How do I ensure that Scanner hasNextInt() asks for new input?

Question

New programmer here. This is probably a really basic question, but it\'s stumping me nevertheless.

What I\'m trying to do is write a method that supplies only one in

You were close: this works fine for me:

Scanner input = new Scanner(System.in); //construct scanner
while(!input.hasNextInt()) {
    input.next(); // next input is not an int, so consume it and move on
}
int finalInput = input.nextInt();
input.close(); //closing scanner
System.out.println("finalInput: " + finalInput);

By calling input.next() in your while loop, you consume the non-integer content and try again, and again, until the next input is an int.
