I fixed your code but it creates an infinite loop when entering a number greater than 2 or less than 0. This should only happen on Sololearns code playground but on PC it should keep asking for input until you enter a number greater than 0 but less than 2. Figure out the fix.. https://code.sololearn.com/c5d53qbST72X/?ref=app

why not use if() as while() is a loop

This will probably produce the results you're looking for: import java.util.Scanner; public class Program { public static void main(String[] args){ Scanner s = new Scanner(System.in); int numberEntered; do { System.out.println("Please enter the row number (0-2) "); numberEntered = s.nextInt(); } while ((numberEntered < 0) || (numberEntered > 2)); System.out.println(numberEntered); } }

Maybe this code can help you. used if else instead of while loop. the number would not be displayed if it is not between 0 and 2 but would be displayed if it is in the range. https://code.sololearn.com/csS82irRjfMr/?ref=app
