Class & Properties - Java

I am new to java and have been set a task to create a class called Manual along with some properties shown in the question below:

"1. Design a class Manual with the following properties:

serial number - string, - default:??????

title - string, - default: Untitled

author - string, - default: Unknown

Write a constructor and a method to print details of a Manual on the console. "

I have been working on this task and so far I have this:

public class Manual {

    String serialNumber, title, author;

    public Manual(){
        serialNumber = "??????";
        title = "Untitled";
        author = "Unknown";
    }

}

Would anyone be able to let me know if my working so far is correct and also how I might be able to complete the last line referring to a constructor / print method.

Thank you

Other than that print, you need to have a main method to run.

public class Manual {

    String serialNumber, title, author;

    public Manual(){
        serialNumber = "??????";
        title = "Untitled";
        author = "Unknown";
    }

public void printDetails(){
   System.out.println("S.no= " +serialNumber+" Title= "+ title+"author= "+author)

}

public static void main(String [] args){
        Manual man= new Manual();
        man.printDetails();
    }

}

Edit after comment:

I just tried to give a mock code and , you must aware of the access modifiers to your members in the class. This is what your actual task. Learn them and experiment with them.

I wrote a small tutorial on the same, try to read and understand. Default access modifier in Java (or) No access modifier in Java

Good luck.

You are correct so far. For the printing you should use 

System.out.println("Manual details : ");
System.out.println("Serial Number : "+serialNumber);
System.out.println("Author : "+author);
System.out.println("Title : "+title);
