0 is included in the generated random number, so we have to keep calling nextInt method until we get a value between 1 and 10. You can extend the above code to generate the random number within any given range.
import java.util.Random; public class RandomRangeDemo { public static int randomNumberGenerator(int min, int max) { Random r = new Random(); double randomNum = r.nextDouble(); int result = (int)(randomNum * (max - min)) + min; return result; } public static void main(String[] ...

One of them is the Math.random() method, which returns a random value between 0..1. Typically, it's used to generate random percentile values. However, in a similar vein to the Random.nextInt() hack - you can utilize this functionality to generate any integer in a certain range: int...
I am looking for a random number generator that is biased towards giving numbers "furthest away" from a set of already selected numbers. For example, if my range is [1, 50] and I pass in a set of numbers such as (1, 20, 40), then I would want the generator to "prefer" ...

我们一般使用随机数生成器的时候,都认为随机数生成器(Pseudo Random Number Generator, PRNG)是一个黑盒: 这个黑盒的产出,一般是一个数字。假设是一个 int 数字。这个结果可以转化成各种我们想要的类型,例如:如果我们想要的的其实是一个 long,那我们可以取两次,其中一次的结果作为高 32 位,另一次结果作为低 32 ...
s(100)returns a stream of 100intvalues. These are not necessarily the exact same values that would have been returned if insteadr.nextInt()had been called 100 times; all that is guaranteed is that each value in the stream is chosen in a similar pseudorandom manner from the same range....
