How can I add these variables that share almost the same name without the need to add them line by line?

Question

This is the class where I declare several INT variables that contain positions and then add them into an arraylist but I would like to do it in some kind of loop and not add line by line

class Ejecutar {

    
    private int B1 = 0;
    private int B2 = 2;
    private int B3 = 3;
    private int B4 = 8;
    private int B5 = 9;
    private int B6 = 11;
    private int B7 = 12;
    private int B8 = 17;

    
    private  ArrayList<Integer> arreglo_posiciones = new ArrList<Integer>();

    
    public Ejecutar() {
        
    }
    
    
    public void cargarArregloPosiciones() { 
        this.arreglo_posiciones.add(this.B1);
        this.arreglo_posiciones.add(this.B2);
        this.arreglo_posiciones.add(this.B3);
        this.arreglo_posiciones.add(this.B4);
        this.arreglo_posiciones.add(this.B5);
        this.arreglo_posiciones.add(this.B6);
        this.arreglo_posiciones.add(this.B7);
        this.arreglo_posiciones.add(this.B8); 
    }

}

I want to add these variables with some kind of loop without the need to add them line by line

Do you need the positions as class members? or can you directly put them into the array? — Yonatan Karp-Rudin, Nov 22 '22 at 13:55
this might help you building a List of the fields of the class: https://stackoverflow.com/questions/16295949/get-all-fields-even-private-and-inherited-from-class — Stultuske, Nov 22 '22 at 13:55
Yes, as @Stultuske you can use *reflection* to solve your problem, there is no other way except if you want to change your logic. — Youcef LAIDANI, Nov 22 '22 at 13:58
@Stultuske Do you have any idea if it loads the array sequentially to the variables? That is, I would add how I have it in the code, right? — imnachox2, Nov 22 '22 at 14:28
