Equipment接口
包括：Equipment接口
PC、noteBook、Printer三個實現類
該接口實現類的創建：(快捷方法)
- implements接口，添加私有屬性
- alt+shift+s->generate Setters and Getters 全選 創建屬性調用方法
- alt+shift+s->generate constructor using Fields 分別創建帶參和不帶參的構造函數
- 實現接口的抽象方法，可利用報錯處自動創建並修改
Equipment.java

Employee類及其子類
完成employee相關類的創建
- employee 員工類，父類，包括id,name,age,salary四個基本屬性
- programmer 程序員類，繼承自employee類，從程序員開始可以被添加到團隊中，擁有memberId、staus、equipment基本屬性
- designer 設計師類，繼承自employee類，從設計師開始有獎金，擁有bonus基本屬性
- Architect 架構師類，繼承自設計師類，從架構師開始有獎金，擁有block基本屬性
- status 狀態類，是一個枚舉類，表示員工狀態，包括BUSY、FREE、VOCATION三種狀態
