【Java】JavaSE实践项目完整版（含代码）

在开始动手前先进行需求分析和模型设计。

需求分析：

先看看我们所需要的系统功能结构：

这个项目简单来说需要完成用户、开发人员、开发团队和开发项目的增删改查，在完成相应的功能之后还要与用户交互实现即设计好交互界面，能够让用户访问新项目内容，使用相关功能。

系统流程如下：

• 模拟实现一个基于文本界面的 《 项目开发团队分配管理软件 》 • 熟悉 Java 面向对象的高级特性，进一步掌握编程技巧和调试技巧 • 主要涉及以下知识点： ① 类的继承性和多态性 ② 对象的值传递、接口 ③ static 和 final 修饰符 ④ 特殊类的使用：包装类、抽象类、内部类 ⑤ 异常处理 ⑥ Java 基本语法和流程控制 ⑦ 数组， ArrayList 集合

三大模块之间的联系如下：

① com.team.view    模块为主控模块，负责菜单的显示和处理用户操作 ② com.team.service  模块为实体对象（ Employee 及其子类如程序员等）的管理模块， NameListService 和 TeamService 类分别用各自的数组来管理公司员工和开发团队成员对象 ③ ProjectService 是对项目的操作对象类       ④ domain 模块为 Employee 及其子类等 JavaBean 类所在的包 梳理完毕之后开始分模块进行设计和代码实现： 先准备好八个实体类和一个接口： 七个实体类分别是：员工、程序员、设计师、架构师、电脑、打印机、型号类、项目类； 还有一个接口， 实现类实现接口的方法，返回各自属性的信。 如图所示：

结构如下：

 

 每个类的代码如下，写法大同小异，个别类存在继承关系：

先写要实现的结构以及接口内的方法：

接口代码如下： package com.team.domain; //接口 public interface Equipment { String getDescription(); } 之后是employee员工类： package com.team.domain; //员工类 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 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 int getAge() { return age; } public void setAge(int age) { this.age = age; } public double getSalary() { return salary; } public void setSalary(double salary) { this.salary = salary; } //实现接口，返回属性信； @Override public String toString() { return id + "\\t" + name + "\\t" + age + "\\t\\t" + salary; } } 程序员类是员工类的子类，他们存在继承关系，程序员属于员工类型的一种。 package com.team.domain; //程序员类 public class Programmer extends Employee { private int memberId; private boolean status=true;//人员的状态初始化为true，添加到团队之后为false； private Equipment equipment;//成员设备 public Programmer(){} public Programmer(int id, String name, int age, double salary, Equipment equipment) { super(id, name, age, salary); this.equipment = equipment; } public int getMemberId() { return memberId; } public void setMemberId(int memberId) { this.memberId = memberId; } public boolean isStatus(){return status;} public void setStatus(boolean status) { this.status = status; } public Equipment getEquipment() { return equipment; } } 设计师类继承程序员类： package com.team.domain; //设计师类 public class Designer extends Programmer { private double bonus;//奖金 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; } }

架构师类同理： package com.team.domain; //架构师类 public class Architect extends Designer { private int stock;//公司奖励的股票； 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; } }

之后是以上实体所领用的设备类：

首先是电脑类：电脑类包含设备信（电脑的型号和显示器）并实现接口返回设备信。 package com.team.domain; //电脑类 public class PC implements Equipment { private String model;//电脑型号 private String display;//显示器 public PC(){} public PC(String model, String display) { this.model = model; this.display = display; } @Override public String getDescription() { return model + "(" + display + ")"; } } 打印机类同理： package com.team.domain; //打印机类 public class Print implements Equipment { private String name;//机器名称 private String type;//类型 public Print(){} public Print(String name, String type) { this.name = name; this.type = type; } @Override public String getDescription() { return name+ "(" +type+ ")" ; } } 还有一个型号类： package com.team.domain; public class NoteBook implements Equipment { private String model;//机器型号 private double price;//价格 public NoteBook(){} public NoteBook(String model, double price) { this.model = model; this.price = price; } @Override public String getDescription() { return model + "(" + price + ")"; } }

