Generate Two Numbers from a Specified List of Numbers

I want to generate two numbers in a specified list of numbers. I wrote this code but it does not work. Can anyone suggest a better solution?

public classl {

    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] + " ");
        }

    }
}
