Equipment接口
包括：Equipment接口
PC、noteBook、Printer三个实现类
该接口实现类的创建：(快捷方法)
- implements接口，添加私有属性
- alt+shift+s->generate Setters and Getters 全选 创建属性调用方法
- alt+shift+s->generate constructor using Fields 分别创建带参和不带参的构造函数
- 实现接口的抽象方法，可利用报错处自动创建并修改
Equipment.java

PC.java

Employee类及其子类
完成employee相关类的创建
- employee 员工类，父类，包括id,name,age,salary四个基本属性
- programmer 程序员类，继承自employee类，从程序员开始可以被添加到团队中，拥有memberId、staus、equipment基本属性
- designer 设计师类，继承自employee类，从设计师开始有奖金，拥有bonus基本属性
- Architect 架构师类，继承自设计师类，从架构师开始有奖金，拥有block基本属性
- status 状态类，是一个枚举类，表示员工状态，包括BUSY、FREE、VOCATION三种状态
