Java: Random number generator?

FatB

Could any one please help me, I know this may seem trivial to some but as I have only started studying java this year, I am finding this difficult!

I want to create an applet which will have a button that when pressed will generate a random* number between 1 and 500!

I know that there is a utility for this as i have seem it incorperated in a dice roll program!

Thanks in advance!
Willie



p.s. i have scoured the Internet already!

* random = to system clock will do (thats how the utility works)

take a look at
java.util.Random
if you have any questions relating to using this class, I will be happy to help. (others too im sure)

This'll do it:

int randNumber=(int)(Math.random()*499.0)+1;

or else you can use the Random class like Podgeen said - seed it with the system time:

Random r=new Random(System.currentTimeMillis());
int randNumber=r.nextInt(500)+1;

for (int i=0; i<500; i++)
int n = (int)(Math.random()*1000);

somethin like that should do it
