Random Number

I want to generate a random number between 1 & 97, then message the player:
ChatColor.RED + "Your ID is" + ChatColor.GREEN + the random number
How would I do that?

 

Code:java

 
Random rnd = new Random();
 
int yourId = rnd.nextInt(97) + 1; //nextInt() will return a sudo-random number from 0 to # - 1

 

I wouldn't depend on that if you're assigning IDs to players, as it's extremely likely to repeat itself. You'd need to make sure each player had a unique ID.

 

Why not just,

Code:java

int random = ((int) Math.random() * 97) + 1;
player.sendMessage(ChatColor.RED + "Your ID is " + ChatColor.GREEN + Integer.toString(random))

 

Code:java

SecureRandom sr = new SecureRandom();
UUID uuid1 = UUID.randomUUID();
String uuids = uuid1.toString();
int length = uuids.length();
StringBuilder sb = new StringBuilder(uuids);
for (int x = 0; x <= length/2; x++){
length = sb.length();
sb.deleteCharAt(sr.nextInt(length));
sb.reverse();
}
String s = sb.toString();
s = s.replaceAll("-", "");
return s;
 

Is what I use if I want a REALLY random id. It's really resource intensive, but it's probably the most random string you're going to get.
