How to generate a random number in Java?

Question

Does anyone know how you can get a random number in Java? Or random ish, which is hard to predict?

Answer 1

/* There's an easy and simple way, just import the java.util.Random class and set the max and the lower limit implicitly */

import java.util.Random;
public class RandomNumbers
{
public static void main(String[] args) {
Random rand = new Random();
// 100 is the max limit, 1 is the min, modify it accordingly...
System.out.print(rand.nextInt(100)+1);
}
}

Answer 3

Figured it out

//first need to import a java.util:

import java.util.concurrent.ThreadLocalRandom

//then you can make the int with a random number:

int randomNumber = ThreadLocalRandom.current().nextInt(min, max+1);

//this worked for me :)

Answer 4

// edited ignore the other one 😁 //

import java.util.Random;

// main //

Random rnd = new Random();

int i [] = {1,2,3};
String z [] = {"a","b","c"};

int y = rnd.nextInt(i.length);

System.out.println( i[y]); //random int
System.out.println(z[y]); //random String
