In my Java class I must create a program that takes a 5 digit number from keyboard input and tells you if the number that was inputted is a palindrome or not. I am very close to making it work, but I am having trouble deriving the 5th digit. I am thinking that is why the program will not calculate if the value is a palindrome or not because it cannot account for the 5th digit. When I use a 4 digit number it works fine. The code does compile correctly. I just need a little guidance to ensure I am on the right path. Here is my code.
CODE
import java.util.*;
class palindrome
{
public static void main(String[] args)
{
int n,n1,n2,n3,digit1,digit2,digit3,digit4,digit5;
Scanner keyboard = new Scanner(System.in);
System.out.println("Input a 5 digit number:");
n = keyboard.nextInt();
digit1 = n/1000;
n1 = n % 1000;
digit2 = n1 / 100;
n2 = n1 % 100;
digit3 = n2 / 10;
digit4 = n2 % 10;
n3 = n2 / 1;
digit5 = n3 % 1;
String total = String.valueOf(digit1)+String.valueOf(digit2)
+String.valueOf(digit3)+String.valueOf(digit4)+String.valueOf(digit5);
int sum = Integer.parseInt(total);
System.out.println("The number is " + sum);
if((digit1 == digit5) || (digit5 == digit1))
{
System.out.println("Number is a Palindrome");
}
else
{
System.out.println("Number is not a Palindrome");
}
}
}
Any guidance I can get would be great. Thank you for your time.
