Comments in Java

In this tutorial, you’ll learn how to add Java Comments which is the basic and start of your Java Programming.

The Java Comments are used to comment is a programmer-readable explanation or annotation in the source code of a computer program

The characters in the /* */ are comments:

/*
* The HelloWorldApp class implements an application that
* simply displays "Hello World!" to the standard output.
*/
class HelloWorldApp
{
public static void main(String[] args)
{
System.out.println("Hello World!"); //Display the string.
}
}

The Java language supports three kinds of comments:

/* text */

The compiler ignores everything from /* to */.

/** documentation **/

This indicates a documentation comment (doc comment, for short). The compiler ignores this kind of comment, just like it ignores comments that use /* and */. The JDK Javadoc tool uses doc comments when preparing automatically generated documentation.

// text

The compiler ignores everything from // to the end of the line.

Ask your questions and clarify your/others doubts on Java Comments by commenting. Java Documentation.
