java - 以特定数字为增量生成双随机数

Question

 private static double getSliceQuantityinRange(double min, double max) {
    double range = max - min;
    double scaled = randomGenerator.nextDouble() * range;
    double shifted = scaled + min;
    return Double.valueOf((df.format(shifted)));
  }

最小值和最大值将以百万为单位。这给出了一个范围之间的随机数。但我想要的是步长为 100,000 ( 100000) 的随机数。如何实现这一目标？

Answer 1

这是一个例子:

public static void main(String[] args) {
    System.out.println(getSliceQuantityinRange(35000000, 52000000, 100000));
}

private static double getSliceQuantityinRange(double min, double max, double step) {
    int range = (int)((max - min) / step);
    double scaled = randomGenerator.nextInt(range) * step;
    double shifted = scaled + min;
    return Double.valueOf((df.format(shifted)));
}
