Wie füge ich verschiedene Kommentare in Java-Code hinzu?

public class SingleLineComment {
   public static void main(String[] args) {
      // To print output in the console
      System.out.println("Welcome to Tutorials Point");
   }
}

public class MultiLineComment {
   public static void main(String[] args) {
      /* To print the output as Welcome to Tutorials Point
         in the console.
      */
      System.out.println("Welcome to Tutorials Point");
   }
}

/**
   This is a documentation comment.
   This class is written to show the use of documentation comment in Java.
   This program displays the text "Welcome to Tutorials Point" in the console.
*/
public class DocumentationComment {
   public static void main(String args[]) {
      System.out.println("Welcome to Tutorials Point");
   }
}
