Comments In Java

What are Java comments?

Comments are used to explain the code and make it more readable. They are not executed by the compiler. There are two types of comments in Java: single-line comments and multi-line comments.

Single-line comments :-

Single-line comments start with two forward slashes (//) and continue to the end of the line. 

For example :-

// This is a single-line comment

Multi-line comments :-

Multi-line comments start with a forward slash and asterisks (/*) and end with asterisks and a forward slash (*/). 

For example :-

/*

This is a multi-line comment

that can span multiple lines

*/

Example :-

//Hare I use Single line comments and Multi line comments.

class Scomment

{

    public static void main(String args[])

    {

         /* In this program I use Single line comments 

                       and Multi line comments  */

         System.out.println(“Multi line comments below”);

    }

}

Note :- I use  Comments that is not read as the code but it is read as comments in the program by java compiler

• To make your code more readable: Comments can help you to explain what your code is doing, which can make it easier for you to understand and maintain your code in the future.
• To document your code: Comments can be used to document your code, which can help other developers to understand your code.
• To prevent errors: Comments can be used to prevent errors by explaining what your code is supposed to do. For example, you can use a comment to explain the purpose of a complex expression or to explain the logic of a conditional statement.
