Java - Generate 2 Number In Specific Numbers : I want generate 2 numbers in specified numbers, I wrote this code and not work, can anybody suggest a better solution ?

==========================================
    public class l{
    public static void main(String[] args) {

            int[] lottery = new int[2];
        int randomNum;

        for (int i = 0; i < 3; i++) {
             randomNum = (int) (Math.random() * (3,9,25,41,43,50,68)); // Random     number created here.
             for (int x = 0; x < i; x++) {
                 if (lottery[x] == randomNum) // Here, code checks if same random number generated before.
            {
                randomNum = (int) (Math.random() * (3,9,25,41,43,50,68));// If random number is same, another number generated.
                x = -1; // restart the loop
            }

        }
        lottery[i] = randomNum;
    }

    for (int i = 0; i < lottery.length; i++)
        System.out.print(lottery[i] + " ");

}
}

Thanks
