Which of the following describes a clean and effective use of whitespace in Java?

The choice that describes a clean and effective use of whitespace in Java is the addition of line breaks after method declarations for clarity. Utilizing whitespace strategically enhances the readability of the code, making it easier for developers to understand the structure and flow.

When a programmer places line breaks after method declarations, it visually separates the method from the subsequent code, allowing other developers (or even the original author returning to the code later) to quickly identify method boundaries. This practice reduces cognitive load, aiding in navigation through the code, and makes it clearer where one method ends and the next begins.

Maintaining thoughtful use of whitespace, such as line breaks, contributes to a more professional and maintainable coding style, enhancing collaboration in team environments and overall code quality.
