What's the difference between libraries and interfaces?
For example, in the line:
import java.util.Scanner;
Would util be the interface and Scanner of the class? Or would util be the library and Scanner would still be the class?
In the case of methods with @Override it only makes sense when working with interfaces? In case of inheritance I do not know if you have so much reason.
The terms are completely wrong and mixed.
There is a relationship between class and interface.
Library is a generic term that is not used in the code itself. What you are probably talking about are packages .
So in the example the java.util is the package. And Scanner is the class.
You are not currently using interface there. More information . When to use .
