Java第三周-利用集合实现员工信息管理

利用集合实现员工信息管理： 
员工类（父类):

package my.employee;

public class Employee {
	//基本属性
    private String ID;
    private String name;
    private String position;
    private int holiday;
    private double salary;
    //构造方法
    public Employee(String iD,String name,String position,int holiday,double salary){
    	super();
    	this.ID=iD;
    	this.name=name;
    	this.position=position;
    	this.holiday=holiday;
    	this.salary=salary;
    }
    //get，set方法
	public String getID() {
		return ID;
	}
	public void setID(String iD) {
		ID = iD;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPosition() {
		return position;
	}
	public void setPosition(String position) {
		this.position = position;
	}
	public int getHoliday() {
		return holiday;
	}
	public void setHoliday(int holiday) {
		this.holiday = holiday;
	}
	public double getSalary() {
		return salary;
	}
	public void setSalary(double salary) {
		this.salary = salary;
	}
	//工资计算
    public double sumSalary(int holiday){
    	return 1;
    }
    //结果输出
    public void display(){
    	System.out.println("编号:"+this.ID+"姓名:"+this.name+"职务:"+this.position+"请假天数:"+this.holiday+"工资"+this.sumSalary(this.holiday));
    }
    
    
}

 董事类(子类);

public class Director extends Employee{
	//构造方法
	public Director(String iD,String name,String position,int holiday,double salary){
    	super(iD,name,position,holiday,salary);
    	this.setID(iD);
    	this.setName(name);
    	this.setPosition(position);
    	this.setHoliday(holiday);
    	this.setSalary(salary);
    }
	//工资计算
	public double sumSalary(int holiday){
		return (this.getSalary()*1.38+5000)/30*(30-this.getHoliday());
	}

}

 经理类(子类):

public class Manager extends Employee {
	//构造方法
	public Manager(String iD,String name,String position,int holiday,double salary){
    	super(iD,name,position,holiday,salary);
    	this.setID(iD);
    	this.setName(name);
    	this.setPosition(position);
    	this.setHoliday(holiday);
    	this.setSalary(salary);
    }
	//工资计算
	public double sumSalary(int holiday){
		return (this.getSalary()*1.7+500)/30*(30-this.getHoliday());
	}

 普通员工类（子类);

public class CommonEmployee extends Employee {
	//构造方法
	public CommonEmployee(String iD,String name,String position,int holiday,double salary){
    	super(iD,name,position,holiday,salary);
    	this.setID(iD);
    	this.setName(name);
    	this.setPosition(position);
    	this.setHoliday(holiday);
    	this.setSalary(salary);
    }
	//工资计算
	public double sumSalary(int holiday){
		return (this.getSalary()*1.6+200)/30*(30-this.getHoliday());
	}
}

 员工信息处理类:

import java.util.ArrayList;
import java.util.Scanner;

public class EmployeeInformationPro {
	public static ArrayList<Employee> ems=new ArrayList();

		String position=sc.nextLine();
		System.out.println("请输入员工的请假天数:");
		int holiday=sc.nextInt();
		System.out.println("请输入员工的基本工资:");
		double salary=sc.nextDouble();

	}
	public void updateEmployee(){

	public void queryEmployee(){

}

 测试类:

import java.util.Scanner;

public class TestEmployee {
    public void Menu(){
    	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 查询.-----|");
    	System.out.println("|-----0 退出.-----|");
    	System.out.println("|---------------|");
    }
    public static void main(String []args){
    	EmployeeInformationPro EIP=new EmployeeInformationPro(); 
    	TestEmployee TE=new TestEmployee();
    	Scanner sc=new Scanner(System.in);
    	TE.Menu();
    	while(true){
    	   int choose=sc.nextInt();
    	   switch(choose){
    	      case 0:
    	    	  System.exit(0);
    	    	  break;
    	      case 1:
    	    	  EIP.addEmployee();
    	    	  TE.Menu();
    	    	  break;
    	      case 2:
    	    	  EIP.delEmployee();
