How do you create a while loop that goes back to a Scanner request for user input?

Question

I'm trying to make a loop that returns an entry in an array when the user inputs a number within a certain ragne. If I assign a variable to the Scanner before the loop, I can't go back to it if the user input isn't inside the range, If I put it inside the loop, the variable isn't defined yet when used in the loop parameters. Any ideas?

Answer 1

Do you mean something like this?

int i = 0;

while(i != outside range){
i = yourScanner.nextInt();
//do something with i
}

But it is not possible in Sololearn. You have to use your IDE on your PC.

Answer 2

That is exactly what I needed to know. I was assigning the variable to the Scanner before the loop. I didn't even think of just giving it a different initial value. Thank you.
