Java interface methods never used

由 半城伤御伤魂 提交于 2021-02-18 18:14:12
问题 So, I started using interfaces in Java a while ago. I have already created one, and I have a class , that implements that interface. So this is the interface itself: And this is the class that implements the Actor interface : But, as you can see in the first picture, no methods are used, ecxept for create() . The most strange thing is that everything works absolutely fine! Only these underlined words freak me out a bit) 回答1: Your methods are never actually used. This is IntelliJ's way of
