大小相同比较花色。
*/
@Override
public int compareTo(Poker o) {
if(this.numbernb.compareTo(o.numbernb)!=0)
return this.numbernb.compareTo(o.numbernb);
else
return this.colornb.compareTo(o.colornb);
}
}
创建一个类，改类包含了实现该练习功能的方法，方便在main函数中调用。
public class User {
public Map<Integer,Gammer> user=new HashMap<Integer,Gammer>();
public List<Poker> pokerToSelect=new ArrayList<Poker>();
