高分求java代码 (认真回答还有悬赏)

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:

/**

private String xing; // 姓

private String ming; // 名

public String getLx() {

return lx;

}

public void setLx(String lx) {

this.lx = lx;

}

public String getXing() {

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;

}

}

/**

* 运动员得分信息

* @author songfeng163

*/

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

public String toString() {

return "** PLAYER ADDED **"+ player.toString()+"; Points:"+ spointsScored + "; Assists: "+ assists +"; Penalty Kick %:" + penaltyKickRate;

}

}

java代码

public float calSalary(){

return this.salary+this.salary*this.inc;

}

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
