They are used to create a base implementation or contract for the actual implementation classes.Car.java: Base interface or abstract class package com.journaldev.oops.abstraction; public interface Car { void turnOnCar(); void tur...
This is possible in LESS (LESS being the question mark), evidenced by the existence of frameworks such asLESS Elements. People talk about LESS reducing boilerplate and repetition. Or about hiding browser-specific CSS properties. But that is not the essence of the matter. What all of that tal...
