how to find palindrome number in java code example

Example 1: easy palindrome program in java

import java.util.*;   
class PalindromeExample2  
{  
   public static void main(String args[])  
   {  
      String original, reverse = ""; // Objects of String class  
      Scanner in = new Scanner(System.in);   
      System.out.println("Enter a string/number to check if it is a palindrome");  
      original = in.nextLine();   
      int length = original.length();   
      for ( int i = length - 1; i >= 0; i-- )  
         reverse = reverse + original.charAt(i);  
      if (original.equals(reverse))  
         System.out.println("Entered string/number is a palindrome.");  
      else  
         System.out.println("Entered string/number isn't a palindrome.");   
   }  
}

Example 2: palindrome number in java

import java.util.Scanner;

public class Palindrome
{
  public static void main(String args[])
  {
    int num,temp,reverse=0;
    Scanner input=new Scanner(System.in);
    num=in.nextInt();
    temp=num;
    //code to reverse the number
    while(temp!=0)
    {
      int d=temp%10; //extracts digit at the end
      reverse=reverse*10+d;
      temp/=10; //removes the digit at the end
    }
    // 'reverse' has the reverse version of the actual input, so we check
    if(reverse==num)
    {
      System.out.println("Number is palindrome");
    }
    else
    {
      System.out.println("Number is not palindrome");
    }
  }
}
