How often have you used inheritance mechanisms in your projects?

Inheritance mechanism in Java is used quite often, especially when designing application architecture and implementing object-oriented principles.

I have used inheritance for:

• Creating class hierarchies: when there is a base class with common functionality, and subclasses extend or specify the behavior.

• Polymorphism: to work with objects of different classes through a common interface or base class.

• Code reuse: to avoid duplication and centralize common methods and fields.

However, in modern projects, I try not to abuse inheritance, preferring composition and interfaces to increase flexibility and reduce coupling.

Example:

abstract class Animal {
    abstract void makeSound();
}

class Dog extends Animal {
    @Override
    void makeSound() {
        System.out.println("Woof");
    }
}

class Cat extends Animal {
    @Override
    void makeSound() {
        System.out.println("Meow");
    }
}

// Usage
Animal dog = new Dog();
dog.makeSound(); // Woof

Thus, inheritance is an important tool, but its application depends on specific requirements and the project architecture.