项目类：包含项目的编号、名称、开发团队、开发团队名称以及开发状态这几个属性

package com.team.domain; import java.util.Arrays; //项目类 public class Project { private int proId;//项目号 private String projectName;//项目名称 private String desName;//项目描述 private Programmer[] team;//开发团队 private String teamName;//开发团队名称 private boolean status;//开发状态（true为开发中，false为未开发中） public Project(int proId, String projectName, Programmer[] team, String teamName,String desName, boolean status) { this.proId = proId; this.projectName = projectName; this.desName=desName; this.team = team; this.teamName = teamName; this.status = status; } public int getProId() { return proId; } public void setProId(int proId) { this.proId = proId; } public String getProjectName() { return projectName; } public void setProjectName(String projectName) { this.projectName = projectName; } public Programmer[] getTeam() { return team; } public void setTeam(Programmer[] team) { this.team = team; } public String getTeamName() { return teamName; } public void setTeamName(String teamName) { this.teamName = teamName; } public boolean isStatus() { return status; } public void setStatus(boolean status) { this.status = status; } @Override public String toString() { return "项目{" + "项目号=" + proId + ", 项目名称='" + projectName + '\\'' + ", 开发团队=" + Arrays.toString(team) + ", 开发团队名称='" + teamName + '\\'' + ", 开发状态=" + status + '}'; } }

这样八个实体类和一个接口就搞定了，domain模块完成！

搞定^_^！

 实体和接口准备完毕之后可以进行各个功能的实现了！

用户的登录和注册：

需求如下：

• 定义一个 LoginView 类 • 实现注册方法 • 如果没有账户则需要注册 • 如果有账号则直接进行登录 • 实现登录功能 • 判断用户输入的值是否正确 • 如果正确则进入软件菜单 • 如果错误则重新输入，限制次数只有 5 次，超过次数则程序停止，重新启动 • 实现修改用户密码功能 • 可以实现对用户名，密码，或者两者都可以进行修改即可。

与之相关的类是loginView和loginService，根据需求实现相关功能。

LoginView：设计用户登录注册界面，其中还调用了TSUtility中的方法 package com.team.view; import com.team.service.LoginService; import java.util.Scanner; public class LoginView { private Scanner sc = new Scanner(System.in); private LoginService loginService = new LoginService(); //软件初始界面 public void initMenu() { boolean flag = true; int i = 0; while (flag) { System.out.println("☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆"); System.out.println("\\t欢迎来到项目开发团队分配管理软件"); System.out.println("☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆"); if (i == 0) { System.out.println("\\uD83D\\uDC15\\n\\uD83D\\uDC15"); System.out.println("\\uD83D\\uDC15-----<请先注册或登录>-----\\uD83D\\uDC15"); TSUtility.readReturn(); } System.out.print("1.登录\\t2.注册\\t3.退出软件\\n请选择："); char c = TSUtility.readInitMenuSelection(); switch (c) { case '1': loginMenu(); flag = false; break; case '2': registerMenu(); break; case '3': System.out.print("确认是否退出(Y/N)："); char rcs = TSUtility.readConfirmSelection(); if (rcs == 'Y') { System.exit(0); } } i++; } } //登录界面(仅供本类initMenu()方法调用) private void loginMenu() { for (int i = 0; i < 5; i++) { System.out.println("===================="); System.out.println("==\\t 登录界面\\t =="); System.out.println("===================="); System.out.println("请输入用户名："); String userName = sc.nextLine(); System.out.println("请输入密码："); String password = sc.nextLine(); if (loginService.login(userName, password)) { try { TSUtility.loadSpecialEffects(); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("登录成功！欢迎您：" + userName); break; } else { //如果错误则重新输入，限制次数只有5次，超过次数则程序停止，重新启动 System.out.println("登录失败！用户名或密码错误！"); if (i == 4) { System.out.println("登录次数还剩0次，软件已停止运行，请重新启动！"); System.exit(0); } System.out.println("登录次数还剩" + (4 - i) + "次，请重新输入！"); } } } //注册界面(仅供本类initMenu()方法调用) private void registerMenu() { System.out.println("===================="); System.out.println("==\\t 注册界面\\t =="); System.out.println("===================="); System.out.println("请输入你要注册的用户名："); String userName = sc.nextLine(); System.out.println("请输入你要注册的密码："); String password = sc.nextLine(); loginService.register(userName, password); System.out.println("注册成功！请登录！"); } //用户信修改界面 public void modifyMenu() { while (true) { System.out.println("===================="); System.out.println("==\\t 修改界面\\t =="); System.out.println("===================="); System.out.println("请输入你需要修改的类型："); System.out.println("1(修改用户名)"); System.out.println("2(修改密码)"); System.out.println("3(修改用户名和密码)"); System.out.println("4(不修改，退出)"); char s = TSUtility.readMenuSelection(); if (s == '1' || s == '3') { System.out.println("请输入新的用户名："); if (loginService.modifyUserName(sc.nextLine())) { System.out.println("修改成功！"); } else { System.out.println("修改失败！"); } } if (s == '2' || s == '3') { System.out.println("请输入新的密码："); if (loginService.modifyPassword(sc.nextLine())) { System.out.println("修改成功！"); } else { System.out.println("修改失败！"); } } if (s == '4') { System.out.println("退出中"); try { TSUtility.loadSpecialEffects(); } catch (InterruptedException e) { e.printStackTrace(); } break; } } } }

