我创建了一个屏幕保护程序，可以在屏幕上来回切换。我试图将原始代码放入OOP中(我很擅长OOP(，这样我就可以有多个版本的OOP。相反，我看到了一个以异常快的速度旅行的例子。
如何使instance1、instance2和instance3分离而不是合并为一？
注意事项：在类screenSavers中，C代表构造函数参数，以区别于顶部的原始变量。CS代表特定类，以避免与顶部的原始变量混淆。(是的，这很令人困惑。我不知道我为什么这么做(

现在，您可以使用完全相同的属性初始化所有3个实例。它们只是"；组合的"；因为你做的都一样。您应该确定您希望它们之间有什么不同，并传递不同的属性。
其他注意事项：
-
为什么screenSavers有main((函数？删除
-
请将其重命名为ScreenSaver。
-
不要区分使用C和CS。只要给它们起同样的名字。但是使用
this关键字来区分类vars。示例：this.frameW = frameW; -
对if语句使用适当的缩进。
顺便说一句，几天后找到了它，我正在寻找this关键字
