Learn kotlin Comments


Sure! Comments in Kotlin are used to add explanations or notes within your code that are ignored by the compiler. They help make your code more readable and understandable for yourself and others who might be working with your code. Here's how you can use comments in Kotlin:

Single Line Comments

You can use single line comments by starting a line with //. Anything following // on that line will be treated as a comment.

Example

// This is a single line comment
val x = 5 // This is also a single line comment

Multi-line Comments

You can use multi-line comments by enclosing your comment within /* and */. Everything between these symbols will be considered a comment.

Example

/*
This is a multi-line comment.
It can span multiple lines.
*/
val y = 10

Documentation Comments

Documentation comments are similar to multi-line comments but are specifically used for generating documentation for your code. They are enclosed within /** and */ and often used to describe classes, functions, and parameters.

Example

/**
* This function adds two numbers and returns the result.
* @param a The first number to be added.
* @param b The second number to be added.
* @return The sum of a and b.
*/
fun addNumbers(a: Int, b: Int): Int {
return a + b
}

Conclusion

Comments are essential for documenting your code and making it easier to understand. By using single-line comments, multi-line comments, and documentation comments appropriately, you can improve the readability and maintainability of your Kotlin code.
