There are two types of comments in Java:

• single-line
• multi-line

Single-line comment:

Simply add a “//” at the beginning of a line to start a remark.

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!!!

Multi-line comment:

Simply add a “/*…….*/” at the beginning of each line to create a multi-line comment.

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!!!
