Java Comments

Comments in any programming language are ignored by the compiler or the interpreter. A comment is a part of the coding file that the programmer does not want to execute, rather the programmer uses it to either explain a block of code or to avoid the execution of a specific part of code while testing.

There are two types of coments:

• Single-line comment
• Multi-line comment

 

A. Single Line Comments:

To write a single-line comment just add a ‘//’ at the start of the line.

Example:

package syntax1;
public class Details {
    public static void main(String[] args) {
        //This is a single line comment
        System.out.println("Hello World!!!");
      }
}

Output:

Hello World!!!

 

B. Multi Line Comments:

To write a multi-line comment just add a ‘/*…….*/’ at the start of the line.

Example:

package syntax1;

public class Details {
    public static void main(String[] args) {
        /*This
         * is 
         * a
         * Multiline 
         * Comment
         */
        System.out.println("Hello World!!!");
      }
}

 

Output:

Hello World!!!