其中Ud83D属于Unicode编码

emojji表情符号中的一个，这里对应的是如图所示的图标。

Unicode码：Unicode码也是一种国际标准编码，采用二个字节编码，与ASCII码不兼容。目前，在网络、Windows系统和很多大型软件中得到应用。

效果如图所示：

TSUtility内容如下，包含LoginView调用的方法： package com.team.view; import java.util.Random; import java.util.Scanner; public class TSUtility { private static Scanner scanner = new Scanner(System.in); public static char readInitMenuSelection() { char c; for (; ; ) { String str = readKeyBoard(1, false); c = str.charAt(0); if (c != '1' && c != '2' && c != '3') { System.out.print("选择错误，请重新输入："); } else break; } return c; } 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; } public static char readMenuSelectionPro() { char c; for (; ; ) { String str = readKeyBoard(1, false); c = str.charAt(0); if (c != '1' && c != '2' && c != '3' && c != '4' && c != '5') { System.out.print("选择错误，请重新输入："); } else break; } return c; } public static void readReturn() { System.out.print("按回车键继续..."); readKeyBoard(100, true); } 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; } public static int readStock() { int n; for (; ; ) { String str = readKeyBoard(6, 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; } public static Double readDouble() { Double n; for (; ; ) { String str = readKeyBoard(6, false); try { n = Double.parseDouble(str); break; } catch (NumberFormatException e) { System.out.print("数字输入错误，请重新输入："); } } return n; } 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; } public static String readString(int limit, String defaultValue) { String str = readKeyBoard(limit, true); return str.equals("") ? defaultValue : str; } public 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; } public static void loadSpecialEffects() throws InterruptedException { System.out.println("请稍等："); for (int i1 = 1; i1 <= 100; i1++) { System.out.print("加载中：" + i1 + "%"); Thread.sleep(new Random().nextInt(25) + 1); if (i1 == 100) { Thread.sleep(50); } System.out.print("\\r"); } } } LoginService内容如下：实现用户登录和注册的功能。

//实现注册功能

    public void register(String userName, String password) {         String[] user = {userName, password};         users.add(user);     }

    //实现登录功能

    public boolean login(String userName, String password) {         for (int i = 0; i < users.size(); i++) {             if (users.get(i)[0].equals(userName) && users.get(i)[1].equals(password)) {                 currentUser = users.get(i);                 return true;             }         }         return false;     }

注册登录部分包含修改用户名密码部分完整代码如下：

package com.team.service; import sun.security.util.Password; import java.util.ArrayList; public class LoginService { private ArrayList<String[]> users = new ArrayList<>(); private String[] currentUser; //实现注册功能 public void register(String userName, String password) { String[] user = {userName, password}; users.add(user); } //实现登录功能 public boolean login(String userName, String password) { for (int i = 0; i < users.size(); i++) { if (users.get(i)[0].equals(userName) && users.get(i)[1].equals(password)) { currentUser = users.get(i); return true; } } return false; } //实现修改用户名功能 public boolean modifyUserName(String userName) { for (int i = 0; i < users.size(); i++) { if (currentUser == users.get(i)) { users.get(i)[0] = userName; return true; } } return false; } //实现修改密码功能 public boolean modifyPassword(String password) { for (int i = 0; i < users.size(); i++) { if (currentUser == users.get(i)) { users.get(i)[1] = password; return true; } } return false; } } 开发人员管理模块：

