Gracias por tu aporte, justo tuve que hacer un trabajo sobre esto y me sirvió mucho tu código. Te muestro lo que hice

package signozodiaco;
import java.util.Scanner;

public class SignoZodiaco {

public static void main(String[] args) {
    int dia=0;
    int mes=0;
    Scanner leer = new Scanner(System.in);
    
    Signo nuevoSigno = new Signo(dia, mes);
    System.out.println("Ingrese dia");
    nuevoSigno.setDia(leer.nextInt());
    System.out.println("ingrese mes");
    nuevoSigno.setMes(leer.nextInt());
    nuevoSigno.fechaValida();
    nuevoSigno.fSigno();
    nuevoSigno.getSigno();
           
}
