Java：将图像放置在形状上

我一直在开发一个简单的Java游戏，并且已经成功地使用了形状，但下一个重要步骤是使用图像。我想知道是否有一种方法，我可以简单地将一个图像放置在一个形状上，例如一个矩形，这将使过程更加容易，并且不需要我重新编写大部分代码

以下是我游戏的两个类供参考：

第一个班叫“飞鸟”

我知道这是一个巨大的请求，我想向所有回复的人和这里的精彩社区表示衷心的感谢：-）

好的，不！不要这样使用

static

。呈现单个任务（即“菜单”、“游戏”等等）的设计目的构建视图不会在单个类中完成所有任务。不要使用

keylister

，这只是一场等待发生的火车失事，请改用。那么

图形#drawImage

有什么问题吗？也许你应该看看好的，不！不要这样使用
