Quản lý phòng tập GYM - Java basic

by GokiSoft.com - 20:52 08/04/2020 10,749 Lượt Xem

Yêu cầu thiết kế phần mềm quản lý phòng tập GYM

Thực hiện quản lý các chức năng sau

- Quản lý dụng cụ : tên dụng cụ, trọng lượng, chiều dài, rộng, cao, trạng thái (mới, cũ), loại (mua hay mượn)

- Quản lý đồ uống : tên đồ uống, giá tiền

- Quản lý vé: Tên khách hàng, ngày mua, ngày hết hạn

- Tạo Interface đặt tên là : IInputOutput gồm 2 phương thức input() và display()

Yêu cầu tạo các lớp đối tượng trên + tạo hàm tạo hàm hiển thị + biết rằng lớp đối tượng dụng cụ, đồ uống, vé đều kế thừa IInputOutput

Tạo lớp DataMgr gồm danh sách IInputOutput

- Thực hiện nhập vào N đối tượng (ngẫu nhiên dụng cụ. đồ uống, vé) lưu vào mảng trong DataMgr

- Thực hiện hiển thị thông tin phòng gym trên
