//Aquí guardo los datos ingresados por teclado
private void botonGuardarActionPerformed(java.awt.event.ActionEvent evt) {

//Y finalmente llamo a este metodo pero los datos me salen en null

            Linea2 =" Nombre: "+ persona.Nombre + " \n " +"Apellido.: "+ persona.Apellidos + " \n " +"Rut.........: "+ persona.Rut + " \n "+"Telefono: " + persona.Telefono;

            Linea = Linea + Linea2 + "\n";
        }
        return Linea;
    }

}

@Franco Rolando imagine you mean this class

public class Persona {

    public String Nombre;
    public String Apellidos;
    public String Rut;
    public String Telefono;

    public Persona() {

    }

    public Persona(String Nombre, String Apellidos, String Rut, String Email, String Telefono) {

java

I can see that you did the same program with which I currently have problems. How did you solve the error that agenda.GuardarPersona(persona); and JOptionPane.showMessageDialog(null,agenda.MostrarAgenda()); the term agenda does not appear in green ?. I do not know what to add.

In advance, I appreciate your response.

Android Studio 3.1.3 recognizes as "null my images" "UnicodeDecodeError" when starting the python shell on the Windows cmd

It is already solved, I had to initialize, I needed to add this:

    nombre=Nombre;
    apellidos=Apellidos;
    rut=Rut;
    telefono=Telefono;

}

Thanks, this is my first question in stack overflow, I do not know how to score, I do not even have a reputation to comment. Greetings
