本系统旨在开发一款集单机功能与网络功能于一体的小游戏——坦克大战，该游戏能让用户自主选择游戏模式。其中，单机模式为用户与电脑的对战，网络联机模式则为玩家通过网络连接其他玩家联合对抗电脑，共同完成整局游戏。本设计运用Java语言编写，主要使用Java中的Swing、GUI、Socket、线程、面向对象设计等技术实现，模拟实现了坦克的移动与射击，子弹的发射与爆炸等功能模块。其中，不同的游戏模式使用不同的游戏规则，使得整个游戏的趣味性增强，用户体验性增强，整个系统具有良好的娱乐性与互动性。-This system aims to develop a set of stand-alone functions and network functions in one game- Battle City, the game allows the user to choose the game mode. Among them, the stand-alone mode for the user and computer gaming, network players online mode compared to other players via a network connection joint fight against the computer together to complete the entire game round. The use of design written in Java, the main use of Java in the Swing, GUI, Socket, threaded, object-oriented design, technology, simulation of the movement of tanks and shooting, bullets and explosions emitting functional modules. Among them, the different game modes with different rules of the game, making the game interesting enhancements, enhanced user experience, the whole system has good entertainment and interactivity
