Kotlin and Android Practice Test 2025 – Complete Exam Prep Guide

In Kotlin, comments are used to annotate the code and can enhance its readability. There are two primary ways to create comments: single-line comments and multi-line (block) comments.

When creating a single-line comment, you can start a line with `//`. Everything following `//` on that line will be treated as a comment. This is a straightforward method for adding comments to code.

For multi-line comments, you start with `/*` and end with `*/`. This allows you to encapsulate several lines of code or text as a comment. However, using `/*` to initiate a comment that is intended to cover just one line is somewhat unconventional, as its primary use is meant for longer, block structures.

The provided answer highlights that using `/*` to start a comment that is just one line long is not standard practice in Kotlin. While it technically functions to create a comment, the intention behind the way comments are typically written in Kotlin prefers the single-line format for brevity and clarity when only one line is necessary. Thus, the specific phrasing of that answer indicates a lack of clarity regarding the proper context for beginning comments.
