You must instantiate a Random object before using it.

import java.util.Random;

public class HelloWorld {
  public static void main(String[] args) {

    //instantiate a new object of Random class
    Random randomGenerator = new Random();

     int randomInt = randomGenerator.nextInt(10);

     System.out.println("Generated : " + randomInt);
  }
}

This didnt work out error; "randomnumber should be a string"

It can be a typo error.. but anyway it might be solved removing the System.out.println line
