Write a program in java to accept a number from the user and check whether it is a Palindrome number or not.

Palindrome number – a number is a Palindrome which when read in reverse order is same as read in the right order. Example: 121, 11, 15451, etc.

Program:

import java.util.*;

class Palindrome
{
  public static void main(String args[])
  {
    int n,s=0,r,t;
    Scanner sc=new Scanner(System.in);
    System.out.println("Enter the number to check its a palindrome or not:");
    n=sc.nextInt();
    t=n;
    while(n!=0)
    {
      r=n%10;
      s=(s*10)+r;
      n=n/10;
    }
    if(t==s)
    {
      System.out.println("Entered number is Palindrome");
    }
    else
        System.out.println("Entered number is not Palindrome");
  }

}

Output:

Enter the number to check its a palindrome or not:
121

Entered number is Palindrome

Enter the number to check its a palindrome or not:
12211

Entered number is not Palindrome
