Writing Comments in Java

Objective :

  • How to write comments in Java?
  • How to write single line comment in Java?
  • How to write multi line comment in Java?
  • How to write documentation comment in Java?
  • What are the types of comments in Java?

Writing Comments in Java :

  • Comments are the statements which are never executed (i.e. non-executable statements).
  • Comments are often used to add notes between source code so that it becomes easy to understand & explain the function or operation of the corresponding part of source code.
  • Java Compiler doesn’t read comments; comments are simply ignored during compilation.
  • There are 3 types of comments available in Java as follows;
  1. Single Line Comment
  2. Multi Line Comment
  3. Documentation Comment

Single Line Comment :

This comment is used whenever we need to write anything in single line.

Syntax : 

//<write comment here>

Example :

[sourcecode language=”java”]
//This is Single Line Comment.

Multi Line Comment :

This type of comments are used whenever we want to write detailed notes (i.e. more than one line or in multiple lines)related to source code.

Syntax :


<write comment here>


Example :  

[sourcecode language=”java”]

Documentation Comment :

  • The documentation comment is used commonly to produce the javadoc for the respective program.
  • The javadoc is generally HTML, if used in project it is a set of multiple HTML files describing each java program in the corresponding project.
  • In the documentation comment we can add different notations such as author of the project or program, version, parameters required, information on results in return if any, etc.
  • To add these notations, we have ‘@’ operator.  We just need to write the required notation along with the ‘@’ operator.
  • Some javadoc tags are;
    1. @author – To describe the author of the project.
    2. @version – To describe the version of the project.
    3. @param – To explain the parameters required to perform respective operation.
    4. @return – To explain the return type of the project.

Syntax :


*<write comment/description here>

*@author <write author name>

*@version <write version here>

*@param <write parameter here>

*@return <write return type here>


Example :  

[sourcecode language=”java”]
* This is Documentation Comment.
* @author Atul Palandurkar
* @version 1.0.0
