سلام این هم برنامه ی عدد اول به صورت   UI

                int vorodi = Integer.parseInt(EdtInput.getText().toString());

                Edtoutput.setText("\t\t اعداد اول هستند  \n " + out_put);

            }
        });

    }


    protected ArrayList<Integer> Number_Aval(int number) {
        ArrayList<Integer> out1 = new ArrayList<Integer>();
        ArrayList<Integer> out2 = new ArrayList<Integer>();
        int compare, i, j, counter = 0, m = -1;
        for (i = 0; i < number; i++)
        {
            out1.add(i + 1);
        }

        for (j = number - 1; j >= 0; j--)
        {

            compare = 0;
            while (j >= compare) {
                if (out1.get(j) % out1.get(compare) == 0)
                {

                    compare++;
                    counter++;
                }
                else if (out1.get(j) % out1.get(compare) != 0)
                {
                    compare++;
                }
            }// End While

            if (counter <= 2)
            {
                m++;
                out2.add(m, out1.get(j));
                counter = 0;

            }
            else
                counter = 0;
        }// End for
        return out2;

    }

نمایش اعداد اول توسط خودم

        int adad = 50;
        int cunter;
        for (int n = 1; n < adad; n++) {
            cunter = 0;
            for (int p = 1; p < adad; p++) {
                if (n % p == 0) {
                    cunter++;
                    if (cunter < 3 && p == n)
                        Log.i("log", "Adad Aval= " + p);

                }
             }
        }
