按你现在说的这个内容，我觉得三个类就能表现出来，我写了一下，你看看能不能满足你的要求：

}
public void setLx(String lx) {
this.lx = lx;
}

return xing;
}
public void setXing(String xing) {
this.xing = xing;
}
public String getMing() {
return ming;
}
public void setMing(String ming) {
this.ming = ming;
}
//返回姓名信息
@Override
public String toString() {
return xing+ming;
}
}
/**

*/
public class SoccerPlayerStats {
private PlayerState player; //运动员信息
private double spointsScored; //点球得分
private double assists; //助攻得分
private double penaltyKickRate; //罚球得分概率
public PlayerState getPlayer() {
return player;
}
public void setPlayer(PlayerState player) {
this.player = player;
}
public double getSpointsScored() {
return spointsScored;
}
public void setSpointsScored(double spointsScored) {
this.spointsScored = spointsScored;
}
public double getAssists() {
return assists;
}
public void setAssists(double assists) {
this.assists = assists;
}
public double getPenaltyKickRate() {
return penaltyKickRate;
}
public void setPenaltyKickRate(double penaltyKickRate) {
this.penaltyKickRate = penaltyKickRate;

//返回分数信息
@Override

这个方法返回一个float型，是你再Employee e = new Employee("e001","AS",5000.0f,0.1f);
赋的值，把他们的值计算，然后返回，你调用后就得到
