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

Question

Usage of scanner in Java class

Answer 1

Usually, we create only an instance of Scanner

Answer 2

what do you mean by that ? if we can instatiate many Scanner in one class ? or calling one or more scanner name ?

Answer 3

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.

Answer 4

Yes I mean instating more than one scanner in one class, would it cause any problem??
