Why is not the System.out.println that is in the while printed on the console?

package Ejercicio15;

public class AcumuladorInteractivo {
private double nota;

//GET AND SET

public double getNota() {
    return nota;
}
public void setNota(double nota) {
    this.nota = nota;
}

//METODOS

public double media(double nota) {
    double nuevaNota = 0;
    double notaTotal = 0;
    do {
        System.out.println("Introduce un numero: ");
        notaTotal = notaTotal + nota; 
        nuevaNota++;
    }while(nota <= 0);
    return notaTotal/nuevaNota;
}
}

Class with main method

package Ejercicio15;
import java.util.*;
public class AcumuladorInteractivoApp {
   public static void main(String[]args) {
      AcumuladorInteractivo a = new AcumuladorInteractivo();
      Scanner sc = new Scanner(System.in);
      a.media(sc.nextDouble());
      sc.close();
 }
}
