Java Comments

There are three types of comments in Java

1. Single Line comment

To comment on a single line of code, you can use a double forward slash “//” followed by your message. This syntax is commonly used for coding.

Java




/*package whatever //do not write package name here */
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
        System.out.println("GFG!");
        // System.out.println("Thi line is not executed");
    }
}


Output

GFG!

2. Multi-line comment

If you need to comment on multiple lines of code, you can utilize the syntax of a double forward slash “/*”. Simply enter your message between the two symbols, and complete the comment with “*/”. This is a widely used syntax in coding.

Java




/*package whatever //do not write package name here */
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
        System.out.println("GFG!");
        /* System.out.println("This line is Ignored ny
        comiler"); System.out.prinln("Including this");
        */
    }
}


Output

GFG!

3. JavaDoc Type Comment

When working on a project or software package, it is often helpful to use this method as it can assist in creating a documentation page for reference. This page can provide information on available methods, their parameters, and more, making it a useful tool for learning about the project.

Syntax:

/** Comment starts 
*This is
*sample comment */
