Can we static methods/class can implement Interface

No, Method of interface cannot be implemented as a static methods because Methods specified on an interface should be there to specify the contract for interacting with an object. Static methods do not allow you to interact with an object - if you find yourself in the position where your implementation could be made static, you may need to ask yourself if that method really belongs in the interface.

The core design principle of static methods, the principle that gives them their name...[is] can always be determined exactly, at compile time, what method will be called. That is, the method can be resolved solely by static analysis of the code

Interfaces specify behavior of an object.

Static methods do not specify a behavior of an object, but behavior that affects an object in some way.
