I have an attribute of type enum {V, M} and I have to assign the value through a combox from a swing application that I am doing from another class of another package, the fact is that I do not know how to invoke the attribute from its class to that of the application within the event method.
Could you give me an example?
Surely with this example you can guide yourself better. Enum class
public enum DiasSemanas {
LUNES, MARTES, MIERCOLES, JUEVES, VIERNES, SABADO, DOMINGO;
}
Then a class that implements it
public class Enumeraciones {
public Enumeraciones() {
super();
}
public void actividadesDiarias(DiasSemanas ds) {
switch(ds) {
case LUNES:
System.out.println("Es el primer dia de la semana");
break;
case MARTES:
System.out.println("Es el segundo dia de la semana");
break;
case MIERCOLES:
System.out.println("Es el tercer dia de la semana");
break;
case JUEVES:
System.out.println("Es el cuarto dia de la semana");
break;
case VIERNES:
System.out.println("Es el quinto dia de la semana");
break;
case SABADO:
System.out.println("Es el sexto dia de la semana");
break;
case DOMINGO:
System.out.println("Es el septimo dia de la semana");
break;
default:
System.out.println("Opcion no valida...!!!");
break;
}
}
and finally I execute it from a main class
public class Ejemplos {
public static void main(String[] args) {
// TODO Auto-generated method stub
Enumeraciones enumeraciones = new Enumeraciones();
enumeraciones.actividadesDiarias(DiasSemanas.LUNES);
enumeraciones.actividadesDiarias(DiasSemanas.MIERCOLES);
String[] lista = { "Lunes", "Martes", "Miercoles", "Jueves", "Viernes","Sabado", "Domingo" };
JComboBox combo = new JComboBox(lista);
combo.setSelectedIndex(0); // establecemos el primer valor por defecto
combo.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
System.out.println("Evento");
if (combo.getSelectedIndex() == 5) {
enumeraciones.actividadesDiarias(DiasSemanas.SABADO);
}
}
});
JFrame ventana = new JFrame();
ventana.getContentPane().setLayout(new FlowLayout());
ventana.getContentPane().add(combo);
ventana.pack();
ventana.setVisible(true);
ventana.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
}
Here only what you have left is in this last class to implement the JComboBox
Thank you very much!
I think I have the same, but I still get an error. I detail it a little summarized:
On the one hand I have the class with the enum attribute:
public class Medicos{
private enum Respuesta {S,N};
public void eleccionResp(Respuesta r){
switch(r) {
case S:
r = Respuesta.S;
break;
case N:
r = Respuesta.N;
break;
}
}
On the other hand I have the class with the application and a method with the event:
private void jCB1ActionPerformed(java.awt.event.ActionEvent evt) {
Medicos m5 = new Medicos();
int i = jCB1.getSelectedIndex();
if(i == 0){
m5.eleccionResp(r.S));// Aquí me da error (No puede encontrar la variable r)
}else{}
}
I miss something with the variable that I can not find out ...
