Usually, we create only an instance of Scanner

On Sololearn you will get a problem.
You can try it on the playground:
Scanner input = new Scanner...
int i = input.next ();
Scanner scan = new Scanner...
i = scan.nextInt ();
Should not work. But on your pc with your own ide it should be possible.
But normally you create only one object of scanner:
Scanner input = new Scanner...
int x = input.nextInt ();
String text = input.nextLine ();
whatever input you need.
