Project 2---------开发团队调度软件

该软件实现以下功能：

（1）软件启动时，根据给定的数据创建公司部分成员列表（数组）

（2）根据菜单提示，基于现有的公司成员，组建一个开发团队以开发一个新的项目

（3）组建过程包括将成员插入到团队中，或从团队中删除某成员，还可以列出团队中现有成员的列表

（4）开发团队成员包括架构师、设计师和程序员

软件设计结构：

com.atguigu.team.domain模块中包含了所有实体类：

 

 实现步骤：

一、创建项目基本组件

 1.Equipment接口及其实现子类的设计

（1）Equipment接口

public interface Equipment {
	
	String getDescription();
}

（2）PC类

public class PC implements Equipment{

	private String model;//机器型号
	private String display;//显示器名称
	
	

	public PC() {
		super();
	}

	public PC(String model, String display) {
		super();
		this.model = model;
		this.display = display;
	}

	public String getModel() {
		return model;
	}

	public void setModel(String model) {
		this.model = model;
	}

	public String getDisplay() {
		return display;
	}

	public void setDisplay(String display) {
		this.display = display;
	}
	@Override
	public String getDescription() {
		return model + "(" + display + ")";
	}
	
}

（3） NoteBook类

public class NoteBook implements Equipment{
	private String model;//机器的型号
	private double price;//价格
	
	
	public NoteBook() {
		super();
	}


	public NoteBook(String model, double price) {
		super();
		this.model = model;
		this.price = price;
	}


	public String getModel() {
		return model;
	}


	public void setModel(String model) {
		this.model = model;
	}


	public double getPrice() {
		return price;
	}

 (4)Printer类

public class Printer implements Equipment{
	private String name;//名称
	private String type;//机器的类型
	
	public Printer() {
		super();
	}

	public Printer(String name, String type) {
		super();
		this.name = name;
		this.type = type;
	}

	public String getName() {
		return name;
	}

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

	public String getType() {
		return type;
	}

	public void setType(String type) {
		this.type = type;
	}

	@Override
	public String getDescription() {
		return name + "(" + type + ")";
	}
}

2.Employee类及其子类的设计

（1）Employee类

public class Employee {
    private int id;
    private String name;
    private int age;
    private double salary;

    public Employee() {
    }

    public Employee(int id, String name, int age, double salary) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.salary = salary;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }

    protected String getDetails() {
        return id + "\t" + name + "\t" + age+ "\t" +salary;
    }

    @Override
    public String toString() {
        return getDetails();
    }
}

（2） Programmmer类

import com.atguigu.team.service.*;

public class Programmer extends Employee {
    private int memberId;
    private Status status = Status.FREE;
    private Equipment equipment;

    public Programmer() {
    }

    public Programmer(int id, String name, int age, 
                       double salary, Equipment equipment) {
        super(id, name, age, salary);
        this.equipment = equipment;
    }

    public Status getStatus() {
        return status;
    }

    public void setStatus(Status status) {
        this.status = status;
    }

    public Equipment getEquipment() {
        return equipment;
    }

    public void setEquipment(Equipment equipment) {
        this.equipment = equipment;
    }

    public int getMemberId() {
        return memberId;
    }

    public void setMemberId(int memberId) {
        this.memberId = memberId;
    }

    protected String getMemberDetails() {
        return getMemberId() + "/" + getDetails();
    }

    public String getDetailsForTeam() {
        return getMemberDetails() + "\t程序员";
    }

    @Override
    public String toString() {
        return getDetails() + "\t程序员\t" + status + "\t\t\t" + equipment.getDescription() ;
    }
}

（3） Designer类

public class Designer extends Programmer{
    private double bonus;

    public Designer() {
    }

    public Designer(int id, String name, int age, double salary, 
                     Equipment equipment, double bonus) {
        super(id, name, age, salary, equipment);
        this.bonus = bonus;
    }

    public double getBonus() {
        return bonus;
    }

    public void setBonus(double bonus) {
        this.bonus = bonus;
    }

    public String getDetailsForTeam() {
        return getMemberDetails() + "\t设计师\t" + getBonus();
    }

    @Override
    public String toString() {
        return getDetails() + "\t设计师\t" + getStatus() + "\t" +
               getBonus() +"\t\t" + getEquipment().getDescription();
    }
}

（4）Architect类

public class Architect extends Designer {
    private int stock;

    public Architect() {
    }

    public Architect(int id, String name, int age, double salary,
                      Equipment equipment, double bonus, int stock) {
        super(id, name, age, salary, equipment, bonus);
        this.stock = stock;
    }

    public int getStock() {
        return stock;
    }

    public void setStock(int stock) {
        this.stock = stock;
    }

    public String getDetailsForTeam() {
        return getMemberDetails() + "\t架构师\t" + 
               getBonus() + "\t" + getStock();
    }

