Static methods are class level methods. That means that you don't have to wait for an instance of the class to be created in order to use it. It also means that the system can resolve the method at compile time, preventing it from participating in
polymorphism.
Abstract methods are those that have no implementation (no actual code in them). The whole purpose of them is so that we can talk about methods ahead of time and wait for runtime to resolve the implementation (in some sub-class).
So these have basic different needs and lifecycles and are incompatible.