需求如下：

• 在 NameListService 类中完成功能操作 • 实现员工的添加 ( 根据职业添加（无，程序员，设计师，架构师） ) • 实现员工的修改（至少修改员工的姓名，年龄，工资） • 实现员工的删除（注意员工 id 需要动态显示，也就是删除后，员工 id 需要更新） • 实现员工的查看 （显示所有数据）

自定义异常类TeamException：

代码如下：

public class TeamException extends Exception { public TeamException() { } public TeamException(String message) { super(message); } }

根据NameListService结构写代码：包含开发人员的增删改查以及初始人员设置。

初始化员工设置的代码块：为了美观我使用\\t进行调整。

根据employee中对应职位的属性在代码块中进行赋值，不过比较可惜的是我还没有学到数据库，因为没有接入数据库程序每次运行上一次运行的修改均不会保留，反复测试各个模块的功能相应地也变得麻烦尤其是在调整开发初始人员界面的时候。

{ employees.add(new Employee(1, "马云 \\t", 22,3000)); employees.add(new Architect(2, "马化腾 \\t", 32, 18000, new NoteBook("联想T4", 6000), 60000, 5000)); employees.add(new Programmer(3, "李彦宏 \\t", 23, 7000, new PC("戴尔", "NEC 17寸"))); employees.add(new Programmer(4, "刘强东 \\t", 24, 7300, new PC("戴尔", "三星 17寸"))); employees.add(new Designer(5, "雷军 \\t", 50, 10000, new Print("激光", "佳能2900"), 5000)); employees.add(new Programmer(6, "任志强 \\t", 30, 16800, new PC("华硕", "三星 17寸"))); employees.add(new Designer(7, "柳传志 \\t", 45, 35500, new PC("华硕", "三星 17寸"), 8000)); employees.add(new Architect(8, "杨元庆 \\t", 35, 6500, new Print("针式", "爱普生20k"), 15500, 1200)); employees.add(new Designer(9, "史玉柱 \\t", 27, 7800, new NoteBook("惠普m6", 5800), 1500)); employees.add(new Programmer(10, "丁磊 \\t", 26, 6600, new PC("戴尔", "NEC17寸"))); employees.add(new Programmer(11, "张朝阳 \\t", 35, 7100, new PC("华硕", "三星 17寸"))); employees.add(new Designer(12, "杨致远 \\t", 38, 9600, new NoteBook("惠普m6", 5800), 3000)); } 员工的增删改查： //查看指定id的员工； public ArrayList<Employee>getEmployees(){ return employees; } public Employee getEmployees(int id) throws TeamException{ for (Employee employee:employees){//增强for循环 if (employee.getId()==id){ return employee; } } throw new TeamException("找不到该员工，请确认id是否输入正确！"); } //添加员工,根据职业添加 public void addEmployee(char c,String name,int age,double salary,Equipment equipment,double bonus, int stock) { switch (c){ case '1': employees.add(new Employee(employees.size() + 1, name, age, salary)); break; case '2': employees.add(new Programmer(employees.size() + 1, name, age, salary, equipment)); break; case '3': employees.add(new Designer(employees.size() + 1, name, age, salary, equipment, bonus)); break; case '4': employees.add(new Architect(employees.size() + 1, name, age, salary, equipment, bonus, stock)); break; } } //修改员工 public void modifyEmployee(Employee employee,String name,int age,double salary){ employee.setName(name); employee.setAge(age); employee.setSalary(salary); } //实现员工的删除（注意员工id需要动态显示，也就是删除后，员工id需要更新） public boolean deleteEmployee(int id){ //如果没有该员工则输出异常信 try { employees.remove(getEmployees(id)); }catch (TeamException e){ System.out.println(e.getMessage()); return false;} for (int i=0;i<employees.size();i++){ employees.get(i).setId(i+1);} return true; } 完整代码如下： package com.team.service; import com.team.domain.