Comments

Introduction:
Welcome to a tutorial on the use of comments within Java.

What are comments?

When are comments used?

What is the format for a comment?
To submit a comment within Java, there are two ways to do this, the first one is a simple, one line comment which begins with two forward slashes ("//"). The second way allows multiple comment lines in a row which start with an asterix ("*") and is initialised by "/**" and terminated with "*/". Examples below.

Examples:
Here is an example of both types of comment...

1. //System.out.println("1 This line is a comment and so is not ran by Java.");
   
2. System
   
   .out
   
   .println
   
   (
   
   "2 This line is not a comment and so is ran by Java."
   
   )
   
   ;
   
3. 
   
4. /**
   
5. * System.out.println("3 This line is a comment and so is not ran by Java.");
   
6. * System.out.println("3.5 This line is a comment and so is not ran by Java.");
   
7. */
   
8. System
   
   .out
   
   .println
   
   (
   
   "4 This line is not a comment and so is ran by Java."
   
   )
   
   ;
   

2 This line is not a comment and so is ran by Java.
4 This line is not a comment and so is ran by Java.

As you can see, the three lines in the comment types are not ran by Java.
