Hi guys I am not sure why my output is not printing the original number that the user inputs instead it prints 0.
For example, if the user enters the number 226689, the expected out put is supposed to show:
Enter a number to be reversed:The reverse of 226689 is 986622
However, my output shows:
Enter a number to be reversed:The reverse of 0 is 986622
Here's my code:
import java.util.Scanner;
public class ReverseDigits {
public static void main ( String args[] ) {
ReverseDigits reversal = new ReverseDigits();
reversal.reverseNumber ();
}
public void reverseNumber() {
Scanner input = new Scanner (System.in);
int num;
int digit;
int rev = 0;
System.out.printf("Enter a number to be reversed:");
num = input.nextInt ();
while(num != 0) {
digit = num % 10;
rev = rev * 10 + digit;
num /= 10;
}
System.out.printf("The reverse of %d is %d", num, rev);
}
}
