一、系统结果的部分展示
二、题目以及相关要求
三、组成
1.该系统由 Employee 类 、commonEmployee类、Testemd类和managerEmployee类组成
2.Employee实现的代码
public class Employee {
private String id;
private String name;
private String job;
private int holiday;
private int baseSalary;
public Employee(String id, String name, String job, int holiday, int baseSalary) {
this.id = id;
this.name = name;
this.job = job;
this.holiday = holiday;
this.baseSalary = baseSalary;
}
public Employee() {
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public int getHoliday() {
return holiday;
}
public void setHoliday(int holiday) {
this.holiday = holiday;
}
public int getbaseSalary() {
return baseSalary;
}
public void setbaseSalary(int baseSalary) {
this.baseSalary = baseSalary;
}
public double sumCommonEmployeeSalary(int baseSalary,int holiday){ return baseSalary + baseSalary * 0.1 + baseSalary * 0.5 + 200 -(baseSalary / 20)*holiday ; }
public double sumManagerEmployeeSalary(int baseSalary,int holiday){ return baseSalary + baseSalary*0.2 + baseSalary * 0.5 + 500 - (baseSalary / 20)*holiday;}
public String toString(int baseSalary,int holiday,String ids ) {
if (ids.equals("员工")) {
return "编号为：" + getId() + " 姓名为：" + getName() + " 职务为：" + getJob() + " 请假天数为：" + getHoliday() + "天 " + getName() + "的薪资为：" + sumCommonEmployeeSalary(getbaseSalary(), getHoliday()) + "元";
} else {
return "编号为：" + getId() + " 姓名为：" + getName() + " 职务为：" + getJob() + " 请假天数为：" + getHoliday() + " 天 " + getName() + "的薪资为：" + sumManagerEmployeeSalary(getbaseSalary(), getHoliday()) + "元";
}
}
}
3. commonEmployee类的实现：
public class Commonemployee extends Employee {
public Commonemployee(String id, String name, String job, int holiday, int baseSalary) {
super(id, name, job, holiday, baseSalary);
}
public Commonemployee() {
}
}
4.managerEmployee类的实现：
public class Manageremployee extends Employee{
public Manageremployee(String id, String name, String job, int holiday, int baseSalary) {
super(id, name, job, holiday, baseSalary);
}
public Manageremployee() {
}
}
5.Testemd类的实现：

public class Testemd {
public static void main(String[] args) {

四、Congratulation：
1.首先恭喜你，是一个有进取心的人，想知道事情的底层或者原理
五、详细解释
1.对于Employee类的详解
Employee类前面的基本的JavaBean就不谈了（不知道什么是基本JavaBean去http://www.baidu.com），主要的是在求解不同类的工资时，投了一个小巧，由于commonEmployee类和managerEmployee类均是extends与Employee类的，所以在可以依据输入的职业来判断是员工还是经理，是员工直接调用sumCommonEmoployeeSalary函数否则调用sumManagerEmployeeSalary函数，然后计算相关金额，toString函数很简单就是输出相关信息。
2.对于commonEmployee类和managerEmployee类的详解
太简单了！不讲了
3.对于Testemd类的详解
该类为测试类.................(看不懂的在评论区问，懒得写了)
