I get the non static method cannot be referenced from a static context, I forget how to overcome this as it's been a while since I have used java.

I need to create the sorting method and test it in the same file.

Option 1: Make the Sort function static

public static int[] Sort(int[] input)

Option 2: Create an instance of the class

 public static void main(String[] args)
 {
 Sorting s  = new Sorting();
 System.out.println(Arrays.toString(s.Sort(array to be sorted)));
 }

Make Sort a static method!

public static int[] Sort(int[] input)
...

Arrays.toString(new Sorting().sort(array to be sorted))
