java项目实战——Java打飞机小游戏（附完整源码）.docx

1、摘要： 写在前面 技术源于分享，所以今天抽空把自己之前用 java 做过的小游戏整理贴出来给大家参考学习。java 确实不适合写桌面应用，这里只是通过这个游戏让大家理解 oop 面向对象编程的过程，纯属娱乐。代码写的很简单，也很容易理解，并且注释写的很清楚了，还有问题，自己私下去补课学习。写在前面技术源于分享，所以今天抽空把自己之前用 java 做过的小游戏整理贴出来给大家参考学习。java 确实不适合写桌面应用，这里只是通过这个游戏让大家理解oop 面向对象编程的过程，纯属娱乐。代码写的很简单，也很容易理解，并且注释写的很清楚了，还有问题，自己私下去补课学习。完整代码敌飞机import ja
