JavaFX模拟产品调查

Question

我正在对5种产品进行模拟调查。目前正在为高中学习JavaFX。任务是从1到5生成1000个随机数，我必须在代表10票的小圆圈中为每个客户选择打印结果。

编辑：我想打印一个＆＃39; O＆＃39;每生成10张选票，但只得到一张O＆＃39;即使有足够的生成数字。

    //Rounding up the numbers that have been generated
    int a = (int) Math.ceil(prodOne / 10.0);
    int b = (int) Math.ceil(prodTwo / 10.0);
    int c = (int) Math.ceil(prodThree / 10.0);
    int d = (int) Math.ceil(prodFour / 10.0);
    int e = (int) Math.ceil(prodFive / 10.0);

    //for-loop to print one 'O' for every 10 votes
    String s = "";
    for (int i = 0; i < a; i++){
        s += "O ";
    }
    lblProductOne.setText(s);

    s="";
    for (int i = 0; i < b; i++){
        s += "O ";
    }
    lblProductTwo.setText(s);

    s="";
    for (int i = 0; i < c; i++){
        s += "O ";
    }
    lblProductThree.setText(s);

    s="";
    for (int i = 0; i < d; i++){
        s += "O ";
    }
    lblProductFour.setText(s);

    s="";
    for (int i = 0; i < e; i++){
        s += "O ";
    }
    lblProductFive.setText(s);
}
