Sorting three numbers

public class Solution {
public static void main(String[] args) throws Exception {
Scanner sc = new Scanner(System.in);
ArrayList<Integer> list = new ArrayList<Integer>();
while(sc.hasNextInt()){
list.add(sc.nextInt());
}
Integer [] nums = list.toArray(new Integer[0]);
for(int i = 0; i < nums.length; i++){
System.out.println(nums[i]);
Collections.sort(nums[i],Collections.reverseOrder());
System.out.println(nums[i]);
}
}
}
How can I modify this to where I can sort this arraylist descending

Collections.sort() takes a collection in as the first argument, not a value at an index in an array.
*hint* list in the above code is a collection, nums is not.
