Is there a problem with instantiating more than one Scanners for one class??

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.
