I realize this is more java related than Android but this is the only forum I'm on. :) my trivia app has about 700 questions but I get an incredible amount of repeats due to random new random int w/e next int of the random. Could anybody help me make it more random?

I think you have to generate the Random number which is unique also, so that there is no repeatability of the question at that generated index.

Thanks for the response.

Random randNum = new Random();
int numUsed = randNum.nextInt(333);

So you have 700 responses but you only ask for a random number between 0-333.

Your code is as random as it's gonna get. You could save the last selected number and if the next number == that number then random() again, but saying that then it wouldn't be truly random!!
