How do I calculate a winning combination in Primitiva (Java)?

  • 772

I need to know how I can calculate a winning combination in Java is in the Primitive

The code that I show you here, is what I have done so far, I need help to be able to calculate the winning combination, since it is costing me a lot to understand it and be able to do it, I was doing it by myself, if someone can help me, I would greatly appreciate it

The class where it is in CalculateWinningCombination is that part that I don't know how to do

public void init(){
    System.out.println("***** PRIMITIVA ******");

    int[] apuesta = introducirApuesta();

    int[] combinacionGanadora = calcularCombinacionGanadora();

    if (combinacionGanadora!=null) {
        System.out.println("La combinacion ganadora es: ");
        for (int i = 0; i < combinacionGanadora.length - 1; i++) {
            System.out.print(combinacionGanadora[i] + " ");
        }
        System.out.println("Reintegro: " + combinacionGanadora[combinacionGanadora.length - 1]);
    }

    int premio = comprobarAciertos(apuesta, combinacionGanadora);
    System.out.println("Tu premio es: "+premio+" €");

}

public int[] introducirApuesta(){
    Scanner input=new Scanner(System.in);
    int random=(int)(Math.random()*0+9);
    System.out.println("Introduce tu apuesta");
    int [] apuesta=new int[7];
    for (int i=0;i<apuesta.length;i++){
        apuesta[i]=input.nextInt();

    }
    System.out.println("La Apuesta introducida es");
    System.out.println(Arrays.toString(apuesta)+" "+random);

    return apuesta;
}

public int[] calcularCombinacionGanadora(){
   int [] combinacion=new int[7];
        Random rnd=new Random();


    return combinacion;
}

    First of all, I agree with one of the comments,

    int random=(int)(Math.random()*0+9);

    It will always return 9, also, I'm not sure what the point of this random number is in the enter bet function.

    As for calculating the winning combination, from what I understand it should come down to getting a combination of 7 random numbers within a certain range.

    For example, suppose they must be integers between 1 and 49. This could be a solution.

    public bool disponible(int numero, int[] tomados){
   for(int i = 0; i < tomados.length; i++){
      if(numero == tomados[i]){
         return false;
      }
   }
   return true;
}

public int[] calcularCombinacionGanadora(){
   int [] combinacion=new int[7];
   //Inicializando el array
   for(int i=0; i < 6; i++){
      combinacion[i] = -1;
   }
   //Rellenando el array
   for(int i=0; i < 6; i++){
      numero = (int)(Math.random() * 49 + 1);
      while(!disponible(numero, combinacion)){
         numero = (int)(Math.random() * 49 + 1);
      }
      combinacion[i] = numero;
   }
   combinacion[6] = (int)(Math.random() * 10)
   return combinacion;
}
