我正在努力完成我的计算机科学课程的最终项目。我们在课堂上使用java，我对它的控件/概念非常熟悉。我已经制作了一个版本的游戏洪水 - 然而，分配的要求是OOP，继承/接口和多态。我已经有其他组件和我的游戏工作，但我不知道如何包括那些。此外，有时它会出现故障并且不会切换应该切换的随机方块，但我无法找到任何问题

答案 0 :(得分：0)
除非您必须编写自己的接口，否则您已经实现了ActionListener接口。因此，要添加多态性和继承，您需要拆分FloodIt类。转到模型，视图和控制器模式。在您这样做之后，将更容易实现所需的方法。你可以做一个抽象方形超类，然后做它的不同颜色的子类。之后，您可以将Squares放在2D数组中，然后根据调用的有色方块调用方法。通过这种方式，您实现了继承和多态，因为这些方法是在运行时选择的。