    @Override
    public String toString() {
        return getDetails() + "\t架构师\t" + getStatus() + "\t" +
               getBonus() + "\t" + getStock() + "\t" + getEquipment().getDescription();
    }
}

3.Status类

package com.atguigu.team.service;
public class Status {
	private final String NAME;
	private Status(String name) {
		this.NAME = name;
	}
	public static final Status FREE = new Status("FREE");
	public static final Status VOCATION = new Status("VOCATION");
	public static final Status BUSY = new Status("BUSY");
	public String getNAME() {
		return NAME;
	}
	@Override
	public String toString() {
		return NAME;
	}
}

二、实现service包中的类 

1.NameListService类

package com.atguigu.team.service;

import com.atguigu.team.domain.*;

import static com.atguigu.team.service.Data.*;

public class NameListService {
	private Employee[] employees;

	public NameListService() {
		employees = new Employee[EMPLOYEES.length];

		for (int i = 0; i < employees.length; i++) {
			// 获取通用的属性
			int type = Integer.parseInt(EMPLOYEES[i][0]);
			int id = Integer.parseInt(EMPLOYEES[i][1]);
			String name = EMPLOYEES[i][2];
			int age = Integer.parseInt(EMPLOYEES[i][3]);
			double salary = Double.parseDouble(EMPLOYEES[i][4]);

			//
			Equipment eq;
			double bonus;
			int stock;

			switch (type) {
			case EMPLOYEE:
				employees[i] = new Employee(id, name, age, salary);
				break;
			case PROGRAMMER:
				eq = createEquipment(i);
				employees[i] = new Programmer(id, name, age, salary, eq);
				break;
			case DESIGNER:
				eq = createEquipment(i);
				bonus = Integer.parseInt(EMPLOYEES[i][5]);
				employees[i] = new Designer(id, name, age, salary, eq, bonus);
				break;
			case ARCHITECT:
				eq = createEquipment(i);
				bonus = Integer.parseInt(EMPLOYEES[i][5]);
				stock = Integer.parseInt(EMPLOYEES[i][6]);
				employees[i] = new Architect(id, name, age, salary, eq, bonus,
						stock);
				break;
			}
		}
	}

	private Equipment createEquipment(int index) {
		int type = Integer.parseInt(EQIPMENTS[index][0]);
		switch (type) {
		case PC:
			return new PC(EQIPMENTS[index][1], EQIPMENTS[index][2]);
		case NOTEBOOK:
			int price = Integer.parseInt(EQIPMENTS[index][2]);
			return new NoteBook(EQIPMENTS[index][1], price);
		case PRINTER:
			return new Printer(EQIPMENTS[index][1], EQIPMENTS[index][2]);
		}
		return null;
	}

	public Employee[] getAllEmployees() {
		return employees;
	}

	public Employee getEmployee(int id) throws TeamException {
		for (Employee e : employees) {
			if (e.getId() == id)
				return e;
		}
		throw new TeamException("该员工不存在");
	}
}

2.TeamService类 

package com.atguigu.team.service;

import com.atguigu.team.domain.*;


public class TeamService {
    private static int counter = 1;//用于自动生成团队成员的memberId
    private final int MAX_MEMBER = 5;//团队人数上限
    private Programmer[] team = new Programmer[MAX_MEMBER];//保存当前团队成员
    private int total = 0;//团队实际人数

    public TeamService() {
    }
    //返回team中所有程序员构成的数组
    public Programmer[] getTeam() {
        Programmer[] team = new Programmer[total];

        for (int i = 0; i < total; i++) {
            team[i] = this.team[i];
        }
        return team;
    }

    public void addMember(Employee e) throws TeamException {
        if (total >= MAX_MEMBER)
            throw new TeamException("成员已满，无法添加");
        if (!(e instanceof Programmer))
            throw new TeamException("该成员不是开发人员，无法添加");

        Programmer p = (Programmer)e;
        
        if (isExist(p))
        	throw new TeamException("该员工已在本团队中");
        
        if(p.getStatus().getNAME().equals("BUSY")) {
        	throw new TeamException("该员工已是某团队成员");
        }else if(p.getStatus().getNAME().equals("VOCATION")) {
        	throw new TeamException("该员正在休假，无法添加");
        }

