//Recommend reseeding within methods
static Random rand = new Random();
public static void fillInt( int[] fillArray ) {
//seeds the random for a new random each method call
rand.setSeed(System.currentTimeMillis());
for(int i = 0; i < fillArray.length; i++)
{
fillArray[i]= rand.nextInt();
/* for loop to check to make sure that none of the previous
numbers added are the same as the one just added. */
for (int j = 0; j < i; j++)
{
/* if so we need to redo the last random number by
moving i back one index to be re-set */
if (fillArray[i] == fillArray[j])
{
i--;
}
}
}
}
