OOP in Different Programming Languages 🌍

Why Compare OOP Across Languages? 🤔

OOP principles are universal, but their implementation varies between languages. Understanding these differences helps in choosing the right language for specific projects and enhances cross-language development skills.

---

1️⃣ OOP in Java ☕

✅ Fully object-oriented with strong encapsulation.
✅ Supports interfaces and abstract classes.
✅ Uses JVM for cross-platform compatibility.
✅ Single inheritance, but allows multiple inheritance via interfaces.

Example 📌:

class Animal {
    void makeSound() {
        System.out.println("Animal makes a sound");
    }
}
class Dog extends Animal {
    void makeSound() {
        System.out.println("Bark");
    }
}

---

2️⃣ OOP in Python 🐍

✅ Dynamic typing (no need to declare variable types).
✅ Supports multiple inheritance natively.
✅ Uses duck typing (an object’s behavior determines its validity, not its class).

Example 📌:

class Animal:
    def make_sound(self):
        print("Animal makes a sound")
class Dog(Animal):
    def make_sound(self):
        print("Bark")

3️⃣ OOP in C++ 🔵

✅ Supports both procedural and object-oriented programming.
✅ Allows multiple inheritance and operator overloading.
✅ Requires manual memory management (pointers).

Example 📌:

class Animal {
public:
    virtual void makeSound() {
        cout << "Animal makes a sound";
    }
};
class Dog : public Animal {
public:
    void makeSound() override {
        cout << "Bark";
    }
};

---

4️⃣ OOP in JavaScript 🌐

✅ Prototype-based OOP instead of class-based.
✅ Introduced class syntax in ES6 for better readability.
✅ Uses closures and prototypal inheritance.

Example 📌:

class Animal {
    makeSound() {
        console.log("Animal makes a sound");
    }
}
class Dog extends Animal {
    makeSound() {
        console.log("Bark");
    }
}

---

5️⃣ OOP in C# ⚡

✅ Fully object-oriented with strong type safety.
✅ Supports interfaces, properties, and events.
✅ Has garbage collection for memory management.

Example 📌:

class Animal {
    public virtual void MakeSound() {
        Console.WriteLine("Animal makes a sound");
    }
}
class Dog : Animal {
    public override void MakeSound() {
        Console.WriteLine("Bark");
    }
}

Conclusion 🎯

Each language implements OOP differently! Java and C# enforce strict OOP, while Python and JavaScript offer more flexibility. C++ gives low-level control but requires careful memory management. Choose the language based on your project needs! 🚀
