基于文本界面的《开发团队调度软件》

一、功能介绍

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

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

(1)添加团队成员

①当选择“添加团队成员”菜单时，将执行从列表中添加指定（通过ID）成员到开发团队的功能

②添加成功后，按回车键将重新显示主界面

③如果添加操作因某种原因失败，将显示信息

失败信息包含以下几种：

• 成员已满，无法添加

• 该成员不是开发人员，无法添加

• 该员工已在本开发团队中

• 该员工已是某团队成员

• 该员正在休假，无法添加

• 团队中至多只能有一名架构师

• 团队中至多只能有两名设计师

• 团队中至多只能有三名程序员

（2）删除团队成员

①当选择“删除团队成员”菜单时，将执行从开发团队中删除指定（通过TeamID）成员的功能

②删除成功后，按回车键将重新显示主界面

（3）团队列表：当选择“团队列表”菜单时，将列出开发团队中的现有成员

4.开发团队成员包括架构师、设计师和程序员

二、步骤

（1）按照设计要求，创建所有包

package com.project3.service;public class Data {public static final int EMPLOYEE = 10;public static final int PROGRAMMER = 11;//程序员public static final int DESIGNER = 12;public static final int ARCHITECT = 13;public static final int PC = 21;public static final int NOTEBOOK = 22;public static final int PRINTER = 23;//Employee  :  10, id, name, age, salary//Programmer:  11, id, name, age, salary//Designer  :  12, id, name, age, salary, bonus//Architect :  13, id, name, age, salary, bonus, stockpublic static final String[][] EMPLOYEES = {{"10", "1", "马云", "22", "3000"},{"13", "2", "马化腾", "32", "18000", "15000", "2000"},{"11", "3", "李彦宏", "23", "7000"},{"11", "4", "刘强东", "24", "7300"},{"12", "5", "雷军", "28", "10000", "5000"},{"11", "6", "任志强", "22", "6800"},{"12", "7", "柳传志", "29", "10800","5200"},{"13", "8", "杨元庆", "30", "19800", "15000", "2500"},{"12", "9", "史玉柱", "26", "9800", "5500"},{"11", "10", "丁磊", "21", "6600"},{"11", "11", "张朝阳", "25", "7100"},{"12", "12", "杨致远", "27", "9600", "4800"}};//如下的EQUIPMENTS数组与上面的EMPLOYEES数组元素一一对应//PC      :21, model, display//NoteBook:22, model, price//Printer :23, name, type public static final String[][] EQUIPMENTS = {{},{"22", "联想T4", "6000"},{"21", "戴尔", "NEC17寸"},{"21", "戴尔", "三星 17寸"},{"23", "佳能 2900", "激光"},{"21", "华硕", "三星 17寸"},{"21", "华硕", "三星 17寸"},{"23", "爱普生20K", "针式"},{"22", "惠普m6", "5800"},{"21", "戴尔", "NEC 17寸"},{"21", "华硕","三星 17寸"},{"22", "惠普m6", "5800"}};
}