*; import java.util.ArrayList; public class NameListService { private ArrayList<Employee>employees=new ArrayList<>(); //代码块，初始化员工数据 { employees.add(new Employee(1, "马云 \\t", 22,3000)); employees.add(new Architect(2, "马化腾 \\t", 32, 18000, new NoteBook("联想T4", 6000), 60000, 5000)); employees.add(new Programmer(3, "李彦宏 \\t", 23, 7000, new PC("戴尔", "NEC 17寸"))); employees.add(new Programmer(4, "刘强东 \\t", 24, 7300, new PC("戴尔", "三星 17寸"))); employees.add(new Designer(5, "雷军 \\t", 50, 10000, new Print("激光", "佳能2900"), 5000)); employees.add(new Programmer(6, "任志强 \\t", 30, 16800, new PC("华硕", "三星 17寸"))); employees.add(new Designer(7, "柳传志 \\t", 45, 35500, new PC("华硕", "三星 17寸"), 8000)); employees.add(new Architect(8, "杨元庆 \\t", 35, 6500, new Print("针式", "爱普生20k"), 15500, 1200)); employees.add(new Designer(9, "史玉柱 \\t", 27, 7800, new NoteBook("惠普m6", 5800), 1500)); employees.add(new Programmer(10, "丁磊 \\t", 26, 6600, new PC("戴尔", "NEC17寸"))); employees.add(new Programmer(11, "张朝阳 \\t", 35, 7100, new PC("华硕", "三星 17寸"))); employees.add(new Designer(12, "杨致远 \\t", 38, 9600, new NoteBook("惠普m6", 5800), 3000)); } //查看指定id的员工； public ArrayList<Employee>getEmployees(){ return employees; } public Employee getEmployees(int id) throws TeamException{ for (Employee employee:employees){//增强for循环 if (employee.getId()==id){ return employee; } } throw new TeamException("找不到该员工，请确认id是否输入正确！"); } //添加员工,根据职业添加 public void addEmployee(char c,String name,int age,double salary,Equipment equipment,double bonus, int stock) { switch (c){ case '1': employees.add(new Employee(employees.size() + 1, name, age, salary)); break; case '2': employees.add(new Programmer(employees.size() + 1, name, age, salary, equipment)); break; case '3': employees.add(new Designer(employees.size() + 1, name, age, salary, equipment, bonus)); break; case '4': employees.add(new Architect(employees.size() + 1, name, age, salary, equipment, bonus, stock)); break; } } //修改员工 public void modifyEmployee(Employee employee,String name,int age,double salary){ employee.setName(name); employee.setAge(age); employee.setSalary(salary); } //实现员工的删除（注意员工id需要动态显示，也就是删除后，员工id需要更新） public boolean deleteEmployee(int id){ //如果没有该员工则输出异常信 try { employees.remove(getEmployees(id)); }catch (TeamException e){ System.out.println(e.getMessage()); return false;} for (int i=0;i<employees.size();i++){ employees.get(i).setId(i+1);} return true; } } 开发团队调度管理：

