Generates a random number for a specified range

To generate [10,20] random numbers, for example,

First, generate a random number of 0-20,

The random number between [0-10] is then obtained for (20-10+1) modulo,

And then add min=10,

The last generated is a random number of 10-20.

Import Java.util.Random;

public class Randomtest {
public static void Main (string[] args) {
int max=20;
int min=10;
Random random = new random ();

int s = random.nextint (max)% (max-min+1) + min;
System.out.println (s);
}
}

Andom.nextint (max) represents the generation of random numbers between [0,max] and then modulo (max-min+1).
