Java Tutorial/Language/Comments

Comments in general

It is good practice to write comments explaining your code.

There are two types of comments in Java, both with syntax similar to comments in C and C++.

1. Traditional comments: Enclose a traditional comment in /* and */.
2. End-of-line comments: Use double slashes (//) which causes the rest of the line ignored by the compiler.

Traditional comments do not nest, which means

/*
  /* comment 1 */
  comment 2 */

Multiple lines of comment

/*   multiple lines of comment
another line
 */ 
public class MainClass{
  public static void main(String[] arg){
     
  }
}

Program Comments: Single line of comment

//   Single line of comment
public class MainClass{
  public static void main(String[] arg){
     
  }
}
