Storing information using a constructor with class type parameters

I have the following exercise:

In a port, moorings (parking space) for boats are rented. For each rental, the name, the client number, the number of days of rental, the position of the mooring and the boat that occupies it are stored. A boat is characterized by its registration, its Slovak (in meters) and the year of manufacture. The boats differ according to their type and characteristics in:

• Sailboats: number of masts.

• Sports boats: power in the engine.

• Luxury yachts: engine power and number of cabins.

The rental cost is calculated by multiplying the number of days of occupation by the daily cost, which varies according to the type of boat:

• For sailboats it is calculated by multiplying the number of masts by $15.

• For boats it is calculated by multiplying the meters of Slovakia by $35.

• For yachts it is calculated by multiplying the number of cabins by $17.

1. Use inheritance to implement classes and their relationships.

2. Generate a test class that:

   • Enter the information for each type of ship.
   • Using polymorphism compute the rent paid by the customer.
   • Using an interface displays the data for each of the ship types.

I have made the following code, but I have some questions. In principle I have to create a test class so that the user can enter information for each of the types of boats (sailboats, luxury yachts, boats) and I already entered that information, but not as expected.

I wanted to send all the information of the sailboat through the constructor of the class Renta, ie Renta(String nombre, String posicion, int numDias, int numCliente, Barco barco), but I don't know how to send it information through the attribute barco, so to solve the problem I created one interfaceso that I could store and print the data of the sailboat.

interface Adicional {
    String muestraDatos();
    double costoRenta();
}

class Renta implements Adicional {

    private String nombre, posicion;
    private int numDias, numCliente;
    private Barco barco;

    Renta() {
    }

    Renta(String nombre, String posicion, int numDias, int numCliente, Barco barco) {
        this.nombre = nombre;
        this.posicion = posicion;
        this.numDias = numDias;
        this.numCliente = numCliente;
        this.barco = barco;
    }

    public String muestraDatos() {
        return nombre + " " + posicion + " " + numDias + " " + numCliente + " " + barco;
    }

    public double costoRenta() {
        return 0;
    }

    String getNombre() {
        return nombre;
    }

    String getPosicion() {
        return posicion;
    }

    int getNumDias() {
        return numDias;
    }

    int getNumCliente() {
        return numCliente;
    }

    Barco getBarco() {
        return barco;
    }

    void setNombre(String n) {
        nombre = n;
    }

    void setPosicion(String p) {
        posicion = p;
    }

    void setNumDias(int n) {
        numDias = n;
    }

    void setNumCliente(int n) {
        numCliente = n;
    }

    void setBarco(Barco barco) {
        this.barco = barco;
    }
}

abstract class Barco {

    private int matricula, year;
    protected double eslova;//en metros

    Barco(int matricula, int year, double eslova) {
        this.matricula = matricula;
        this.year = year;
        this.eslova = eslova;//longitud del barco

    }


    public double costoRenta() {  
        return 0;
    }            

    public String muestraDatos() {

        return matricula + " " + year + " " + eslova + " ";
    }
}

class Velero extends Barco {

    private int numMastiles;

    Velero(int matricula, int year, double eslova, int numMastiles) {
        super(matricula, year, eslova);
        this.numMastiles = numMastiles;
    }

    public String muestraDatos() {
        return super.muestraDatos() + " " + numMastiles;
    }

    public double costoRenta() {
        return 15 * numMastiles;
    }
}

abstract class BoteConMotor extends Barco {

    protected double potenciaMotor;

    BoteConMotor(int matricula, int year, double eslova, double potenciaMotor) {
        super(matricula, year, eslova);
        this.potenciaMotor = potenciaMotor;
    }

    public String muestraDatos() {
        return super.muestraDatos() + " " + potenciaMotor;
    }
}

class Embarcaciones extends BoteConMotor {

    Embarcaciones(int matricula, int year, double eslova, double potenciaMotor) {
        super(matricula, year, eslova, potenciaMotor);
    }

    public double costoRenta() {
        return 35 * eslova;
    }
}

class YateLujo extends BoteConMotor {

    private int numCamarotes;

    YateLujo(int matricula, int year, double eslova, double potenciaMotor, int numCamarotes) {
        super(matricula, year, eslova, potenciaMotor);
        this.numCamarotes = numCamarotes;
    }

    public String muestraDatos() {
        return super.muestraDatos() + " " + numCamarotes;
    }

    public double costoRenta() {
        return numCamarotes * 17;
    }
}

public class AlquilacionBARCOS {

    public static void main(String[] args) {

        Scanner r = new Scanner(System.in);

        Renta s = new Renta();
        Barco b[] = new Barco[3];

        System.out.println("Introduzca la informacion para el barco velero\n");
        System.out.println("nombre del cliente");
        String nam = r.nextLine();
        s.setNombre(nam);
        System.out.println("num. de cliente");
        int n = r.nextInt();
        s.setNumCliente(n);
        System.out.println("num. de dias de renta");
        int m = r.nextInt();
        s.setNumDias(m);
        System.out.println("posicion de amarre");
        r.nextLine(); 
        String p = r.nextLine();
        s.setPosicion(p);
        System.out.println("matricula:");
        int q = r.nextInt();
        System.out.println("eslova:");
        double w = r.nextDouble();
        System.out.println("year de fabricacion:");
        int k = r.nextInt();
        System.out.println("num. de mastiles:");
        int v = r.nextInt();

        b[0] = new Velero(q, k, w, v);
        System.out.println(b[0].muestraDatos() + " " + b[0].costoRenta()+" "+s.muestraDatos());
     }
}

My question is: how to send all the information about some type of ship using this constructor Renta(String nombre, String posicion, int numDias, int numCliente, Barco barco)?
