Random numbers without repetition

Hi

 

Can anyone suggest a pseudo code, to get the random number without repetition?

 

I have 80 numbers, where i need to pick 20 random numbers out of those 80 and display them on VF page.

But there should be no repetition in the picked 20 random numbers.

 

 

Thanks.

Hey

Set<Integer> randomNumbers = new Set<Integer>();
while(randomNumbers.size()<20) {
  Decimal randomNumber = (Math.random()*80)+1;
  randomNumbers.add(randomNumber.intValue());
}

Enjoy!
