I am trying to learn basic object oriented programming in Java. I was curious to know what the beginning of the word interface is, if there is any documentary description. In addition, I tried to understand what this means by thinking of a general concept like
The point at which two systems, objects, organizations, etc. meet and interact.
I got this definition from a Google search. What are the two systems / entities that interact? Or maybe my analogy is used inappropriately? So far, I see this as a skeleton for defining methods and property loops.

"Two systems" (you requested) is code that implements the interface and code that references it.
