Java Program To Check Whether a Number is Palindrome or Not

Welcome back to my blog! In this post, you will learn how to check whether a number is a palindrome or not in Java.
A number is called palindrome if reads same when reversed. For example: 121, 111, 98789, etc.

So let's get started!
Algorithm:

• Enter the number which has to be checked.
• Assign the number to a temporary variable.
• Reverse the number.
• Compare the temporary number with the reversed number.
•  If both are same, print a message "The number is palindrome!"
• Else print "The number is not palindrome."

Given below is the code to check whether the number is palindrome or not:


class Palindrome {
public static void main(String[] args) {
     int rev, temp, sum = 0;
     int n = 121; // The number to be checked whether it is palindrome or not.
     temp = n;
                 while (n > 0) {
                    r = n%10; // Getting the remainder
                    sum = (sum * 10) + r;
                      n = n/10;
                }
if(temp == sum)
          System.out.println("The number is palindrome!");
else
         System.out.println("The number is not palindrome!");
}
}

Output:
The number is palindrome!
