java - 如何将一个范围内的两个随机数相加？

Question

我的要求:--

The sum of the two random numbers will be 100..
      sum=random_no1 + random_no2  (the sum will be exact 100)

所以，我尝试过:--

Random r = new Random();
        int Low = 10;
        int High = 100;
        int R = r.nextInt(High-Low) + Low;

    Random r1 = new Random();
    int Low1 = 10;
    int High1 = 100;
    int R1 = r1.nextInt(High1-Low1) + Low1;

但是我如何定义总和？

我不明白..请帮助我..

Answer 1

好吧，根据您的要求，我建议您从 100 中减去第一个随机数。然后您将得到两个具有该总和的随机数。最后，Java 命名约定是小写字母在前。就像，

Random r = new Random();
int low = 10;
int high = 100;
int r1 = r.nextInt(high - low) + low;
int r2 = 100 - r1; // <-- so that r1 + r2 is 100
