以java编写员工管理系统（测试过 无问题）

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：

package chapter03;import java.util.ArrayList;
import java.util.Scanner;public class Testemd {public static void main(String[] args) {Employee e = new Employee();ArrayList<Employee> list = new ArrayList<>();while (true) {System.out.println("|------------------------------------|");System.out.println("|------------- 1. 增加     ---------|");System.out.println("|------------- 2. 删除     ---------|");System.out.println("|------------- 3. 修改     ---------|");System.out.println("|------------- 4. 显示信息     ---|");System.out.println("|------------- 5. 查询       --------|");System.out.println("|------------- 0. 退出     ---------|");System.out.println("|------------------------------------|");System.out.print("请选择业务：");Scanner sc = new Scanner(System.in);int selectChoice = sc.nextInt();switch (selectChoice) {case 1:addEmployee(list);break;case 2:deleteEmployee(list);break;case 3:modEmployee(list);break;case 4:displayEmployee(list);break;case 5:selectEmployee(list);break;case 0:System.out.println("感谢您的使用！");System.exit(0);break;default:System.out.println("您输入的选项有误，请您重新输入！");break;}}}//添加人员public static void addEmployee(ArrayList<Employee> list){Scanner  sc = new Scanner(System.in);String  id ;while (true){System.out.print("请输入职工编号：");id = sc.next();System.out.print("请输入职工的姓名：");String name = sc.next();System.out.print("请输入职工的职务（员工、经理）：");String job = sc.next();System.out.print("请输入职工请假天数：");int holiday = sc.nextInt();System.out.print("请输入职工的基本工资：");int  baseSalary = sc.nextInt();if( job.equals("员工")){Commonemployee ce = new Commonemployee();ce.setId(id);ce.setName(name);ce.setHoliday(holiday);ce.setJob(job);ce.setbaseSalary(baseSalary);String info =  ce.toString(baseSalary,holiday,id);System.out.println(info);//将新增加的员工报存到集合中list.add(ce);System.out.println("添加成功！");//测试System.out.println("调用了添加员工的函数");break;}else  if(job.equals("经理")){Manageremployee me = new Manageremployee();me.setId(id);me.setName(name);me.setHoliday(holiday);me.setJob(job);me.setbaseSalary(baseSalary);String info =  me.toString(baseSalary,holiday,id);System.out.println(info);//将新增的员工报存到集合中去list.add(me);System.out.println("添加成功！");//测试System.out.println("调用了添加经理的函数");break;}else {System.out.println(" 您输入的有误！请您输入 员工 / 经理  ");}}}//删除操作public static void deleteEmployee(ArrayList<Employee> list){Scanner sc = new Scanner(System.in);System.out.print("请输入删除的职工号");String id = sc.next();int isExist = -1;for(int i= 0;i < list.size();i++){Employee e = list.get(i);if (e.getId().equals(id)){isExist = i;break;}}if (isExist != -1){list.remove(isExist);System.out.println("删除成功！");System.out.println("被删除的职工号为："  );}else{System.out.println("输入有误！");}}//修改操作public static void modEmployee(ArrayList<Employee>list){Scanner sc = new Scanner(System.in);System.out.println("请输入修改的职工号：");String id= sc.next();int index = -1;for(int i = 0; i < list.size();++i){Employee e = list.get(i);if (e.getId().equals(id)){index = i;break;}}if (index ==-1){System.out.println("改职工不存在！请重新输入");}else {System.out.print("请输入修改职工工姓名：");String name  = sc.next();System.out.print("请输入修改职工职务(员工/经理)：");String job  = sc.next();System.out.print("请输入原职工请假天数：");int  holiday  = sc.nextInt();System.out.print("请输入职工基本工资：");int  baseSalary  = sc.nextInt();if (job.equals("员工")){Commonemployee ce = new Commonemployee();ce.setId(id);ce.setName(name);ce.setHoliday(holiday);ce.setJob(job);ce.setbaseSalary(baseSalary);String info =  ce.toString();list.set(index,ce);System.out.println("修改成功！");}else if(job.equals("经理")){Manageremployee me = new Manageremployee();me.setId(id);me.setName(name);me.setHoliday(holiday);me.setJob(job);me.setbaseSalary(baseSalary);String info =  me.toString();System.out.println(info);list.set(index,me);System.out.println("修改成功！");}}}//显示操作public  static  void displayEmployee(ArrayList<Employee> list ){if(list.size() ==0){System.out.println("当前列表没有任何信息，请输入信息后再操作");}else {for (int i = 0; i  < list.size();++i){Employee e = list.get(i);if(e.getId().equals("员工")){System.out.println("编号为："+e.getId() +"     姓名为：" + e.getName() + "     职务为：" +e.getJob() + "    假期天数为："  + e.getHoliday() +" 天     薪资为：" +e.sumCommonEmployeeSalary(e.getbaseSalary(), e.getHoliday())+"元");} else{System.out.println("编号为："+e.getId() +"     姓名为：" + e.getName() + "     职务为：" +e.getJob() + "    假期天数为："  + e.getHoliday() +"天      薪资为：" +e.sumManagerEmployeeSalary(e.getbaseSalary(), e.getHoliday())+"元");}}}}//查询操作public static void selectEmployee(ArrayList<Employee>list){while(true) {boolean flag = false;Scanner sc = new Scanner(System.in);if (list.size() == 0) {System.out.println("当前列表没有任何信息，请输入信息后再操作");} else {System.out.print("输入查询的职工号：");String id = sc.next();for (int i = 0; i < list.size(); i++) {Employee e = list.get(i);if (e.getId().equals(id)) {System.out.println(e.toString(e.getbaseSalary(), e.getHoliday(),e.getId()));flag = true;break;}}if (flag==true){break;}System.out.println("输入的编号有错误！请重新输入！");}}}
}

 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)