（2）键盘访问的实现

package com.project3.view;import java.util.*;
/*** * @Description 项目中提供了TSUtility.java类，可用来方便地实现键盘访问。* @author shkstart  Email:shkstart@126.com* @version * @date 2019年2月12日上午12:02:58**/
public class TSUtility {private static Scanner scanner = new Scanner(System.in);/*** * @Description 该方法读取键盘，如果用户键入’1’-’4’中的任意字符，则方法返回。返回值为用户键入字符。* @author shkstart* @date 2019年2月12日上午12:03:30* @return*/public static char readMenuSelection() {char c;for (; ; ) {String str = readKeyBoard(1, false);c = str.charAt(0);if (c != '1' && c != '2' &&c != '3' && c != '4') {System.out.print("选择错误，请重新输入：");} else break;}return c;}/*** * @Description 该方法提示并等待，直到用户按回车键后返回。* @author shkstart* @date 2019年2月12日上午12:03:50*/public static void readReturn() {System.out.print("按回车键继续...");readKeyBoard(100, true);}/*** * @Description 该方法从键盘读取一个长度不超过2位的整数，并将其作为方法的返回值。* @author shkstart* @date 2019年2月12日上午12:04:04* @return*/public static int readInt() {int n;for (; ; ) {String str = readKeyBoard(2, false);try {n = Integer.parseInt(str);break;} catch (NumberFormatException e) {System.out.print("数字输入错误，请重新输入：");}}return n;}/*** * @Description 从键盘读取‘Y’或’N’，并将其作为方法的返回值。* @author shkstart* @date 2019年2月12日上午12:04:45* @return*/public static char readConfirmSelection() {char c;for (; ; ) {String str = readKeyBoard(1, false).toUpperCase();c = str.charAt(0);if (c == 'Y' || c == 'N') {break;} else {System.out.print("选择错误，请重新输入：");}}return c;}private static String readKeyBoard(int limit, boolean blankReturn) {String line = "";while (scanner.hasNextLine()) {line = scanner.nextLine();if (line.length() == 0) {if (blankReturn) return line;else continue;}if (line.length() < 1 || line.length() > limit) {System.out.print("输入长度（不大于" + limit + "）错误，请重新输入：");continue;}break;}return line;}
}

（3）Equipment接口及其实现子类的设计

package com.project3.domain;public interface Equipment {public abstract String getDescription();
}

package com.project3.domain;public class PC implements Equipment{private String model;//机器的型号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;}@Overridepublic String getDescription() {return model + "(" + display + ")";}}

package com.project3.domain;public class NoteBook implements Equipment{private String model;private double price;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;}public void setPrice(double price) {this.price = price;}@Overridepublic String getDescription() {return model + "(" + price + ")";}}

package com.project3.domain;public class Printer implements Equipment{private String name;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;}@Overridepublic String getDescription() {return name + "(" + type + ")";}}

}

package com.project3.domain;import java.util.jar.Attributes.Name;import com.project3.service.Status;public class Programmer extends Employee{private int memberId;//成员加入开发团队后在团队中的IDprivate Status status = Status.FREE;private Equipment equipment;//设备public int getMemberId() {return memberId;}public void setMemberId(int memberId) {this.memberId = memberId;}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 Programmer() {super();}public Programmer(int id, String name, int age, double salary, Equipment equipment) {super(id, name, age, salary);this.equipment = equipment;}@Overridepublic String toString() {return getDetails() + "\t程序员\t" + status + "\t	 \t" + equipment.getDescription();}public String getTeamBaseDetails() {return memberId + "/" + getId() + "\t" + getName() + "\t" + getAge() + "\t" + getSalary();}public String getDetailsForTeam() {return  getTeamBaseDetails() + "\t程序员"; }
}

package com.project3.domain;import com.project3.service.Status;public class Designer extends Programmer{private double bonus;//奖金public double getBonus() {return bonus;}public void setBonus(double bonus) {this.bonus = bonus;}public Designer() {super();}public Designer(int id, String name, int age, double salary, Equipment equipment, double bonus) {super(id, name, age, salary, equipment);this.bonus = bonus;}@Overridepublic String toString() {return getDetails() + "\t设计师\t"  + getStatus() + "\t" + bonus + "\t\t" + getEquipment().getDescription();}public String getDetailsForTeam() {return getTeamBaseDetails() + "\t设计师" + "\t" + getBonus(); }
}

package com.project3.domain;public class Architect extends Designer{private int stock;//表示公司奖励的股票数量public int getStock() {return stock;}public void setStock(int stock) {this.stock = stock;}public Architect() {super();}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;}@Overridepublic String toString() {return getDetails() + "\t架构师\t"  + getStatus() + "\t" + getBonus() + "\t" + stock + "\t" + getEquipment().getDescription();}public String getDetailsForTeam() { return getTeamBaseDetails() + "\t架构师" + getBonus() + "\t" + getStock(); }
}

package com.project3.service;
/*** * @Description 员工的状态* @author liermin Email:779679458@qq.com* @version* @date Oct 17, 2022 11:23:18 AM**/
