QUESTION
I came from Java OOP background and understand interfaces.
Currently working on a simple budgeting app (https://github.com/compound-developers/compound-supply-examples) that takes ETH or Stablecoin and put in in Compound and earn interest.
My confusion is how Solidity Interfaces are used. I came from OOP (Java) background and very familiar with interfaces.

without any implementation.
