💛 Overriding in Java with Test Automation 💚

Hey everyone! Let's dive into some Java fundamentals today, especially for those who are venturing into automation testing.

Here's a quick breakdown of key concepts and their relevance in the world of automation.

🔺 1️⃣ Overriding in Java:

Overriding is a concept in Java that allows a subclass to provide a specific implementation of a method that is already defined in its superclass. It enables polymorphism, where the same method name can behave differently based on the object it's called on.

🔺 2️⃣ Main Points to Remember about Overriding:

👉🏻 Method signature:

The overriding method must have the same method signature (name, parameters, return type) as the overridden method in the superclass.

👉🏻 Access modifier:

The overriding method cannot have a more restrictive access modifier than the overridden method. It can have the same or wider access modifier.

👉🏻 Return type:

The return type of the overriding method must be the same as, or a subtype of, the return type of the overridden method.

🔺 3️⃣ Example Code of Overriding with Selenium:

// Superclass

class WebDriver {

public void get(String url) {

System.out.println("Opening URL: " + url);

}

}

// Subclass

class ChromeDriver extends WebDriver {

@Override

public void get(String url) {

System.out.println("Opening URL in Chrome: " + url);

}

}

// Usage

public class Main {

public static void main(String[] args) {

WebDriver driver = new ChromeDriver();

driver.get("https://www.example.com");

}

}

In this example, the get method is overridden in the ChromeDriver subclass to provide a specific implementation for opening URLs in Chrome.

🔺 4️⃣ Overriding vs. Overloading:

Overriding occurs in inheritance, where a subclass provides a specific implementation of a method that is already defined in its superclass.

Overloading involves defining multiple methods in the same class with the same name but different parameters.

Understanding these concepts is crucial for building robust automation frameworks with Selenium, where customization and extensibility are key.