//        switch (p.getStatus()) {
//            case BUSY    :throw new TeamException("该员工已是某团队成员");
//            case VOCATION:throw new TeamException("该员正在休假，无法添加");
//        }
        
        int numOfArch = 0, numOfDsgn = 0, numOfPrg = 0;
        for (int i = 0; i < total; i++) {
            if (team[i] instanceof Architect) numOfArch++;
            else if (team[i] instanceof Designer) numOfDsgn++;
            else if (team[i] instanceof Programmer) numOfPrg++;
        }

        if (p instanceof Architect) {
            if (numOfArch >= 1) throw new TeamException("团队中至多只能有一名架构师");
        } else if (p instanceof Designer) {
            if (numOfDsgn >= 2) throw new TeamException("团队中至多只能有两名设计师");
        } else if (p instanceof Programmer) {
            if (numOfPrg >= 3) throw new TeamException("团队中至多只能有三名程序员");
        }
        //添加到数组
        p.setStatus(Status.BUSY);
        p.setMemberId(counter++);
        team[total++] = p;
    }

    private boolean isExist(Programmer p) {
        for (int i = 0; i < total; i++) {
            if (team[i].getId() == p.getId()) return true;
        }

        return false;
    }
    //删除指定memberId的程序员
    public void removeMember(int memberId) throws TeamException {
        int n = 0;
        //找到指定memberId的员工，并删除
        for (; n < total; n++) {
            if (team[n].getMemberId() == memberId) {
                team[n].setStatus(Status.FREE);
                break;
            }
        }
        //如果遍历一遍，都找不到，则报异常
        if (n == total)
            throw new TeamException("找不到该成员，无法删除");
        //后面的元素覆盖前面的元素
        for (int i = n + 1; i < total; i++) {
            team[i - 1] = team[i];
        }
        team[--total] = null;
    }
}

3.自定义异常类： TeamException

public class TeamException extends Exception {
	static final long serialVersionUID = -33875169124229948L;

	public TeamException() {
	}

	public TeamException(String message) {
		super(message);
	}
}

三、实现view包中类

TeamView类

package com.atguigu.team.view;

import com.atguigu.team.domain.*;
import com.atguigu.team.service.*;

public class TeamView {
	private NameListService listSvc = new NameListService();
	private TeamService teamSvc = new TeamService();

	public void enterMainMenu() {
		boolean loopFlag = true;
		char key = 0;

		do {
			if (key != '1') {
				listAllEmployees();
			}
			System.out.print("1-团队列表  2-添加团队成员  3-删除团队成员 4-退出   请选择(1-4)：");
			key = TSUtility.readMenuSelection();
			System.out.println();
			switch (key) {
			case '1':
				listTeam();
				break;
			case '2':
				addMember();
				break;
			case '3':
				deleteMember();
				break;
			case '4':
				System.out.print("确认是否退出(Y/N)：");
				char yn = TSUtility.readConfirmSelection();
				if (yn == 'Y')
					loopFlag = false;
				break;
			}
		} while (loopFlag);
	}

	// 显示所有的员工成员
	private void listAllEmployees() {
		System.out
				.println("\n-------------------------------开发团队调度软件--------------------------------\n");
		Employee[] emps = listSvc.getAllEmployees();
		if (emps.length == 0) {
			System.out.println("没有客户记录！");
		} else {
			System.out.println("ID\t姓名\t年龄\t工资\t职位\t状态\t奖金\t股票\t领用设备");
		}

		for (Employee e : emps) {
			System.out.println(" " + e);
		}
		System.out
				.println("-------------------------------------------------------------------------------");
	}

	// 显示开发团队成员列表
	private void listTeam() {
		System.out
				.println("\n--------------------团队成员列表---------------------\n");
		Programmer[] team = teamSvc.getTeam();
		if (team.length == 0) {
			System.out.println("开发团队目前没有成员！");
		} else {
			System.out.println("TID/ID\t姓名\t年龄\t工资\t职位\t奖金\t股票");
		}

		for (Programmer p : team) {
			System.out.println(" " + p.getDetailsForTeam());
		}
		System.out
				.println("-----------------------------------------------------");
	}

	// 添加成员到团队
	private void addMember() {
		System.out.println("---------------------添加成员---------------------");
		System.out.print("请输入要添加的员工ID：");
		int id = TSUtility.readInt();

		try {
			Employee e = listSvc.getEmployee(id);
			teamSvc.addMember(e);
			System.out.println("添加成功");
		} catch (TeamException e) {
			System.out.println("添加失败，原因：" + e.getMessage());
		}
		// 按回车键继续...
		TSUtility.readReturn();
	}

	// 从团队中删除指定id的成员
	private void deleteMember() {
		System.out.println("---------------------删除成员---------------------");
		System.out.print("请输入要删除员工的TID：");
		int id = TSUtility.readInt();
		System.out.print("确认是否删除(Y/N)：");
		char yn = TSUtility.readConfirmSelection();
		if (yn == 'N')
			return;

		try {
			teamSvc.removeMember(id);
			System.out.println("删除成功");
		} catch (TeamException e) {
			System.out.println("删除失败，原因：" + e.getMessage());
		}
		// 按回车键继续...
		TSUtility.readReturn();
	}

	public static void main(String[] args) {
		TeamView view = new TeamView();
		view.enterMainMenu();
	}
}
