本篇内容介绍了“Java如何实现潜艇小游戏”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
首先是主方法里定义的窗口（这些都是固定的格式，不会的也没什么事，直接Ctrl+c+v就行，基本上看一下数据都能看的懂）
写一个超类，超类里需要有潜艇，深水炸弹，水雷和战舰的宽，高，以及出场时的x，y坐标，和移动速度。所有对象的图片，所有对象的移动方法，以及碰撞
然后再写派生类，根据击败一个水雷潜艇，战舰会获得一条命，击败其他潜艇，战舰会获得分数，所以，需要定义两个接口，一个是用来加命，另一个用来加分
完整代码如下（图片什么的可以自己去找，只需要改一下Image类和各个对象的宽高就可以）
