How do I modify the php so that it appears in a single line when there is a condition? Do an IsSelected in a ComboBox with the SelectedValue [UWP]

I think the error is because it is badly invoked, either by the part that needs a constructor, or that you do not have methods to enter the data properly.

I guess the "Date" class looks like this:

public class Fecha {
    private int dia, mes, anio;

    public void setDia(int dia) {
        this.dia = dia;
    }

    public void setMes(int mes) {
        this.mes = mes;
    }

    public void setAnio(int anio) {
        this.anio = anio;
    }
}

If so, you would have to add the values as follows:

public class main {

    public static void main(String[] args) {
        Fecha f1 = new Fecha();
        f1.setAnio(2018);
        f1.setMes(10);
        f1.setDia(04);

        Fecha f2 = new Fecha();
        f2.setAnio(2018);
        f2.setMes(10);
        f2.setDia(04);

        if (f1.equals(f2)) {
            System.out.println("Son iguales");
        } else {
            System.out.println("Son distintas...");
        }
    }
}

Another way is adding a constructor to the "Date" class:

public class Fecha {
    private int dia, mes, anio;

    public Fecha(int dia, int mes, int anio) {
        this.dia = dia;
        this.mes = mes;
        this.anio = anio;
    }
}

And when invoked, they are entered in the following way:

public class main {

    public static void main(String[] args) {

        Fecha f3 = new Fecha(04, 10, 2018);
        Fecha f4 = new Fecha(04, 10, 2018);

        if (f3.equals(f4)) {
            System.out.println("Son iguales");
        } else {
            System.out.println("Son distintas...");
        }
    }
}
