What are some examples of the DRY principle in different programming languages?

The DRY (Don't Repeat Yourself) principle emphasizes reducing repetition in code. For example, in Python, you can use functions to encapsulate repeated logic. In Java, you might use inheritance to avoid code duplication. Would you like to see specific code examples?

Yes, please provide a Python example.

Sure! Here's a simple Python example:

def calculate_area(radius):
    return 3.14 * radius ** 2

# Using the function to calculate areas
area1 = calculate_area(5)
area2 = calculate_area(10)

This way, the area calculation logic is defined once and reused.

What about an example in Java?

In Java, you can use inheritance to apply the DRY principle. Here's an example:

class Shape {
    double area;
    void calculateArea() {
        // Common area calculation logic
    }
}

class Circle extends Shape {
    double radius;
    void calculateArea() {
        area = 3.14 * radius * radius;
    }
}

This way, the Shape class contains shared logic, and Circle inherits it.

Can you explain the benefits of using the DRY principle?

Absolutely! The DRY principle helps in reducing code duplication, which leads to easier maintenance, fewer bugs, and improved readability. When you need to make changes, you only have to do it in one place, which saves time and effort.
