Use the Lottery class to the left as the superclass. Create the PowerBall class as a subclass of Lottery. Override the shuffle method so that it returns an ArrayList of six random integers up to but not including 100.

CODE:

import java.util.ArrayList;
import java.util.Random;

class Lottery {
public ArrayList shuffle() {
Random r = new Random();
ArrayList nums = new ArrayList();
for (int i = 0; i < 5; i++) {
int num = r.nextInt(20);
nums.add(num);
}
return nums;
}
}

//add class definitions below this line

class PowerBall extends Lottery {
public ArrayList shuffle() {
Random r = new Random();
ArrayList nums = new ArrayList();
for (int i = 0; i < 6; i++) {
int num = r.nextInt(100);
nums.add(num);
}
return nums;
}
}

//add class definitions above this line

public class Exercise1 {
public static void main(String[] args) {

//add code below this line

PowerBall p = new PowerBall();
System.out.println(p.shuffle());

//add code above this line
}
}
