• Students Tutorial

Hello world program

import java.util.Scanner; 
class Palindrome {   
 public static void main(String args[]) {   
  int rem,sum=0,rev;     
  int n=454;//It is the number variable to be checked for palindrome   
  
  rev=n;     
  while(n>0) {     
   rem=n%10;  //getting remainder   
   sum=(sum*10)+rem;     
   n=n/10;     
  }     
  if(rev==sum)     
   System.out.println("It is a palindrome number ");     
  else     
   System.out.println("It is not a palindrome number");     
}  
}  

Java palindrome program of a no (input through program)

import java.util.Scanner; 
class Palindrome {   
 public static void main(String args[]) {   
  int rem,sum=0,rev;     
  int n=454;//It is the number variable to be checked for palindrome   
  
  rev=n;     
  while(n>0) {     
   rem=n%10;  //getting remainder   
   sum=(sum*10)+rem;     
   n=n/10;     
  }     
  if(rev==sum)     
   System.out.println("It is a palindrome number ");     
  else     
   System.out.println("It is not a palindrome number");     
}  
}
