We can use this keyword inside a constructor to call another constructor within the same class. This is called __________________.

This keyword is called "this". In object-oriented programming, specifically in languages such as Java, C++, and C#, the this keyword is used within a constructor to refer to the current instance of the class. When this is used to call another constructor in the same class, it's known as constructor chaining. This allows for code reusability and cleaner code.

For example, consider a class Car where one constructor initializes the make and model, while another constructor initializes the make, model, and year. Using this allows the second constructor to call the first, avoiding code duplication and keeping the code maintainable.

Constructor chaining via this can enhance readability and reduce redundancy in your code, making it easier to extend and modify in the future.
