"自动售货机软件设计：Java语言实现硬币识别、自动售货、找零功能"

自动售货机" has rapidly developed. The automatic vending machine has attracted a large number of customers, who can use it to purchase drinks, snacks, and other goods. In developed countries, automatic vending machines have become an inseparable part of the retail industry, attracting numerous customers with its avant-garde consumption methods. Moreover, in response to global warming, the development of new types of automatic vending machines is dedicated to energy saving. This undergraduate thesis focuses on the development of automation, energy saving, and computer software. The software designed in this thesis can be more conveniently applied in automatic vending machines. The study systematically explores the design of automatic vending machines using the Java language, implementing features such as coin recognition, coin accumulation, automatic vending, and automatic change-making. The program code of this software is flexible and extensible, allowing for reuse and minimal impact on existing code when implementing new features in the entire system.
