sorted, shuffled, reversed

Hello, I’m trying to write a program that takes in numbers until a sentinel value is entered then displays a sorted, shuffled and reversed?

So far this is what I have come up with.

I know I need to implement the comparator but I’m not sure how too.

Could you provide some feedback?

Thanks



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


Collection<Integer> list = new ArrayList<Integer>();

Scanner scan = new Scanner (System.in);

System.out.println (" Input Number : ( 0 to exit ) ");
int data = scan.nextInt();

int sum = 0;
while (data != 0) {
sum +=data;

System.out.println (" Input Number : ( 0 to exit ) ");
data = scan.nextInt();
list.add(data);
}
System.out.println (" The sorted numbers are ");
Collections.sort(list);
System.out.println (" The shuffled numbers are ");
Collections.shuffle((java.util.List<?>) list);
System.out.println (" The reversed numbers are ");
Collections.reverseOrder();
}
}

Rather than doing set up before the loop and then getting more input in the loop you can shorten it with something like this

Code:

---

int n;
while((n=in.nextInt())!= 0){
  //do stuff
}

What happens when you just pass the list into sort and shuffle? Look up what the reverseOrder method it. what does reversing the list imply? Some sort of sorting perhaps? What happens if you use it's comparator to sort a list?
