Reference of a non static variable

I have class Employe that has variables like id , name ... and 2 other classes that inherit from Employe : Seller and Cashier. To calculate their salaries, I created a method in each one of Seller and Cashier but I need to access the name via the name getter method in Employe so I'd have :

System.out.println("The salary is "+Seller.getName() +" is : " +salary);

Once I type that, I get an error sayingI need to make the name variable to static, but I need it as non static since I'm creating multiple objects using the name variable. Any solution to this problem?

EDIT : This is the Employe class : 

public class Employe {
protected int id;
protected  String name;
protected String adresse;
protected int nbrHours;

public Employe () {
}

public Employe (int id, String name, String adresse, int nbHours)
{
    this.id=id;
    this.name=name;
    this.adresse=adresse;
    this.nbrHours=nbHours;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public  String getName() {
    return name;
}

public void setNom(String name) {
    this.name = name;
}

public String getAdresse() {
    return adresse;
}

public void setAdresse(String adresse) {
    this.adresse = adresse;
}

}

This is the Seller class : 

public class Seller extends Employe {
private int prime;
public Seller (int id, String name, String adresse, int nbHours,int prime)
{
    super(id,name,adresse,nbHours);
    this.prime=prime;
}

public int getPrime() {
    return prime;
}

public void setPrime(int prime) {
    this.prime = prime;
}

@Override
public String toString() {

    return super.toString() +" [prime=" + prime + "]";
}

public void salaireSeller ()
{
    int salaire = 0;
    if(nbrHours<160)
    {
    salaire = nbrHours * 10 + prime;
    System.out.println("La salaire de "+Responsable.getName() +" est : " +salaire);
    }
    else if(nbrHours >160)
    {
        int Extra= (160 - nbrHours) * 12;
        int salaire1 = 160 * 10000 + prime;
        salaire= Extra + salaire1;
        System.out.println("La salaire de "+Seller.getName() +" est : " +salaire);
    }

}

In the Main class I created a Seller object : 

Seller Sel1 = new Seller(2, "Alex", "Miami", 18, 200);

now I want to calculat its salary using the SalaireSeller() method in the Main class of course :

Sel1.salaireSeller();

but in the Seller class : 

System.out.println("La salaire de "+Responsable.getName() +" est : " +salaire);

it says I need to set Name to static, this will give every object the same name

I figuered out a solution, I just need to add the name to the toString() method in class Employee, then add the salary variable to the toString() method in Seller class, without System.out.println(..) in SalaireSeller().

or instead of Seller.getName(), I use this.getName() and it works.

You're certainly trying to access an instance variable from a static method.

What you want to do here is to create an instance of your class, then call the getName() method on the object created.

Seller sell = new Seller();
sell.setName("Jean-Paul"); // This is just an example
System.out.println("His name is " + sell.getName()); // Prints : His name is Jean-Paul

You need a Seller instance, to call getName() and getSalary() on.

Seller s = new Seller();
// ...
System.out.println("The salary is " + s.getName() + 
        " is : " + s.getSalary());
