Pass value to another class

I have in a class called Entrance the following program:

public class Entrada {

    public static void main(String[]args) throws IOException{

        Scanner lector = new Scanner (System.in);
        String fichero ;            
        System.out.println("Posa el nom del ficher:");
        fichero = lector.nextLine();
        File file = new File(fichero); 
        EscriureLlibreria(fichero);


    }

How can I pass the file value to the Sort class?

    public class Sortida {


    public static void main(String[] args) {

 try {
        JAXBContext context = JAXBContext.newInstance(Llibreria.class);
        Unmarshaller ums = context.createUnmarshaller();
        // Mostrem el fitcher creat previament a la clase Entrada.
        Entrada.EscriureLlibreria(fichero);
        JAXBElement<Llibre> rootElementCast = ums.unmarshal(new StreamSource(new File(fichero)), Llibre.class);

        //Mostrem totes les característiques que hem demanat per teclat.
        Llibre llibreria = rootElementCast.getValue();
            System.out.println("Autor:" + llibreria.getAutor());
            System.out.println("Nom" + llibreria.getNom());
            System.out.println("Editorial" + llibreria.getEditorial());
            System.out.println("ISBN:" + llibreria.getIsbn());
    } catch (JAXBException e) {
        e.printStackTrace();  
}
        }
}

With file value I refer to Public Class Entry { inside the main I get a value that is the file.

The value is that it gives me a file entered by the user, because that value I want it in:

public class Sortida {

inside your main to use it to read it.

something like this:

Entry.EscriureLlibreria ( file );         JAXBElement rootElementCast = ums.unmarshal (new StreamSource (new File ( file )), Llibre.class);
