@mik., I have 2 tutorials on the site -- one for displaying values (whether text or graphically) and one for scrolling. To help find them, they both have olive green thumbnails with black text (with the word 'tutorial').
From source (comments are mine):
-----------------
// importing class
import java.util.Random;
// creating Random object
private static Random randomGenerator = new Random();
// using Random object
public static int getRandomNumber(int limit)
{
return randomGenerator.nextInt(limit);
}
As far as random, I used it here because I wanted to ensure a new random seed value each and every loading (greenfoot probably does it in a somewhat similar manner, but anyway ...).
The words omitted are the Hangman puzzle answers (not given for obvious reasons).
Little difference between the two randoms. In fact, the method Greenfoot.getRandomNumber(int) uses java.util.Random in its implementation.
@Roshan123, it is just a matter of comparing user to a list during logging in. List is literal code that would be updated as needed. I used a BannedWorld set active if banned user tries to log in.
