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》。
通过该项目,熟悉Java面向对象的特性,可以进一步掌握编程和调试的技巧。
项目的系统功能结构如下图所示:
系统流程图如下图所示:
软件启动时,首先进入登录界面进行注册、登录功能
登陆成功后,进入主菜单
可以修改注册时的用户名和密码
对开发人员的信息进行增删改查操作
人员信息添加完成后,可以根据现有的成员,创建开发团队
创建开发团队过程中,包括基于已有的人员信息添加团队的成员,或删除团队中的某位成员,还可以列出当前已在团队中的成员的列表
团队创建完成后就可以进入项目模块,添加项目后,分配给开发团队进行开发
该软件由view、service和domain三个模块组成
view模块:主控模块,负责各种功能的菜单显示以及处理用户的操作
service模块:该模块为实体类的管理模块,处理功能的逻辑上的业务
domain模块:管理实体类对象
Employee(雇员)、Programmer(程序员)、Designer(设计师)、Architect(架构师)、 PC(台式电脑)、NoteBook(笔记本电脑)、Printer(打印机)、project(项目)
还有一个接口(interface):Equipment(电子设备)
public interface Equipment {
String getDescription();
}
实体类中的继承关系为:
Programmer extends Employee
Designer extends Programmer
Architect extends Designer
其中程序员(Programmer)及其子类均会领取某种电子设备(Equipment)
所以PC(台式电脑)、NoteBook(笔记本电脑)、Printer(打印机)都实现了Equipment(电子设备)这个接口
说明:
model:表示机器型号
display:表示显示器名称
typ:表示机器的型号
根据各个类中的属性提供get/set方法以及重载构造器
实现类实现接口方法,返回各自的属性信息
说明:
memberId: 用来记录成员加入开发团队后在团队中的ID
Status:是项目中人员的状态,先赋值为true,当添加到团队时为false
equipment :表示该成员领用的设备
bonus :表示奖金
stock :表示公司奖励的股票数量
可根据需要为类提供各属性的get/set方法以及重载构造器
项目的主体架构如下:
说明:
getAllEmployees ()方法:获取当前所有员工。
返回:包含所有员工集合
getEmployee(id : int)方法:获取指定ID的员工对象。
参数:指定员工的ID
返回:指定员工对象
异常:找不到指定的员工
在service子包下提供自定义异常类:TeamException
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)
public class NameListService {
//用来装员工的数据集合
private ArrayList employees = new ArrayList<>();
//添加员工的id
private int count = 1;
//使用代码块初始化默认值
{
employees.add(new Employee(count, "张译文 ", 22, 3000));
employees.add(new Architect(++count, "李婉怡", 32, 18000, new NoteBook("联想T4", 6000), 60000, 5000));
employees.add(new Programmer(++count, "李彦宏", 23, 7000, new PC("戴尔", "NEC 17寸")));
employees.add(new Programmer(++count, "王刘", 24, 7300, new PC("戴尔", "三星 17寸")));
employees.add(new Designer(++count, "孟雨 ", 50, 10000, new Printer("激光", "佳能2900"), 5000));
employees.add(new Programmer(++count, "任志强", 30, 16800, new PC("华硕", "三星 17寸")));
employees.add(new Designer(++count, "柳传志", 45, 35500, new PC("华硕", "三星 17寸"), 8000));
employees.add(new Architect(++count, "杨元庆", 35, 6500, new Printer("针式", "爱普生20k"), 15500, 1200));
employees.add(new Designer(++count, "史玉柱", 27, 7800, new NoteBook("惠普m6", 5800), 1500));
employees.add(new Programmer(++count, "丁磊 ", 26, 6600, new PC("戴尔", "NEC17寸")));
employees.add(new Programmer(++count, "张朝阳 ", 35, 7100, new PC("华硕", "三星 17寸")));
employees.add(new Designer(++count, "杨致远", 38, 9600, new NoteBook("惠普m6", 5800), 3000));

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。

功能:关于开发团队成员的管理:添加、删除等
说明:
counter为静态变量,用来为开发团队新增成员自动生成团队中的唯一ID,即memberId。(提示:应使用增1的方式)
MAX_MEMBER:表示开发团队最大成员数
team数组:用来保存当前团队中的各成员对象
total:记录团队成员的实际人数
getTeam()方法:返回当前团队的所有对象
返回:包含所有成员对象的数组,数组大小与成员人数一致
addMember(e: Employee)方法:向团队中添加成员
参数:待添加成员的对象
异常:添加失败, TeamException中包含了失败原因
removeMember(memberId: int)方法:从团队中删除成员
参数:待删除成员的memberId
异常:找不到指定memberId的员工,删除失败

在运行时输入错误信息抛出来的异常带有其他详细信息,观察代码后发现没有将catch里的printStackTrace()改为getMessage()。因为printStackTrace()是将捕获到的异常信息完整的输入在控制台上,而getMessage()是返回此 throwable 的详细消息字符串。
在给项目分配团队时,会给已分配团队的项目再次分配,改进的方法是在为项目分配团队是进行判断,遍历项目查看是否已近被分配团队了,如果没有,就为它分配;如果已分配就直接跳出,不在进入分配;
代码如下:
boolean f = false;
for (Project p : projects) {
//判断项目的状态
//1.1项目状态为false未分配,进入if判断,将true赋值给f
//2.1项目状态为true已分配,不进入if判断,此时f的值为false
if (!p.isStatus()) {
f = true;
break;
}
//1.2现在f的值为true,不进入if判断,进入增强for循环为项目分配团队
//2.2f为false,进入if,执行return,结束方法,不进入增强for循环
if (!f) {
System.out.println("没有项目未被分配");
return;
}
}
for (Programmer[] programmers : manyTeam) {
projectSer.dealingPro(programmers);
}
在开发过程中还经常遇到的一些小问题,比如:空指针、索引越界等等,还需要多多的积累。
