Java基础学习：尚硅谷项目三 开发团队调度软件
Java基础学习：尚硅谷项目三 开发团队调度软件
一、软件功能与结构设计
1. 软件功能
该软件实现以下功能：
- 软件启动时，根据给定的数据创建公司部分成员列表（数组）
- 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
- 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
- 开发团队成员包括架构师、设计师和程序员
2. 软件结构设计
二、软件编写流程
1. 创建项目基本组件
- 完成以下工作：
- 创建TeamSchedule项目
- 按照设计要求，创建所有包
- 将项目提供的几个类复制到相应的包中 (view包中：TSUtility.java; service包中：Data.java)
- 按照设计要求，在com.gaorui.team.domain包中，创建Equipment接口及其各实现子类代码
- 按照设计要求，在com.gaorui.team.domain包中，创建Employee类及其各子类代码
- 检验代码的正确性
package com.gaorui.team.service;

1.1 键盘访问的实现
- 项目view包中提供了TSUtility.java类，可用来方便地实现键盘访问。
- 该类提供了以下静态方法：
- public static char readMenuSelection()
用途：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。 - public static void readReturn()
用途：该方法提示并等待，直到用户按回车键后返回。 - public static int readInt()
用途：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。 - public static char readConfirmSelection() ：
用途：从键盘读取‘Y’或’N’，并将其作为方法的返回值。

2. 实现service包中的类
- 按照设计要求编写NameListService类
- 在NameListService类中临时添加一个main方法中，作为单元测试方法。
- 在方法中创建NameListService对象，然后分别用模拟数据调用该对象的各个方法，以测试是否正确
- 注意：测试应细化到包含了所有非正常的情况，以确保方法完全正确
- 重复1-3步，完成TeamService类的开发
