Java scanner.nextInt() and read.nextInt()

Question

As far as I learned,
Scanner scanner = new Scanner(System.in);
is a method to ask the user to give input.

And to use this input, I should use
int number = scanner.nextInt();
But I also saw a method below from practice.
int number = read.nextInt();

What's 'scanner.nextInt' and 'read.nextInt', and what do they do?
