Core Concepts of OOP​

1. Encapsulation​

2. Inheritance​

3. Polymorphism​

4. Abstraction​

Example in C++​

#include <iostream>
#include <string>
using namespace std;


// Bank Account Class
class BankAccount {
private:
    string ownerName;
    double balance;


public:
    BankAccount(string name, double initialBalance) {
        ownerName = name;
        balance = initialBalance;
    }


    void deposit(double amount) {
        balance += amount;
    }


    void withdraw(double amount) {
        if (balance >= amount) {
            balance -= amount;
        } else {
            cout << "Insufficient funds!" << endl;
        }
    }


    void display() {
        cout << "Account Owner: " << ownerName << endl;
        cout << "Balance: $" << balance << endl;
    }
};


int main() {
    // Create Bank Account objects
    BankAccount acc1("John Doe", 1000);
    BankAccount acc2("Jane Smith", 500);


    // Perform operations
    acc1.display();
    acc1.deposit(500);
    acc1.withdraw(200);
    acc1.display();


    acc2.display();
    acc2.withdraw(1000); // Insufficient funds
    acc2.display();


    return 0;
}

Example in Java​

// BankAccount Class
class BankAccount {
    private String ownerName;
    private double balance;


    public BankAccount(String name, double initialBalance) {
        ownerName = name;
        balance = initialBalance;
    }


    public void deposit(double amount) {
        balance += amount;
    }


    public void withdraw(double amount) {
        if (balance >= amount) {
            balance -= amount;
        } else {
            System.out.println("Insufficient funds!");
        }
    }


    public void display() {
        System.out.println("Account Owner: " + ownerName);
        System.out.println("Balance: $" + balance);
    }
}


public class Main {
    public static void main(String[] args) {
        // Create Bank Account objects
        BankAccount acc1 = new BankAccount("John Doe", 1000);
        BankAccount acc2 = new BankAccount("Jane Smith", 500);


        // Perform operations
        acc1.display();
        acc1.deposit(500);
        acc1.withdraw(200);
        acc1.display();


        acc2.display();
        acc2.withdraw(1000); // Insufficient funds
        acc2.display();
    }
}

Background​

C++​

Speed & Performance​

• C++ is renowned for its speed and performance, making it ideal for system programming, game development, and other performance-critical applications.
• It provides direct access to memory, allowing for efficient use of system resources.

Control & Low-Level Operations​

• Offers more control over hardware, memory management, and pointers.
• Well-suited for developing operating systems, device drivers, and embedded systems.

Legacy Codebase​

• Many legacy applications and systems are written in C++, ensuring its relevance for years to come.
• Used extensively in industries where performance is critical, such as finance and real-time systems.

Java​

Platform Independence​

• Java's "write once, run anywhere" principle allows for platform-independent code.
• Applications can run on any device with a Java Virtual Machine (JVM), enhancing its portability.

Object-Oriented​

• Java is a pure object-oriented language, making it great for large-scale, modular applications.
• Encapsulation, inheritance, and polymorphism are key features, promoting code reusability and maintainability.

Robust Libraries & Frameworks​

• Widely used in web development (e.g., backend services), Android app development, and enterprise software.

When to Use C++ vs Java​

Use C++ When:​

• Performance is critical, such as in game development, real-time systems, or high-frequency trading.
• Low-level system programming or working with hardware is necessary.
• You need control over memory management and direct access to system resources.

Use Java When:​

• Platform independence is a priority, allowing your application to run on various devices without modification.
• Developing large-scale, enterprise applications where maintainability and scalability are crucial.
• You require a rich ecosystem of libraries and frameworks for rapid development.
