How to generate a specified range of random numbers in Java _java

To generate a random integer between [Min,max],

Copy Code code as follows:

Package Edu.sjtu.erplab.io;

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);
}
}

Random.nextint (max) represents the random number that is generated between [0,max] and then modulo (max-min+1).

To generate [10,20] random numbers as an example, first generate 0-20 of the random number, and then the (20-10+1) modulo to get [0-10] between the random number, and then add min=10, the last generation is 10-20 of random numbers
