Does using Interfaces instead of abstract classes affect their performance?

modularity can be increased if? 1. use global variables 2. lower cohesion and increase coupling 3. lower coupling and increase cohesion 4. keep each method size less than 30 lines of code

Class A is the parent class, while classes B and C are the subclasses of A. Both B and C contain several features and techniques that are equivalent to one another; nevertheless, the implementations of some of their methods are quite different between the two. Explain what kind of class A will be using logic; is it going to be a concrete class, an abstract class, or an interface?

when an object of a subclass is instantiated, a superclass constructor Is called simplicity or explicitly true or false?

Question Kh  Write the definition of classes and interfaces in the given diagram using following details: a) Interface shape has a method draw(). b) Override the method draw() in all subclasses. c) Define a non-abstract method fillColor() in Circle class. Full explain this question very fast solution sent me step by step Don't ignore any part all part work u

The main differences between method overloading and method overriding should be clarified.

Subclasses of abstract classes must implement the parent class's abstract methods. You think?

It is necessary for a subclass of an abstract class to implement all of the abstract methods that are defined for the parent class. Is there a mistake or is it accurate?