需求如下：开发团队的增删改查：

失败信包含以下几种：  (需要抛出自定义异常,上文已经自定义异常了，用那个就行)

– 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 – 团队中至多只能有一名架构师（以下判断可借用 instanceof 进行判断） – 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

包含TeamView和TeamService两个类。其中TeamService和TeamView还需要调用TSUtility中的方法进行增删改查。

根据需求设计类的大致内容：

对项目进行修改，分配团队等等……

ProjectView和ProjectService和Project三个类与之相关。

根据此需求设计ProjectView和ProjectService。结构如下：

 ProjectView：项目管理界面设计

设计界面并初始化项目。

package com.team.view; import com.team.domain.Architect; import com.team.domain.Designer; import com.team.domain.Programmer; import com.team.domain.Project; import com.team.service.ProjectService; import java.util.ArrayList; import java.util.Random; import java.util.Scanner; public class ProjectView { private ProjectService proSvc = new ProjectService(); private ArrayList<Programmer[]> allTeam = TeamView.TeamSvc.getAllTeam(); private ArrayList<String> teamNames = new ArrayList<>(); //保存所有团队名称 private ArrayList<Integer> assignedTeam = new ArrayList<>(); //保存已分配项目的团队的索引 private Scanner sc = new Scanner(System.in); private Random r = new Random(); //开发项目管理主菜单 public void projectManageMainMenu() { while (true) { System.out.println("🔣 ~开发项目管理主菜单~ 🔣"); System.out.println("🐕1. <项目的添加> *"); System.out.println("🐖2. <项目分配开发团队> *"); System.out.println("🐱3. <项目的查看> *"); System.out.println("🐂4. <项目的删除> *"); System.out.println("🐇5. <退出当前菜单> *"); System.out.print("⬇请选择："); switch (TSUtility.readMenuSelectionPro()) { case '1': addProjectView(); break; case '2': dealingProView(); break; case '3': try { TSUtility.loadSpecialEffects(); } catch (InterruptedException e) { e.printStackTrace(); } showPro(); break; case '4': delProView(); break; case '5': System.out.print("确认是否退出(Y/N)："); if (TSUtility.readConfirmSelection() == 'Y') { return; } break; } } } /* 以下四个方法（addProjectView、dealingProView、showPro、delProView）仅供本类projectManageMainMenu()方法调用 */ //项目的添加交互界面 private void addProjectView() { System.out.println("项目参考：--------------------------------------------"); System.out.println("1.小米官网：开发完成类似于小米官网的web项目."); System.out.println("2.公益在线商场：猫宁Morning公益商城是中国公益性在线电子商城."); System.out.println("3.博客系统：Java博客系统，让每一个有故事的人更好的表达想法！"); System.out.println("4.在线协作文档编辑系统：一个很常用的功能，适合小组内的文档编辑."); System.out.println("----------------------------------------------------"); TSUtility.readReturn(); System.out.println("请输入你想添加的项目编号："); char num = TSUtility.readMenuSelection(); try { TSUtility.loadSpecialEffects(); } catch (InterruptedException e) { e.printStackTrace(); } if (!proSvc.addProject(num)) { System.out.println("该项目已添加，请勿重复添加！"); } } //项目分配开发团队交互界面 private void dealingProView() { if (proSvc.getPro().size() == 0) { System.out.println("没有项目，请先添加项目！"); return; } if (!proSvc.isNotDeveloped()) { System.out.println("没有未被开发的项目，请先添加项目！"); return; } if (assignedTeam.size() == allTeam.size()) { System.out.println("没有可分配的空闲团队！"); return; } for (int i = 0; i < allTeam.size(); i++) { if (assignedTeam.contains(i)) { continue; } System.out.println("当前团队有人员："); for (Programmer p : allTeam.get(i)) { if (p instanceof Architect) { Architect a = (Architect) p; System.out.println(a + "\\t架构师\\t" + a.isStatus() + "\\t" + a.getBonus() + "\\t" + a.getStock() + "\\t" + a.getEquipment().getDescription()); } else if (p instanceof Designer) { Designer d = (Designer) p; System.out.println(d + "\\t设计师\\t" + d.isStatus() + "\\t" + d.getBonus() + "\\t\\t\\t" + d.getEquipment().getDescription()); } else { System.out.println(p + "\\t程序员\\t" + p.isStatus() + "\\t\\t\\t\\t\\t" + p.getEquipment().getDescription()); } } System.out.println("请为当前团队创建一个团队名称："); teamNames.add(sc.nextLine()); } while (true) { int index = r.nextInt(allTeam.size()); if (assignedTeam.contains(index)) { continue; } if (proSvc.dealingPro(allTeam.get(index), teamNames.get(index))) { assignedTeam.add(index); } else { return; } if (assignedTeam.size() == allTeam.size()) { return; } } } //项目的查看 private void showPro() { ArrayList<Project> pro = proSvc.getPro(); if (pro.size() == 0) { System.out.println("没有项目，请先添加！"); return; } for (Project p : pro) { if (p.isStatus()) { System.out.println("项目【" + p.getProjectName() + "】---->正在被团队【" + p.getTeamName() + "】开发中！"); } else { System.out.println(p + "\\n项目【" + p.getProjectName() + "】---->未被开发！"); } } } //项目的删除交互界面 private void delProView() { System.out.print("请输入需要删除的项目id："); int proId = TSUtility.readInt(); if (proId < 1 || proId > proSvc.getPro().size()) { System.out.println("你输入的项目id有误，删除失败！"); return; } if (proSvc.getPro().get(proId - 1).isStatus()) { System.out.println("项目正在开发中！删除失败！"); return; } proSvc.delPro(proId); System.out.println("删除成功！"); } }

