package ti;
/*

*/
员工类:
public class Employee {
private String name;
private String id;
private double cunKuan;
private double gongZi;

public Employee() {
}

public Employee(String name, String id, double cunKuan, double gongZi) {
    this.name = name;
    this.id = id;
    this.cunKuan = cunKuan;
    this.gongZi = gongZi;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public double getCunKuan() {
    return cunKuan;
}

public void setCunKuan(double cunKuan) {
    this.cunKuan = cunKuan;
}

public double getGongZi() {
    return gongZi;
}

public void setGongZi(double gongZi) {
    this.gongZi = gongZi;
}
 @Override
public String toString() {
    return "Employee{" +
            "name='" + name + '\'' +
            ", id='" + id + '\'' +
            ", cunKuan=" + cunKuan +
            ", gongZi=" + gongZi +
            '}';
}

}

厨师类:
package ti;

public class chuShi extends Employee{
public chuShi() {
}

public chuShi(String name, String id, double cunKuan, double gongZi) {
    super(name, id, cunKuan, gongZi);
}

}
经理类:
package ti;
/经理在员工基础上添加奖金属性/
public class Manger extends Employee {
private double jingJin;

public Manger() {
}


public Manger(String name, String id, double cunKuan, double gongZi, double jingJin) {
    super(name, id, cunKuan, gongZi);
    this.jingJin = jingJin;
}

public double getJingJin() {
    return jingJin;
}

public void setJingJin(double jingJin) {
    this.jingJin = jingJin;
}

}

服务员类:
package ti;

public class waiter extends Employee{
public waiter() {
}

public waiter(String name, String id, double cunKuan, double gongZi) {
    super(name, id, cunKuan, gongZi);
}

}

package ti;

import jdk.nashorn.internal.ir.CallNode;

import java.util.ArrayList;

公司类:

public class Company {
private double zongZiChan;
private ArrayList list;

public Company() {
}

public Company(double zongZiChan, ArrayList<Employee> list) {
    this.zongZiChan = zongZiChan;
    this.list = list;
}
 public void show(){
         System.out.println("公司的总资产:" + zongZiChan);
     System.out.println("______________________________________________");
        for (int i = 0; i < list.size(); i++) {
         Employee ee = list.get(i);
         System.out.println("员工的名字:" + ee.getName());
         System.out.println("员工的工号:" + ee.getId());
         System.out.println("员工的工资:" + ee.getGongZi());
         System.out.println("员工的存款:" + ee.getCunKuan());
         if (ee instanceof Manger) {
             System.out.println("员工的职位是经理");
             System.out.println("经理的奖金是"+((Manger) ee).getJingJin());

         }
         System.out.println("__________________________________________");
     }

 }

public double getZongZiChan() {
    return zongZiChan;
}

public void setZongZiChan(double zongZiChan) {
    this.zongZiChan = zongZiChan;
}

public ArrayList<Employee> getList() {
    return list;
}

public void setList(ArrayList<Employee> list) {
    this.list = list;
}
 public void faGongZi(){
     for (int i = 0; i < list.size(); i++) {
         Employee ee = list.get(i);
         double gongZi = ee.getGongZi();//遍历之后得到的员工工资
         zongZiChan=zongZiChan-gongZi;//公司的总资产=总资产-员工的工资
         ee.setCunKuan(ee.getGongZi()+ee.getCunKuan());//员工的工资=员工的存款+现在的工资

         if(ee instanceof  Manger){
             zongZiChan=zongZiChan-((Manger) ee).getJingJin();
             ee.setCunKuan( ee.getCunKuan()+((Manger) ee).getJingJin());
         }

     }

 }
 public Employee xingyun(){
     Random random = new Random();
     int index = random.nextInt(list.size());
     Employee employee = list.get(index);
     return  employee;


 }

}

测试类:
package ti;

import day11.demo05.GongSi;

import java.util.ArrayList;

public class Text {
public static void main(String[] args) {
double zongZiChan=10000;
chuShi chu = new chuShi(“小明”,“001”,5000,2000);
Manger ma= new Manger(“小红”,“002”,7000,3000,500);
waiter wai = new waiter(“小刚”,“003”,4000,3500);
ArrayList list = new ArrayList<>();
list.add(chu);
list.add(ma);
list.add(wai);
Company com = new Company(zongZiChan,list);
com.show();
com.faGongZi();
System.out.println("__发工资后");
com.show();
System.out.println("_幸运之星");
Employee xingyun = com.xingyun();
System.out.println(xingyun);
