What I am trying to get is a random number generator that will produce five lines of 5 random numbers 1 through 70 and one more number 1 through 25 like a mega millions ticket.
import java.util.Arrays;
import java.util.Collections;
import java.util.Random;
public class MegaMillions {
public void play() {
Random rand = new Random();
int[] numbers = new int[5];
for(int i = 0; i < 5; i++) {
numbers[i] = rand.nextInt(69) + 1;
Collections.shuffle(Arrays.asList(numbers));
Arrays.sort(numbers);
System.out.print(numbers[i] + " ");
}
Collections.shuffle(Arrays.asList(numbers));
int megaBall = rand.nextInt(24) + 1;
System.out.println("(" + megaBall + ")");
}
}
Here is an example of what I'm getting:
0 0 21 21 35 (1)
0 0 16 26 32 (9)
0 0 39 39 53 (3)
0 0 22 37 51 (14)
0 0 18 18 60 (14)
My understanding was that Collections.shuffle should take care of any repeating integers and Arrays.sort should put in numerical order.
