not quite right.

On the one hand, a lot of patterns have similar code. On the other hand, their intentions are entire different, the invariants and variants are hidden under the code.

In the strategy patten, we want to switch strategies, depending on different values of some fieldMoon. The place to switch is the tricky part, i.e., where do you want to put the switching code, e.g., in the caller's constructor, or in an if-else block, or on a method signature.

工厂模式 种类 可多了,共同点 是 得返回 产品,呵呵,策略 可不一定,是void 也可以,只是根据条件 不同,处理策略不同, 如果说 策略 与 状态 有点象,我同意,呵呵
