Which of the following contributes to improving code readability in Java?

Consistent use of indentation and whitespace significantly enhances code readability in Java by providing a clear visual structure. This practice allows developers to easily identify code blocks, understand the hierarchy of the code, and follow the logical flow of the program. Proper indentation helps in distinguishing between different levels of loops, conditionals, and method definitions, which makes it easier for others (or even the original author at a later time) to read and comprehend the code quickly.

Well-structured whitespace can also break up long lines and delineate different sections of code, promoting a more organized appearance. In collaborative environments, clear readability is essential for maintenance and modification of code, as multiple programmers may need to interact with each other’s code. Therefore, adherence to a consistent indentation style and strategic use of whitespace are key practices in coding standards that contribute to the overall quality and readability of the code.
