Palindrome number in java: A palindrome number is a number that is same after reverse. For example-:

input-121

output-121

PROGRAM
class PalindromeExample{

public static void main(String args[]){

int r,sum=0,temp;

int n=454;//It is the number variable to be checked for palindrome

temp=n;

while(n>0){

r=n%10; //getting remainder

sum=(sum*10)+r;

n=n/10;

}

if(temp==sum)

System.out.println("palindrome number ");

else

System.out.println("not palindrome");

}

}

Answer 2

Palindrome number : If the numbers remains same even if we reverse its digits.

Ex: 121, 131, 111, .....

Sample program for palindrome number:

import java.util.*;

class Basic

{

public static void main(String[] args)

{

int a,b=0,c,d;

Scanner demo = new Scanner(System.in);

System.out.println("Enter a number: ");

a = demo.nextInt();

d = a;

while(a  > 0)

{

c = a%10;

b = (b * 10) + c;

a = a/10;

}

if(d == b)

{

System.out.println("Entered number is a palindrome");

}

else

{

System.out.println("Entered number is not a palindrome");

}

}

}

Output:

Enter a number : 153

Entered number is not a palindrome.

Enter a number : 121

Entered number is a palindrome

Hope it helps!