ProjectService：项目的增删改查

package com.team.service; import com.team.domain.Programmer; import com.team.domain.Project; import java.util.ArrayList; public class ProjectService { private ArrayList<Project>pro=new ArrayList<>(); private int count=1; //添加项目 public boolean addProject(char num) { switch (num) { case '1': if (isAdded("小米官网")) { return false; } pro.add(new Project(count++, "小米官网", null, null, "开发完成类似于小米官网的web项目.", false)); break; case '2': if (isAdded("公益在线商场")) { return false; } pro.add(new Project(count++, "公益在线商场", null, null, "猫宁Morning公益商城是中国公益性在线电子商城.", false)); break; case '3': if (isAdded("博客系统")) { return false; } pro.add(new Project(count++, "博客系统", null, null, "Java博客系统，让每一个有故事的人更好的表达想法！", false)); break; case '4': if (isAdded("在线协作文档编辑系统")) { return false; } pro.add(new Project(count++, "在线协作文档编辑系统", null, null, "一个很常用的功能，适合小组内的文档编辑.", false)); break; } System.out.println("已添加项目：" + pro.get(count - 2).getProjectName()); return true; } //给项目分配开发团队 public boolean dealingPro(Programmer[]team,String teamName){ for (Project p:pro){ if (!p.isStatus()){ p.setTeam(team); p.setTeamName(teamName); p.setStatus(true); return true; } } return false; } //查看项目 public ArrayList<Project>getPro(){return pro;} //删除项目 public void delPro(int proId){ pro.remove(proId-1); for (int i=proId;i<pro.size();i++){ pro.get(i).setProId(pro.get(i).getProId()-1); } count--; } //判断是否有未被开发的项目（true有，false无） public boolean isNotDeveloped(){ for (Project p:pro){ if (!p.isStatus()){ return true; } } return false; } //判断项目是否已经被添加到集合中（仅供本类addProject方法调用） private boolean isAdded(String projectName){ for (Project p:pro){ if (p.getProjectName().equals(projectName)){ return true; } } return false; } } 主程序模块：IndexView：将用户管理、团队管理、项目管理、人员调度四个模块衔接在一起并设计主菜单界面。 package com.team.view; /* 软件主界面类（将4个模块衔接在一起） */ public class IndexView { private static LoginView lv = new LoginView(); private static NameListView nlv = new NameListView(); private static TeamView tv = new TeamView(); private static ProjectView pv = new ProjectView(); /* 颜色特效 */ public static final String ANSI_RESET = "\\u001B[0m"; public static final String ANSI_BLUE = "\\u001B[34m"; public static void main(String[] args) { IndexView iv = new IndexView(); lv.initMenu(); iv.softwareMainMenu(); } //软件主菜单 private void softwareMainMenu() { while (true) { System.out.println(ANSI_RESET + ANSI_BLUE); System.out.println("🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣"); System.out.println("🔣 🔣"); System.out.println("🔣 ~软件主菜单~ 🔣"); System.out.println("🔣 🔣"); System.out.println("🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣🔣"); System.out.println("🐻1. <用户信修改> *"); System.out.println("🐘2. <开发人员管理> *"); System.out.println("🦁3. <开发团队调度管理> *"); System.out.println("🐻4. <开发项目管理> *"); System.out.println("🦊5. <退出软件> *"); System.out.println("⬇请选择： "); System.out.print(ANSI_RESET); switch (TSUtility.readMenuSelectionPro()) { case '1': lv.modifyMenu(); break; case '2': try { TSUtility.loadSpecialEffects(); } catch (InterruptedException e) { e.printStackTrace(); } nlv.DeveloperManageMainMenu(); break; case '3': tv.developTeamMainMenu(); break; case '4': pv.projectManageMainMenu(); break; case '5': System.out.print("确认是否退出(Y/N)："); if (TSUtility.readConfirmSelection() == 'Y') { System.exit(0); } break; } } } }

主菜单界面如图所示：

 到这里这个项目就完成了，不过界面排版还是不太美观，可以多优化一下。

 完结撒花！
