Java Comments

Java comments are non-executable statements used for documentation and explanation purposes. Here's a brief overview:

Single-Line Comments:

• Single-line comments start with //.
• They extend from the // marker to the end of the line and are ignored by the compiler.

Multi-Line Comments:

• Multi-line comments are enclosed between /* and */.
• They can span multiple lines and are ignored by the compiler.

Javadoc Comments:

• Javadoc comments are used to generate documentation for Java code.
• They start with /** and end with */.
• Javadoc comments can include special tags like @param, @return, and @throws to provide additional information about methods and classes.

Example

// This is a single-line comment

/*
 * This is a multi-line comment.
 * It can span multiple lines.
 */

/**
 * This is a Javadoc comment for the HelloWorld class.
 * It provides information about the class.
 */
public class HelloWorld {
    /**
     * This is a Javadoc comment for the main method.
     * It describes the purpose of the main method.
     * @param args Command-line arguments
     */
    public static void main(String[] args) {
        System.out.println("Hello, World!"); // This is an inline comment
    }
}

Summary

Java supports single-line comments (//), multi-line comments (/* */), and Javadoc comments (/** */). Comments are essential for improving code readability, providing explanations, and generating documentation for Java code.
