how modulo works in stages

    public static void main(String[] args) {
        final int STAGE_1 = 0;
        final int STAGE_2 = 1;
        final int STAGE_3 = 2;


        int counter = 0;

        while(counter < 3 * 100) {
            switch(counter % 3) {
                case STAGE_1:{
                    System.out.println("Current bunch: " + (int) (counter / 3 + 1));

                    System.out.println("Stage 1");
                    break;
                }
                case STAGE_2: {
                    System.out.println("Stage 2");
                    break;
                }
                case STAGE_3: {
                    System.out.println("Stage 3");
                    break;
                }
            }


            counter++;
        }
    }
