So, i have the superclass Persona, and subclasses, Estudiante and Docente. The attributes nombre,cedula,mail are attributes that i wanted to have on Estudiante and Docente because they both have them, but since both Estudiante and Docente are Persona's, i can use inheritage. All these objects have their get/set and tostring methods. The last code i posted, is an UI that i have. I want to press a button and create an Estudiante, but i cant, because it tells me that im giving more arguments that the ones that i can give, so.. how do i do it? I hope i explained myself well.
I haven't tried anything since i don't really know what to try. The first time i wrote that code i didnt thought about using this super class Persona, but i was told that i absolutely have to do it like that.
public class Estudiante extends Persona{
private int numero;
private int semestre;
public class Docente extends Persona {
private int anoingreso;
public class Persona {
private String nombre;
private int cedula;
private String mail;
private void BotonCrearEstudianteActionPerformed(java.awt.event.ActionEvent evt) {
Estudiante=new Estudiante(NombreEstudiante,CedulaEstudiante,MailEstudiante,NumeroEstudiante,SemestreEstudiante);
I expect to create an Estudiante in this case, but im going to create Docente's too, and later make teams with many of those two, but i can't because im giving too many arguments as i stated before.
Inside each class you also need to have a constructor- basically what you use to define how one of those objects is created. Like this:
public class Persona{
private String nombre;
private int cedula;
private String mail;
public Estudiante(/*Insert the parameters you need, but do not call them by the same thing as your instance variables above*/){
/*this block will execute when you create an Estudiante object*/
}
}
But when you get to the child classes (i.e. Estudiante and Docente), you can use the super() method inside the constructor, which on call will run the parent class' constructor.
