Java Comments

Java comments

Created By: chatGPT

Comments in Java are crucial for enhancing the readability and maintainability of your code. They are essentially notes that developers add to explain what certain parts of their code do or to leave reminders. Java supports three types of comments: single-line, multi-line, and documentation comments.

// This is a single-line comment
int a = 5; // Assign 5 to variable a

A single-line comment begins with two forward slashes (//). Everything following those slashes on that line will be ignored by the compiler. This is useful for brief explanations or notes.

// Calculate the area of a rectangle
int width = 10;
int height = 5;
int area = width * height;

Multi-line comments start with /* and end with */. They are useful for longer explanations spanning several lines. This type of comment can be used anywhere in your code.

/* This is a multi-line comment
   that can span multiple lines.
   Useful for detailed descriptions. */
int b = 10;

Documentation comments are a special type of multi-line comment that begin with /** and end with */. They are used to generate documentation for classes, methods, and fields. Tools like Javadoc can read these comments to create detailed API documentation.

/**
 * This method calculates the square of a number.
 * @param number the number to be squared
 * @return the square of the number
 */
public int square(int number) {
    return number * number;
}

Overall, using comments effectively can greatly improve your code, making it easier for others (and yourself) to understand what has been implemented. Remember, comments should clarify your code, not restate it. Use them wisely to maintain clean and readable code.
